[TimeBucks] Exclusive high credit with Your-Surveys

[TimeBucks] Exclusive high credit with Your-Surveys
Hi guys,
I joined TimeBucks due to an offer which I had mentioned before (here if you haven't read it yet). I noticed that sometime a really high credit survey appears (survey from Your-Surveys wall, which is quite familiar to many of us, especially who's doing survey regularly). I completed one of those yesterday, and be credited with $3, you can see the last one in the picture below .
Your-Surveys - exclusively high credit survey
With that $3, I was able to complete the "earn $5 with TimeBucks to be rewarded $8.5" offer, which I had expected to clear it in 1-2 weeks.
TimeBucks offer - $8.5
Your-Surveys is listed on many offer wall sites out there, but I don't see any exclusive high credit Your-Surveys survey on those sites but TimeBucks. If you're a survey-lover, I recommend taking a look.
They also have other surveys and offer wall tasks like installing app, sign-up, paid-to-click and paid-to-view,... but the payout rate for those is a little lower than some common sites I recommended here - pinned post. So make sure to pay attention to those exclusive high credit Your-Surveys, it's ok to do other surveys, offers or tasks in TimeBucks too (the payout rate is not much lower then common sites above), but it will be somewhat better in other common sites.
If you want to try, here are your registration links: ref-link and no-ref.
P.S 1: more information about TimeBucks
  1. They don't support withdraw to PayPal anymore. You can select other payment methods like Bitcoin, Payeer or AirTM
  2. The minimum to withdraw is $10
  3. They have a variety of offetask types. I haven't seen any other sites with the number of offetask types as high as them.
  4. They have weekly lotery, called sweepstake, where a total prize pool of $500 is awarded to 30 winners each week. It's quite attractive :D
P.S 2: In case you need a Crypto wallet, you can use Coinbase, registration links: ref-link and no-ref, or Binance ref-link and no-ref. You can read here for the comparison between Coibase and Binance

Not all alt-coins are scams (I hope)

What is this post about?

Bitcoin brought to light the power of cryptocurrency and blockchain technology. I wanted to share some other projects to show the world that blockchain technology is a viable solution to real world problems. I had a look into some of the projects that are disrupting industries like advertising, communication, energy, finance, gambling, video games, privacy, and social media - here’s what I found:


Personal data is gathered and sold to third parties, but the money never makes it to the user whose data has generated the value for the company using it.


Edward Snowden (among others) revealed the extent of surveillance technology collecting civilian communication data and expressed the need for a safe, secure and surveillance free method for individuals and businesses to communicate over the internet.


With the shift away from physical cash and the move towards online payments, user privacy is at risk. Digitalization often means more surveillance, privacy is more important than ever.


Energy markets are inefficient and act in the interest of the middlemen, not the generator or consumer. With the continual transition to cleaner energy, the energy sector is looking to leverage new and existing technologies.

Financial Sector

The financial system is out of date and in serious need of an update. Traditional banking only runs during business hours and cross border payments are exceptionally slow, inefficient and costly. As we continue transitioning to a more digital world, money is making the same change.


Gambling usually takes place in a physical or virtual casino, where the house always wins. Blockchain based gambling platforms will provide more transparency on how odds are formed, fees are charged and how payouts are scheduled.


With the introduction of IoT technology, the amount of data points being collected need to be managed and secured to avoid massive data breaches and leaks. The use of Blockchain technology can increase transparency and virtual incorruptibility.

Video Games

The video game industry is an ever evolving space which often adopted technological advancements before many others. The use of Blockchain is being explored for things such as in-game Microtransactions and digital collectables.


Typical social platforms are run by centralized companies and depending on their jurisdiction, they may not be able to serve certain people. Censorship resistance is critical to allow for freedom of speech.

Looking forward

There are literally thousands of projects out there, these are just some of the projects I've found to be doing interesting things. If I’ve missed something super important, let me know. I might look into blockchain projects next that have the most current active user bases if you guys like these kinds of posts.

I Created a Custom Lightning Payment Jackpot Website from Scratch, This Is What I Learnt

TL;DR: I wanted to learn how the Lightning Network operates. So I came up with an idea for a jackpot site using the Lightning Network to handle micro-payments. Operating a Lightning node is complicated and challenging for a beginner. Using custodial wallets like Wallet of Satoshi, BlueWallet or Breez is easy to use but not your keys. Please come by and help me test my Lightning integrated new website. I’m happy to help anyone that’s new to Lightning setup a wallet and play a game. It all helps with learning and adoption, that’s why we’re all here! Long Bitcoin, Short the Bankers!

Introduction: Welcome to a brand new concept in random number seeding. Generating a truly random number is quite hard. You could use the current time, divided by the RPM spin of your hard disk, squared by the temperature of your CPU, and so on. Other extreme methods include measuring quantum fluctuations in a vacuum, see ANU Quantum Random Number. All these methods are fine but none of these are really verifiable by a 3rd party. Whoever running the system can change the outcome. I'm not saying they do, simply stating that if the payoff was great enough to alter the 'reported' outcome they could. So what's different here? We're using the Bitcoin blockchain itself as the arbitrator. Every outcome is not only provably fair but verifiably fair and immutable. Trying to cheat this system is impossible.

So that’s the pitch. Make a website using the idea of whoever’s guess is closest, wins the jackpot; using Lightning to handle all the incoming and outgoing payments. I started to look around at other fully functional websites offering Lightning as a payment method. It turns out most use a 3rd party like OpenNode or CoinGate. To me, this defeats the whole purpose of Bitcoin. Why build a website/offer a service/offer Lightning as a payment method if you don’t even own or control your funds. A payment processor could simply turn off withdrawals and it’s over. Not your keys, not your coins!

It’s been quite a learning experience for me. I think the most frustrating thing to figure out and attempt to solve was channel capacity. For example, with a fresh new wallet setup on Bitcoin Lightning for Andriod (blue bolt logo), you can open a channel to anyone fine, but trying to receive money won’t work. I think for a beginneadoption this is the greatest hurdle to understand/overcome.
You need to spend money so the other side has some collateral to send back. One explanation I read was, opening Lightning channels are like a full glass of water, I need to tip some of my water into your empty glass so my glass has some room to fill it back up, it can’t overflow. Another one is like beads on a string. The number of beads is up to you but if all the beads are on your side, the other party can’t push any beats your way because you have them all. There’s ways to fix this. Either spend into the channel or buy incoming channel capacity. On the spend side, you can use websites like lightningconductor.net which allow you to send money to their Lightning node, from your new channel, and they’ll send the coins to your on-chain Bitcoin wallet. This is a simple way to empty your glass or push those beads to the other side and still retain all your money, minus LN and on-chain fees. For incoming capacity, you can use LNBig and get 400k satoshis of incoming capacity for free or lightningto.me, or you can pay lightningpowerusers.com or bitrefill.com to open larger capacity channels to you for a small fee.

For a beginner or someone new to Bitcoin/Lightning, using a custodial wallet like BlueWallet, Wallet of Satosh or Breez is far easier than trying to setup channels and buy or massage incoming capacity. You can simply install the application and using lightningconductor.net BTC to LN you can send some Bitcoin and they’ll forward it on to your lightning wallet, for a fee. These custodial wallets accept incoming transactions of 1 million satoshis or more. So now you’ve got a working wallet that’s got a few thousand satoshis, keep reading!

How to play: Two things are verifiable on the blockchain, time between blocks and transactions included in that block. First choose which block#, by default it will be the next one coming up. Then choose a public alias, others will be able to see your bets but they won’t know if you’ve paid or not, only you can see that. Next, guess the time it will take to mine the next Bitcoin or the number of transactions in that block. You can make multiple guesses. If you want to place a number of spread bets, I suggest opening a spreadsheet and getting it to generate the times or transactions for you. For example, put in 2300, then 2350, 2375, 2400, then drag down to generate as many in the sequence as you want. You can bet a maximum of 25 per invoice. This will hopefully ensure the small transaction amount will be successful. Once you’ve generated an invoice, pay it from the QR code or the lightning bolt11 string.
Now you’re ready to go. Wait till the next block goes active or the block you’ve bet on and you’ll see your bets and everyone else’s. Most importantly, what the final jackpot is. Unpaid invoices are discarded. If the block rolls over while you’re making up your mind the page will refresh and you could lose your input. Please plan your bets in notepad or a spreadsheet. I know this is annoying but I never claimed to be a UX codedesigner! It was a struggle getting all the css, ajax and javascript working, ahhhrrrrggg!! Next is the interesting part as this game can become competitive.

Game theory: As others make bets, you can encapsulate theirs. For example, they guess 2750 transactions, you can bet 2749 and 2751. While at first this seems unfair, what it doesn't show is what bets have been paid for and what have not. Only you can see your own bets that are paid and unpaid. To everyone else they look like paid bets. Only when the next block/jackpot starts can you see what's been paid for as unpaid bets are discarded. By placing dummy bets, unpaid, you can sucker someone in and greatly increase the jackpot payout at no cost to yourself. You can also use the same alias, for example, open up two different browsers, one for real bets and one for fake bets. This is why there’s a 25 bet limit, I don’t want people going too crazy with this. You can check your bets in the footer bar under ‘previous bets’. Also, IMPORTANT, please keep track of your account number at the top. If your session or browser has a problem, you can lose access to your bets and jackpot winnings. If this happens and you receive a new account number, simple use the claim jackpot in the footer to claim your winning jackpot. If you don’t have this, I can’t help you if something goes wrong. Rather than having a login/password system you have a unique account id. Don’t lose it! Now back to the blockchain.

What a minute… I though it took 10 minutes to confirm a block? Not always, actually it does this very rarely. If you average out every block over time, it averages around ten minutes. A block is confirmed when a miner takes transactions from the memory pool, up to ~1.2mb worth. Next, now this is the hard part, they need to generate a hash for that block, but it needs to start with X number of leading zeros. To achieve this, they use a random number called a nonce to seed/salt the hash and hopefully, it contains X number of zeros at the start of the block hash. If not, discard and keep trying. The winning block contains the miners local time, which can sometimes be wrong. This is why sometimes you get negative block times. See block #180966 then the next block, #180967's time stamp is before the first one! Who cares, as long as the later block references the previous block to keep the chain intact. You can’t guess negative numbers but you can guess 0 seconds. Which I guess is like betting on the green zero in roulette.

Ready to play?
Each bet is worth 5,000 satoshis. I wanted it to be expensive enough to prevent spam and also the jackpots be large enough that it would be worth playing. I hope you have fun.

Someone please make a decentralized, open source, non-biased sha-256 pool comparison site with up to date profit sheets that includes the top 5 pools. Please:)

I am trying to pick a pool and I keep ending up at ghash because I know what I am getting. The other pools I try either go offline or pay small amounts and I wish we just had a simple way to compare.

Beermoney Essentials: 6 Ways To Earn Passively With Cryptocurrencies In 2018

Hey guys!
This is my second "Beermoney Essentials" post. Here's the first one about Chrome Extensions if you missed it a year ago. These types of posts basically are just about things have seem to become 'essential' information in terms of Beermoney.
This post is going to be about Cryptocurrency. Cryptocurrency has been becoming more and more popular around the beermoney community, and I think it's safe to say that 2018 will be the year of cryptos.
Here's what this post is NOT. This post will not be the 'here's what cryptos I think you should buy and hodl in 2018'. This post IS going to be about cryptos you can get into and do whatever you want to without having to directly invest in them. So yeah, this post is mostly going to be about mining.

6 Ways To Earn Passively With Cryptocurrencies

Alright, so in this post, I'm going to split things up into 4 parts:

Part 1: GPU mining

Does anyone here remember Nice Hash? (I mean, it technically still is a thing actually). Nice Hash is/was a nice site that would allow you to use your PC to mine. I believe they actually mined ETH (I think), but they were nice because they paid out in BTC (which most people prefer). It was really the easy way for just about anyone to get into mining (assuming you have a decent GPU). Just a month or so ago they claim to have been "hacked" and they lost (at the time) ~$60 million in users' bitcoin. For whatever reason a lot of people wanted them to resume operating after the bits were lost, so they are back up. I won't recommend Nicehash at all. I don't think they were really hacked, and I do think it was an inside job. If you want to use Nicehash, you can. I just really don't recommend it, and there are plenty of alternatives. Here are just a few that I found.


WinMiner is a really neat alternative to NiceHash. From what it seems, the payouts on Winminer are a bit lower, but there are a couple advantages to using this site that might outweigh the lower payouts. First of all, Winminer is really easy to use, you can just download it and set it up, and it's all set. The thing about Winminer that is really nice is that you can get paid out in many different ways. If you want, you can cash out to Bitcoin, but they have a $100 minimum, and the fees are really high, so there's a good chance you won't want Bitcoin. Alternatively, you can withdraw your balance to PayPal, ETH, LTC, Amazon, or iTunes. One thing I don't necessarily like about Winminer is that it does keep your balance in USD at all times, so if you earn for a month and go to withdraw if bitcoin's price goes up 50% in that month, you won't get that bonus reflected on your total cashed out because it was in USD. It's probably not an issue for most people.

Kryptex | Nonref

I have been using Kryptex since just after the announcement of NiceHash being hacked. It has a nice UI and it is very customizable with its settings. This is probably the closest site to the original NiceHash. You can request a payout in Bitcoin any time after you have 0.0006 BTC. One thing about Kryptex is that it does have a referral system. You can earn 10% of your referral's earnings. I shamelessly put my referral link above. Feel free to give it a click if you want.
I don't really prefer this site over WinMiner because it doesn't offer quite as many methods of payments, but here it is anyways.

Part 2: CPU Mining

CPU Mining for Bitcoin has been dead for a long time, but there are still some ways to use your CPU to earn some crypto passively.


LoadTeam used to be a site that would pay you to test loading websites in the background passively. It was never a lot of money (and it still isn't), but they made the change a few months ago to switch over to Crypto Mining. I actually didn't even notice the switch, but I checked my account after a couple months and I had a few dollars sitting there. LoadTeam offers instant paypal transfers with no fee for all balances over $1. It's pretty nice. I didn't even notice a difference in CPU usage over the last few months. I think of it as an easy couple dollars a month, and it runs entirely in the background.

CoinHive Monero Mining

You might have seen this around a bit. CoinHive is a service that allows sites to mine monero in the background(ish). Some sites have been using Coinhive as an alternate to advertising/adblockers. There are a few sites that have been adding coinhive to their site. You can run this passively in the background.
I don't know all of the sites that have CoinHive, but two big ones I know of are FreeBitco.in and CoinPot.
FYI, I think Freebitco.in links are blocked on reddit, but if anyone wants my referral link, send me a PM. I give 100% of my referral earnings back to my referrals.

Part 3: PoC Mining

Burstcoin Mining

PoC Mining you might not have heard of, but it's fucking cool. PoC = Proof of Capacity. While CPU mining uses a computer's CPU, and GPU mining uses graphics cards, PoC mining uses free storage to mine. The appeal of PoC mining is that it seems like everybody has free storage. Check around your house, maybe you'll find a nice external hard drive with some space on it. You can use this to mine from.
Now I know I said above that this wasn't going to be a post of me telling you what cryptos I recommend for you to invest in, but here's my quick pitch for Burstcoin. Burstcoin is the worlds first (and only) PoC coin. It is the "green" crypto. Mining Burstcoin takes up 400x less power than a crypto like Bitcoin. It's really pretty fucking cool, and I absolutely support the coin. Feel free to read more about Burstcoin on /burstcoin, and check out the recent announcement of Dymaxion.
But you're here to learn how to earn from PoC Mining passively.
Unlike CPU and GPU mining, it is a lot more hard to get into because there are a lot more steps involved to setting it up. You'll actually need to know how to 'plot' your storage and set up a mining pool.
I'm not going to write out the entire process because there are plenty of other resources to help you out.
One thing I really recommend is QBundle 1.6, which is probably the closest thing that will walk you through the process of setting up a wallet for burst and start plotting and then mining with your storage.
One thing I'll also point out is that in order to mine burst with a pool you will need at least one burst in order to set the reward recipient. There are faucets you can get a free burst from, but if you can't get the faucets to work, feel free to send me a PM and I'll send over everyone who wants to get into burst a coin to set the recipient.
Here's a video explaining burstcoin a bit more: https://www.youtube.com/watch?v=Fyj9RIyxLb4
If there are requests, I will happily make a video explaining how to get started mining with Burstcoin.

Part 4: Saving/Investing

Okay, I said this post wasn't about investing in cryptos, and that's not what this section is about, at all.
This part of the post is about using the cryptos you already have to earn more crypto. There are quite a few options in this space, but I do advise you to take all caution when investing your cryptos into anything. Realize that ANYTHING can become a scam when you're not holding your own private keys.


I've mentioned this a few times in the past, but Freebitco.in allows you to use their site has a savings account/wallet and they pay 4.08% annual compounded interest per year on all your balances held (they pay interest daily). I've been hodling bitcoin on there on and off for quite a long while now and it's really nice. Another advantage I could point out is that their site does work as a wallet as well, and while bitcoin's fees are going crazy, you have the option of setting up an automatic weekly cash out (when you're ready to cash out your balance on their site) and the fee is just 3000 satoshi, or you can sign up for a 1-6 hour payment with a heavily reduced fee, or instant with a full average fee. It's really nice having those options.
Freebitco.in does offer a 25% referral bonus for all interest paid out on their site, and I wrote above:
FYI, I think Freebitco.in links are blocked on reddit, but if anyone wants my referral link, send me a PM. I give 100% of my referral earnings back to my referrals.
I have been paying 100% back for over a year now, and I don't plan on changing that.
Please remember: if you do deposit anything onto freebitco.in that is a risk you're taking.


There are a lot of different ways you can use Cryptocurrencies to your benefit. Even if you don't have a good CPU, GPU, or have much free storage, there are still options for you, and maybe you could even consider taking some of your profits from beermoney in 2018 and putting it into upgrading your own set up, or taking some profits and investing into the cryptos you support.

Apparently I made a video stating that this guy is legit and he put in $500 in my account about 90 days ago.
Now it's at $6000.
I'm not 18 yet so I can withdraw because he is asking for a alternative payout method like a credit card aside from just my localbitcoins account.

Bitgrin - WHO I AM - introduction for new miners & investors

Bitgrin - WHO I AM - introduction for new miners & investors


Bitgrin is a privacy focused cryptocurrency on a protocol level based on MimbleWimble and a fork of GRIN coin.
This is about freedom from censorship and the banker regime.
The technology of Grin meets the economics of Bitcoin, for the worlds first
- private,
- scalable,
- decentralized currency with sound economic model (limited supply)

If you're not clear on what i mean by scalability: Bitcoin has a 240 GB blockchain. Ethereum has a 1TB blockchain. BitGrin will stay below 1GB due to the way old transactions get compressed and pruned
that means i can put a full node on your phone, not just a light wallet but a true full node

Bitgrin mainnet launched the 8th of February 2019

Ticker: XBG
Block time: ~60s
Block reward: 4.5 XBG
Next Halvening: Block 2,102,400
Supply: 21,000,000

We dont need a central authority declaring stuff official, we need grass-roots support

Reddit : https://www.reddit.com/xbg


Purpose of MimbleWimble is that no one can see your coins or who you sent them too, while still knowing coins are valid.
This is a huge deal in privacy, and we wish that Bitcoin had that from beginning.

But looks like we have a 2nd chance now. Grin failed that in our eyes with horrible economics


Our team is anonymous that won't change
We've got a small team who has been in blockchain dev since around 2011 as well as application developers, good at making things user friendly.
This all started because we were working on the Kingfish wallet which was a Grin wallet, and some miner software for Grin. The tech was very cool, but then this emission schedule and the attitude of the core devs made us realize their priorities wrong.
So Kingfish partners joined bitgrin team. Many of us on the original team were not happy with the economic decisions.
We're actually pretty active in Grin Core team chat.


BitGrin is a store of value, designed to be easy to use
Bitgrin share the same halvening schedule as BTC. Half as many rewards every 4 years. 4.5 coins per block, and then 2.25 after halving, and so on.

So theres really 3 things we bring to the table
  1. We create an economic incentive for folks to hold there coins with halvenings. This means the coin acts more as a store of value.
  2. We create a dev fee so we don't have to be like the Grin team and beg for donations. We'll take modest salaries to keep things running clean
  3. We are building super simple user friendly tools on top of the protocol so that in time the average user can simply pull out a phone and work with XBG coins

BitGrin makes transactions completely private, hiding the amount of coins a user owns, how many have been sent, and to whom they were sent.

Transactions are blinded, which means no-one can prove that coins have been sent at all!

BitGrin is private by design, even the developers don't know who is sending or receiving coins.

But how does it all actually work?
BitGrin is governed by the laws of mathematics, exploiting some very simple properties of addition and multiplication.
Elliptic curve cryptography is at the root of what keeps BitGrin (and Bitcoin) secure. The standard is also used by countless military, banking, and even government operations. Elliptic curve cryptography is a method of utilizing a secure curve to produce privately known numbers These extremely large numbers are nearly impossible to guess, but can be proven to have been generated by someone with knowledge of their private key.

Let me walk you through the process.
First, a user picks a really, really, really large number. Then they multiply it with the starting point on the curve.
The resulting coordinates on the curve are your public key and that really, really big number is your private key!
You can now securely encrypt values utilizing your private key, and publicly share your encrypted messages along with your public key. Other users in the world can *prove* that you must have knowledge of the correct private key, without them knowing what it is.

And this is the bedrock of almost all cryptography. It keeps the whole world secure!
The trick here is that it's pretty easy to get the coordinates of your public key, but it's nearly impossible to discover another user's private key.

A simple analogy for elliptic curve cryptography
Knowing just the public key is like knowing the location of an indestructible box, with the world's most complicated lock. Without the private key, it is impossible to access it's contents.
This is where, for example, Bitcoin's security model ends.
BitGrin, on the other hand, goes a few steps further.
BitGrin hides your even your *public* key. So now no one even knows *where* your indestructible box is.
This means that no one can see how many coins you have, who you are sending coins to, or how many you have received.
All of this is accomplished using just a few additional mathematical tricks.

How Bitcoin transactions work
To further explain, let's first talk about how Bitcoin transactions work.
Lett’s say you, a Bitcoin user, want to send some funds to another user. You would announce publicly to the network your public key, the amount of coins you would like to send, and proof that demonstrates you are indeed the owner of these coins.
You can see the problem here.
If someone goes through the history of the blockchain, they can clearly see who you received the coins from, who you are sending them to, how many were sent, and even how many you have.
You don't really want people knowing all of that information, do you?
Do you share your bank statements with everyone? Of course not.
Now... How can we fix this? How can we make transactions more private?

How BitGrin transactions work
Let's go over a BitGrin transaction...
BitGrin transactions are completely different than Bitcoin transactions, You can think of them as just a blank credit card with no name, just the number, and everyone who knows this number can spend money with it.
What the blockchain holds is just a list of these "cards", while obscuring the amounts in them, and who is in possession of them, or even who had contents in them prior.

Let's say for example I want to send you three BitGrin.
What we need to do now is prove that I own a credit card (or multiple cards) with the total of at least 3 coins.
We also need to create a new card for you. One whose number is only known by you.
First, I send you a message via a secure channel in between our wallets.
"Hey, I want to send you 3 coins. Here's proof I own at least 3. I'll also pay the fee."
You receive the message and you can compute your part of what it takes to make a new card. Then you send me back the proof that you know the new credit card number,
while not revealing the number to me, by using a special type of encryption.
Next, you send me a very very big number you choose to obscure the amount of coins by moving them by this amount on the elliptical curve.
Then, add to it a public key of the credit card number, made with another operation on the graph.
This will prove you own the coins, without either user revealing their private keys.

Finally, I add the number of coins to the very big number you chose.

We can prove the number of coins didn't change because 5-5 is 0. This is validated by the network to prevent coins from being created out of thin air.
And 5 plus the BigNumber, minus 5 plus the BigNumber, is also zero. By adding a hidden big number known only to us, we hide the amount from everyone else.
I combined all these details together into one large commitment, and then submit it to the BitGrin network.
Now the network needs to validate that no new coins were created and that your new card is valid. This is all done with simple mathematics, and is completely secure.
You now received your money! While it may sound like a long process, all of it is done within less than 1 second from the BitGrin wallet.
Want to spice things up? Generate invoices, transact using QR codes or send it by pigeons!

We're not done yet. This is not all that BitGrin improves.
As you may know, BitCoin transactions can take a very long time to be confirmed, and running a Bitcoin node is a very computer-intensive process.
BitGrin on the other hand is both fast, and extremely scalable! The majority of spent transactions get removed, making the blockchain much smaller than traditional blockchains.
This is done by miners in every block, as well as the entire blockchain over time.

Soon, everyone will be able to download the entire blockchain and synchronize it within seconds or minutes, even on a low powered mobile device or a payment terminal at the local checkout.

With further work and research, BitGrin will improve even more, enabling truly private, scalable digital cash to see mass adoption.


- Goal to be simple for end user
Crypto is super hard to use, keeping your money private is impossible. Bitgrin solves those problems making the latest scientific breakthroughs in cryptography, usable by everyone, all while being built on robust bitcoin economics. Bitgrin paves the road to mass adoption
there is a lot of confusion about what crypto is for many folks think it is a way to make money by buying new coins and selling as they mature
ignoring the central idea of decentralized money.
Grin folks invented a better BTC, and then proceeded to apply infinite inflation for reasons I can't explain it's decentralized, lightweight, and fast
but you can't just mint 1 new coin every second, thats not sound monetary policy even USD doesnt do anything that extreme
and yet the buying power of USD falls, even with their small inflation schedule and we already know a schedule that seems to work: the Bitcoin schedule
so why not use this in combination with the lightweight blockchain approach of Grin?
Lightning Network doesnt solve BTC problems, because settlement is important, and scale means fees.
Bitgrin solves all of these problems by offering a truly lightweight settlement layer, with no arbitrary P2P layer on top

__________A few words about others MW coins_____________
Grin has Grin economics: infinite coins forever which is kind of insane, Grin could have easily just limited their supply but they refuse to do that.
Our key differentiator is our economically sound emission schedule
Beam and BitGrin are working towards the same kind of thing, or at least our goals are more in line than they are with the Grin team. Our approaches are pretty different, from a technology perspective though. I fully expect all three projects to coexist and hopefully make each other better
Being “non corporate” isn’t necessarily good. To some degree it’s useful to have profits, a core team, etc
But if it’s too corporate (Beam) then your whole organization is susceptible to issues of centralization such as being shut down by the government.
The decentralized nature of the software prevents that to some extent, but nothing beats being driven by a team of anonymous contributors. That is true censorship resistance. It’s a feature, not a bug.
But we don’t need them to lose for us to win, we can win together, I believe a symbiotic mutually beneficial relationship is ideal with the Grin team.


1M coins are put in to height-locked contracts
about 20k released per month, starting next March 2018
so at launch, dev team has 0 coins
10% for 4 yrs, which amounts to 4% of total supply over time
Just a reminder that the dev fee is quite modest. It’s not like we are holding 90% of the supply like ICOs like to do
1mln pub const DEV_FEE_TOTAL: u64 = 1_000_000; // 1M coins to match Satoshi's Bitcoin holdings >> line 58 https://github.com/bitgrin/bitgrin/blob/mastecore/src/consensus.rs
Payouts are staggered over 4 years by the smart contract
I think as far as the community goes, what you would WANT is developers who are paid for success in the same terms they would expect success as buyers/miners.


It took a lot of work to know what to change, and to understand GRIN codebase and then the generatioin of the genesis block wasnt documented
or it was, but it was incorrect.
Getting seed nodes up and running, making the miners work thousands of little details
BitGrin in particular also has rollback protection
Uses block hash checks to make sure the chain stays stable
BitGrin in particular also has rollback protection
Uses block hash checks to make sure the chain stays stable
Also worth noting this is something added by us. Grin doesn’t support block hash checking
It’s not possible to rewrite any meaningful amount of the chain through a 51% attack. Those attacks are quite limited in exclusively abusing double spend
The team is currently working on porting the entire codebase to be web friendly for web wallets, and offline/non-interactive transactions using BitGrin addresses
basically we want to include a tx pool so users dont need to share ips/files, and can simply use disposable "addresses".
A major improvement with we call XBGJS. This will include tools for other devs to make working with BitGrin easier
Adding non-interactive transactions will be a major improvement

It's compatible with all grin miners
so any grin miner that works with Grin will also work with BitGrin

Community will make those decisions when it comes to it, there is time till end of 2019.
We can fork in to a different PoW, as needed.

There are ongoing discussion about it on discord

We dont need a central authority declaring stuff official, we need grass-roots support

There is no coin other than bitgrin that has true privacy, scalability, and limited supply it doesn't exist.

I say the more the merrier, this is about growing MW and it’s ecosystem, not about one coin “beating” the other.

But either way competition is healthy, let’s see where this road leads.

Competition is needed for innovation to keep up at a high pace.

As part of my ongoing effort to develop stupid shit for Garlicoin, I present you: W-addresses!

“Wait, what?!” I hear you asking? Well…(buckle up, this is another one of my technical posts that goes on, and on…)
For some time now, I have been using native SegWit (Pay-to-Witness-Public-Key-Hash, P2WPKH) transactions for myself. Mostly because they have a 75% fee subsidy on signature data (which comes out on ~50% fee subsidy on the entire transaction, depending on the type of transaction) and I am dutch after all ;-)
It turns out that Garlicoin Core kind of supports them and kind of does not. If you manually register the transaction redeem script to your wallet (using the addwitnessaddress command) it will start recognizing them on the blockchain but gets kind of confused on how to deal with them, so it registers them all as ‘change’ transactions. Still, this means you can receive coins using these types of transactions and pay with them in all ways you can with regular Garlicoins, except your transactions are cheaper.
However, sending coins using native SegWit is quite a hassle. You can basically only do it by creating your own raw transactions (createrawtransaction, edit it to make it native SegWit, fundrawtransaction, signrawtransaction, sendrawtransaction). On top of this, any change address the wallet creates are still legacy/normal Garlicoin addresses, so you will end up with a bunch of unspent transaction outputs (UTXOs) for which you have to pay full fee anyway. I decided we (I) could do better than this.
But first a few steps back. What is this native SegWit anyway and weren’t people already using SegWit? Wasn’t there a user that just after mainnet launched accidentally made a SegWit transaction? So what the hell am I talking about?
To understand this, you will need to know a few things about what SegWit is and how Bitcoin Garlicoin transactions work in general. Note that this bit gets really technical, so if you are not interested, you might want to skip ahead. A lot.
First thing to understand is that addresses are not really a thing if you look at the blockchain. While nodes and explorers will interpret parts of a transaction as addresses, in reality addresses are just an abstraction around Bitcoin Script and an easy way send coins instead of asking people “hey, can you send some coins to the network in such a way that only the private key that corresponds to public key XYZ can unlock them?”. Let’s look at an example: say I ask you to send coins to my address GR1Vcgj2r6EjGQJHHGkAUr1XnidA19MrxC. What ends up happening is that you send coins out a transaction where you say that the coin are locked in the blockchain and can only be unlocked by successfully executing the following script:
OP_DUP OP_HASH160 4e9856671c3abb2f03b7d80b9238e8f5ecd9f050 OP_EQUALVERIFY OP_CHECKSIG
Now, without getting too technical, this means something like this:
As you can see, the address actually represents a well-known piece of script. This start making sense if you look at the decoded address:
26 4E9856671C3ABB2F03B7D80B9238E8F5ECD9F050 F8F1F945
The first byte (0x26, or 38) is the version byte. This tells the clients how the interpret the rest of the script. In our case 38 means Pay-to-Public-Key-Hash (P2PKH), or in other words the script mentioned above. The part after that is just the SHA1 hash of the public key and the final 4 bytes are a checksum to verify you did not make a typo when entering the address.
Enter SegWit. What SegWit exactly is depends on who you are talking to, however it mostly is a different transaction format/protocol. The main change of SegWit is that signature data is not longer included in the transaction (fixing transaction malleability). Instead transaction data is sent separate from the transaction itself and outside of the (main) blocks.
This is not really that much of an issue, except for the fact that people wanted to enable SegWit as a soft-fork instead of a hard-fork. This means that somehow unupgraded nodes needed a way to deal with these new transaction types without being able to verify them.
The solution turned out to be to make use of an implementation detail of Bitcoin Script: if a piece of script executes without any errors, the last bit of data determines whether the transaction is valid (non-zero) or invalid (zero). This is what they used to implement SegWit.
So what does this look like? Well, you might be surprised how simple a P2WPKH (the SegWit way of doing a P2PKH transaction) script looks:
00 4e9856671c3abb2f03b7d80b9238e8f5ecd9f050
Yes. That’s it.
The first byte is the Witness program version byte. I.e. it tells you how the other data should be interpreted (very similar to how addresses work). Then there is the hash of the public key. As you can see, SegWit does not actually use Bitcoin Script. Mostly because it needs old nodes to ‘just accept’ its transactions. However interestingly enough, while the transaction format changed, the transaction data is pretty much the same:
This means that these kind of SegWit transactions need a new way of addressing them. Now, you might think that this is where the ‘3’ addresses on Bitcoin or the ‘M’ addresses on Garlicoin come in. However, that is not the case.
These addresses are what are called Pay-to-Script-Hash (P2SH) addresses. There scrypt is like this:
OP_HASH160 35521b9e015240942ad6b0735c6e7365354b0794 OP_EQUAL
Huh? Yeah, these are a very special type of transactions, that kind of go back to the “hey, can you send some coins to the network in such a way that only the private key that corresponds to public key XYZ can unlock them?” issue.
These transactions are a way to have arbitrary smart contracts (within the limits of Bitcoin Script) to determine whether a transaction output can be spend or not without the sender of the coins having to deal with your scripts. Basically they use a hash of the “real” script, which whoever owns the coins has to provide when they want to spend them, as well as the specific inputs required for a script. This functionality is for example used in multi-signature (MultiSig) wallets, without requiring someone sending money to these wallets having to deal with random bits of information like how many signatures are required, how many private keys belong to the wallet, etc.
This same method is used for so called P2SH-wrapped SegWit transactions (or P2SH-P2WPKH). Consider our earlier SegWit transaction output script:
00 4e9856671c3abb2f03b7d80b9238e8f5ecd9f050
Or 00144e9856671c3abb2f03b7d80b9238e8f5ecd9f050 in low-level hex. The P2SH script for this would be:
OP_HASH160 a059c8385124aa273dd3feaf52f4d94d42f01796 OP_EQUAL
Which would give us address MNX1uHyAQMXsGiGt5wACiyMUgjHn1qk1Kw. This is what is now widely known and used as SegWit. But this is P2SH-wrapper SegWit, not native or "real" SegWit. Native would be using the data-only SegWit script directly.
The reason for using the P2SH variant is mostly about compatibility. While SegWit nodes understand these newer transactions, they were never officially assigned a way to convert them to addresses. Hence, they will show up in blockchain explorers as Unparsed address [0] or something similar. Then there is also the whole thing about old nodes and relaying non-standard transactions, but I will skip that bit for now.
Bitcoin is using/going to use new BECH32 addresses for native SegWit transactions, which looks completely different from the old Base-58 encoded addresses. However, right now, especially on Garlicoin, you cannot really use them and have to use the P2SH variant. But why not use these new cool transaction types without having to deal with all that useless and complex P2SH wrapping, right? Right? …
Well, I went ahead and gave them their (unofficial) address space.
So last thursday I made some changes to Garlicoin Core, to make dealing with these native SegWit transaction a lot easier. In short, the changes consist of:
  • Assigning address version byte 73 to them, in other words addresses starting with a ‘W’ (for ‘witness’).
  • Allowing the use of ‘W’ addresses when sending coins.
  • Make the wallet automatically recognize the SegWit transaction type for any newly generated address.
  • Add the getwitnessaddress command, which decodes a version 38 ‘G’ address and re-encodes the same data as a version 73 ‘W’ address (unfortunately it is not as simple as just changing the first letter). Note that this can be any address, not just your own. (That said, you should not send SegWit transactions to people not expecting them, always use the address given to you.)
  • Added the usewitnesschangeaddress configuration setting, to automatically use the cheaper SegWit transaction outputs for transaction change outputs.
  • (Since using the 'W' address only changes the way coins are sent to you and the private key used for both transaction types is the same:) When receiving coins they show all up under the original ‘G’ address, whether a SegWit or legacy/normal transaction type was used. The idea behind this is that both are actually the same "physical" (?) address, just to the way to coins to it differs. Address book entries are also merged and default to the ‘G’ address type.
Anyway, I don’t expect people to actually use this or it getting merged into mainline or anything. I actually mostly made this for myself, but thought I should share anyway. I guess it was also a nice opportunity to talk a bit about transactions and SegWit. :-)
Btw, I also changed my pool to allow mining to ‘W’ addresses, to make coin consolidation cheaper (due to the SegWit fee subsidy). Right now this is only for instant payout though (as I would have to update the wallet node the pool is using for daily payout, which I haven’t done yet).
Also note that you can actually mine to a ‘W’ address (and therefore use cheaper transactions) even if you are running the official, non-patched version of Garlicoin Core, however:
  • You need to manually convert your ‘G’ address to a ‘W’ address.
  • You need to run the addwitnessaddress command (Help -> Debug Window -> Console) to make the wallet recognize SegWit transactions (you can ignore the ‘M’ address it produces).
  • The wallet might get a bit confused as it does not really understand how it got the coins. This is mostly notable in the ‘Coin Control’ window if you have it enabled. Apart from that everything should still work though.

MiningPoolHub + NiceHash + WhatToMine = ?

Hi all!
Let's assume someone has the following mining objectives:
  1. Build a setup-and-forget rig, because personal time is too important to be entirelly spent monitoring hashing power and currency rates.
  2. Always mine the most profitable coin for their hardware, even if that means changing to other pools.
  3. Automatically exchange all mined coins to preffered one.
At this time the 2 most popular ways to approach these objectives are:
  1. NiceHash. It pays in BTC but has 2 disadvantages: a) Its switching algo is not transparent, so you can't be sure they always choose the best for you and b) You can't change the payout coin.
  2. MiningPoolHub. You can choose the payout coin and it supports both in-algo and multi-algo coin switching.
  3. MultiPoolMiner. Powerfull but, no GUI?
Methods (1) and (2) are different pools and cannot be used simultaneously for auto switching.
So what's left? is there a way to easily setup a rig for auto switching, without limits regarding algos, pools and miners?
Please let me know if I'm missing something.
What I am trying to do:
Yesterday I built a new small rig with 2 1070ti.
I'm using BiggerDigger, a mining automator I created.
(This post is not about promoting it, I just need some advice)
I set it up to check WhatToMine.com every 10 minutes and auto mine the most profitable coin for my hardware, using ccminer and EWBF.
The 'miners.txt' file is as follows:
# USAGE: coin_name | miner_executable | parameters | pool | wallet
BitcoinGold | C:\Miners\EWBF\miner.exe | --server europe.equihash-hub.miningpoolhub.com --user user.worker --pass x --port 20595 | https://bitcoin-gold.miningpoolhub.com/index.php?page=dashboard | https://bitcoin-gold.miningpoolhub.com/index.php?page=account&action=pooledit Nicehash-Equihash | C:\Miners\EWBF\miner.exe | --server equihash.eu.nicehash.com --user user.worker --pass x --port 3357 | https://www.nicehash.com/minemy | https://www.nicehash.com/wallet Nicehash-Lyra2REv2 | C:\Miners\ccminer\ccminer-x64.exe | -a lyra2rev2 -o stratum+tcp://lyra2rev2.eu.nicehash.com:3347 -u user.worker -p x | https://www.nicehash.com/minemy | https://www.nicehash.com/wallet Zcash | C:\Miners\EWBF\miner.exe | --server europe.equihash-hub.miningpoolhub.com --user user.worker --pass x --port 20570 | https://zcash.miningpoolhub.com/index.php?page=dashboard | https://zcash.miningpoolhub.com/index.php?page=account&action=pooledit Zclassic | C:\Miners\EWBF\miner.exe | --server europe.equihash-hub.miningpoolhub.com --user user.worker --pass x --port 20575 | https://zclassic.miningpoolhub.com/index.php?page=dashboard | https://zclassic.miningpoolhub.com/index.php?page=account&action=pooledit Zencash | C:\Miners\EWBF\miner.exe | --server europe.equihash-hub.miningpoolhub.com --user user.worker --pass x --port 20594 | https://zencash.miningpoolhub.com/index.php?page=dashboard | https://zencash.miningpoolhub.com/index.php?page=account&action=pooledit
In brief, I set it up to:
I'd appreciate any answer to the following questions:

such beginner shibe thread wow how to get coin

 how to shibecoin v rich in minutes much instruct so simple any doge can do 


UPDATE 1/21/14: I'm not updating this guide anymore. Most of the steps should still work though. See the wiki or check the sidebar for updated instructions.
Before you do anything else, you need to get a wallet. Until there's a secure online wallet, this means you need to download the dogecoin client.
Now open the client you just downloaded. You'll be given a default address automatically, and it should connect to peers and start downloading the dogechain (aka blockchain in formal speak). You'll know because there will be a progress bar at the bottom and at the lower right there should be a signal strength icon (TODO: add screenshots).
If you've waited 2 or 3 minutes and nothing is happening, copy this:
maxconnections=100 addnode= addnode= addnode= addnode= addnode= addnode=doge.scryptpools.com addnode=doge.netcodepool.org addnode=doge.pool.webxass.de addnode=doge.cryptopool.it addnode=pool.testserverino.de addnode=doge.luckyminers.com addnode=doge.cryptovalley.com addnode=miner.coinedup.comdoge addnode=doge.cryptoculture.net addnode=dogepool.pw addnode=doge.gentoomen.org addnode=doge.cryptominer.net addnode= addnode= addnode= 
And paste it into a new text file called dogecoin.conf, which you then place into the dogecoin app directory.
Now restart your qt client and the blockchain should start downloading in about 1-2 minutes.
Once it finished downloading, you're ready to send and receive Dogecoins!


Decide how you want to get Dogecoin. Your options are:
I'll go into detail about each of these. I'm currently writing this out. I'll make edits as I add sections. Suggestions are welcome.


Mining is how new dogecoins are created. If you're new to crypto currencies, read this. To mine (also called "digging"), a computer with a decent GPU (graphics card) is recommended. You can also mine with your CPU, but it's not as efficient.


These instructions cover only Windows for now. To mine, you'll need to figure out what GPU you have. It'll be either AMD/ATI or Nvidia. The setup for both is approximately the same.

Step One: Choose a pool

There's a list of pools on the wiki. For now it doesn't really matter which one you choose. You can easily switch later.
NOTE: You can mine in two ways. Solo mining is where you mine by yourself. When you find a block you get all the reward. Pool mining is when you team up with other miners to work on the same block together. This makes it more likely that you'll find a block, but you won't get all of it, you'll have to split it up with others according to your share of the work. Pool mining is recommended because it gives you frequent payouts, because you find more blocks. The larger the pool you join, the more frequent the payouts, but the smaller the reward you get.
Over a long period of time the difference between pool and solo mining goes away, but if you solo mine it might be months before you get any coins.

Step two: Set up pool account

The pool you chose should have a getting started page. Read it and follow the instructions. Instructions vary but the general idea is:
When you're done with this, you'll need to know:

Step three: Download mining software

For best performance you'll need the right mining software.
Unzip the download anywhere you want.

Step four: Set up miner

Create a text file in the same folder as your miner application. Inside, put the command you'll be running (remove brackets).
For AMD it's cgminer.exe --scrypt -o stratum+tcp://: -u -p
For Nvidia it's cudaminer.exe -o stratum+tcp://: -O :
Substitute the right stuff in for the placeholders. Then on the next line of the text file type pause. This will let you see any errors that you get. Then save the file with any name you want, as long as the file extension is .bat. For example mine_serverName.bat.

Step five: Launch your miner

Just open the .bat file and a command line window should pop up, letting you know that the miner is starting. Once it starts, it should print out your hash rate.
If you now go to the pool website, the dashboard should start showing your hashrate. At first it'll be lower than what it says in the miner, but that's because the dashboard is taking a 5 minute average. It'll catch up soon enough.
NOTE: A normal hashrate is between 50 Kh/s up to even 1 Mh/s depending on your GPU.

You're now mining Dogecoins

That's it, nothing more to it.


CPU mining isn't really recommended, because you'll be spending a lot on more on power than you'd make from mining Dogecoin. You could better spend that money on buying Dogecoin by trading. But if you have free electricity and want to try it out, check out this informative forum post.


Trading has been difficult so far, but Dogecoin just got added to a few new exchanges. If you don't have a giant mining rig, this is probably the best way to get 100k or more dogecoins at the moment. I'll write up a more complete guide, but for now check out these sites:


Faucets are sites that give out free coins. Usually a site will give out somewhere between 1 and 100 Dogecoin. Every site has its own time limits, but usually you can only receive coins once every few hours, or in some cases, days. It's a great way to get started. All you do is copy your address from the receive section of your wallet and enter it on some faucet sites. Check out /dogecoinfaucets for more. If you go to each site on there you might end up with a couple hundred Dogecoin!


This method is pretty straightforward. Post your receiving address, and ask for some coins. Such poor shibe. The only catch is, don't do it here! Please go to /dogecoinbeg.


At the moment there are two tip bots:
Other redditors can give you Dogecoin by summoning the tip bot, something like this:
+dogetipbot 5 doge
This might happen if you make a good post, or someone just wants to give out some coins. Once you receive a tip you have to accept it in a few days or else it'll get returned. Do this by following the instructions on the message you receive in your inbox. You reply to the bot with "+accept". Commands go in the message body. Once you do that, the bot will create a tipping address for you, and you can use the links in the message you receive to see your info, withdraw coins to your dogecoin-qt wallet, see your history, and a bunch of other stuff.
As a bonus, so_doge_tip has a feature where you can get some Dogecoins to start with in exchange for how much karma you have. To do this, send the message "+redeem DOGE" to so_doge_tip. You'll need to create a tipping account if you don't have one.
If you want to create a tipping account without ever being tipped first, message either of the bots with "+register" and an address will be created for you.

Working of Cryptocurrency Mining pool

Working of Cryptocurrency Mining pool
Cryptocurrency is the most discussed and trending topic on various internet forums, communities, and social media. Many individuals are keen to enter the cryptoworld and unfold all the profits within it. Cryptocurrency can be bought from an exchange or mined through the mining pools. In this guide, we’ll understand the working of the cryptocurrency mining pool.
What is Mining Pool?
Cryptocurrency mining is the same as mining the metals from the earth. The individual or company that digs out the metal from the earth becomes the owner similarly the individual who discovers first the valid hash using the computational power becomes the owner and earns a block reward. The crypto mining can either be done solo using his/her own mining devices or through a mining pool.
As more and more enthusiasts participated in mining to earn a block reward became equally difficult and it would take centuries for a miner to generate a block because the probability of finding the hash value first and generating a block is directly proportional to the computing power in the network. The smaller the computational power the smaller is the chance of generating the next block. Hence a solution, to this problem mining pools were formed.
A mining pool is a group of miners pooling/combining their computational power together in order to mine a cryptocurrency quickly and earn a block reward consistently. Each contributing miner earns reward according to their investment in processing power. The working of mining pools depends on certain algorithms that are designed to check the authenticity and validity of the transactions. Miners are required to solve a complex math problem that requires millions of calculations with the help of High computational power. When the miners combined their computational power the block generation process happens at a much faster rate as compared to a single mining rig. For more understanding of mining please refer our previous blog (What is Bitcoin mining?)
Types of Mining Pools
  • Single mining pools: This type of mining pool mine only single cryptocurrency
  • Multi-currency pools: This type of mining pool mine different cryptocurrencies and gives the miner a chance to choose the cryptocurrency for mining timely depending rewards points offered.
  • Cloud mining pools: Cloud-based mining can be combined with mining pools by making an online contract. This type of mining pool allows individuals to participate in mining activity without even buying specialized equipment.
How rewards are shared on mining pools?
The rewards shared after successfully adding the new block to the blockchain vary from currency to currency. The reward sharings also depend on the factors like mining difficulty, the exchange rate between different coins, the hash rate and the block generation time. Some of the followed reward structures are as follows:
  1. Pay-per-share (PPS): This method offers instant payout depending on the miner’s contribution to finding the block. The payment is done using the pool's existing balance and can be withdrawn immediately.
  2. Shared Maximum Pay Per Share (SMPPS): It is the same as Pay-per-share (PPS) but limits the payout to the maximum that the pool has earned.
  3. Equalized Shared Maximum Pay Per Share (ESMPPS): This method is similar to (SMPPS) but the rewards are distributed equally among all miners in the pool.
  4. Proportional (PROP): The miner is rewarded the share that is proportional to the number of shares he has in the pool with respect to the pool’s total shares
Advantages of mining pools
  • Mining pools offer a more stable income
  • Mining pools lower costs of mining
  • Mining pools helps in generating a higher income
Disadvantages of Mining pools
  • There may be some interruptions in the Mining pools
  • There is a sharing of block rewards
  • There may be sometimes unfavorable pool reward structure
Widely-Used Mining Pools
  • Antpool: The largest pool available on the web offering mining of cryptocurrencies like BTC, BCH, LTC, ETH, ETC, ZEC, DASH, SCC, XMC, BTM
  • Minergate.com: A public mining pool mining of cryptocurrencies like ETH, ETC, ZEC, BTG, BCN, XMR, XMO, FCN, XDN, AEON
  • Btc.com: The most popular mining pool among miners offering cryptocurrencies BTC, BCH, ETH, ETC, LTC, UBTC, DCR to mine
  • BTCC: The largest Chinese pool in the world mining 7% of all existing blocks.
  • Slush: The most trusted mining pools on internet mining 7% of all available blocks.
Mining pools can definitely be a change to the entire mining process offering the highest and the real income without spending years depending on the computational powers. Hence, investing in a mining pool can be beneficial but always choose the mining pool that fits your personal needs and facilities.

Converting Beermoney GCs for Cash (Offering 1:1 conversion)

Today I'm going to answer a question that I see reposted here about every month.

How to convert a gift card to USD?

A fair majority of this sub (according to the 2017 demographics survey) likes to get paid via PayPal. It's just a fact.... but unfortunately several beermoney sites/apps only will send payments via gift cards. According to the survey just over 20% of this subreddit prefers to get paid via Amazon gift cards, which makes it the second most popular payout option. When someone gets paid via Amazon gift cards, there's a chance that they might want to swap it out for actual money that they can use on anything... and that's where this question pops up from so frequently. So let's run down the options.

Peer to Peer Transfers

I have peer to peer transfers at the top of this list because in my opinion, this is your best route, and I'll talk about why below.
Regardless of where you go to transfer your gift cards, you'll likely have to take a hit on the transfer. Though it is debatable, Amazon seems to be the best option as far as gift cards go. Not only are they the most popular gift card, but they often will sell for the highest rates.
So let's get into peer to peer transfers. Since we're on reddit, I think it's good to point out the subreddits where you can exchange gift cards. /GiftCardExchange and /GCTrading. Both of these subs are insanely similar, and if possible I actually encourage you to make your trading posts on both of these subreddits so you'll get the biggest audience possible. Both subs are active and have moderators who try to keep things as safe as possible.
So here's how it works:
You'll make a post on these subreddits saying "[H] <$X gift card here> [W] " and users on the subreddit can comment on your post and send you a PM if they are interested in buying your gift cards. This is a really brief overview of the process, but it's actually pretty simple.
Alright, here are some pros/cons for going for GCX or GCT:

Gift Card Websites

If you'd rather go without dealing with people, you can also try selling your gift cards to a gift card site.
Here are some examples:
I stated above that I don't really recommend these sites as much as I'd recommend a peer to peer transaction, and I hope to explain that in my pros/cons.

My Offer

Prime Day is coming up soon (the date(s) were leaked last month), and fuck it, right? Let's do some marketing for /GCTrading.
Through Sunday July 8, 2018 (or until I reach my cap, or I stop the offer for my own reasons, more below in terms), I will be offering a 100% rate for Amazon.com gift cards that are obtained through beermoney sites/apps, which actually makes it the best rate I think you can get anywhere. For this offer I'm only paying via PayPal. So yeah, since there are some sites that give you discounts for picking gift cards over PayPal, this will likely end up being a better deal for you than to take PayPal. Also there's no fees if you're in the US.
Just figured I'd put this offer out there for anyone interested.
If you're interested in trading any amazon gift cards with me check out my post here.

Is Genesis Mining worth it? I created a Genesis Mining profitability calculator in Google sheets to find out.

TL;DR: I attempt to overcome the pitfalls of forecasting genesis mining contract profitability for Ethereum, Monero, and Zcash.
The original Medium post can be found here: https://medium.com/@spreadstreet/is-genesis-mining-worth-it-a-genesis-mining-profitability-calculator-youll-actually-use-a06d916bf7bc
BitPay is on pace to process over $1B annually in bitcoin payment acceptance and payouts, and has already grown their payments dollar volume 328% year-over-year, according to a recent blog post on the BitPay website.
The very nature of cryptocurrencies requires transactions to be verified by miners. What does this mean?
  1. Cryptocurrency transactions are verified by a network of nodes, then recorded in a publicly distributed ledger known as a “blockchain”, which authenticates the coins as monetary units of measurement – or money.
  2. Cryptocurrency mining refers to coins created as a reward in which the users of the network verify and record transactions on this very blockchain. Users who are able to successfully verify the transactions receive fees and rewards in the form of brand new coins.
And Genesis Mining stands as the largest cryptocurrency cloud mining company in the world.
A user can rent "hashing power" in the form of a two-year contract from Genesis for a one-time, upfront fee.
In turn, they receive daily payouts of whatever specific cryptocurrency they purchased the contract for.


While Genesis Mining has done a great job breaking down a complex problem into an easy-to-understand business model, users consistently have one big question:
"How profitable is {x} contract?" - Everybody, ever
While the user is able to see the upfront cost, they are unable to get an idea of how many coins they will receive by the end of the contract.


The problem exists, because of two major uncertainties surrounding cryptocurrencies:
  1. Where the price of the currency will fluctuate over time
  2. Where the network hashrate (aka, the mining power of the entire network) will fluctuate over time
Both of these inputs are extremely volatile, and have a huge degree of uncertainty in the near and distant future.
What I will attempt to do in this exercise, is build a profitability calculator for Ethereum, Monero, and Zcash. Each of these cryptocurrencies is currently available on the website as of 11/7/2017.
Each cryptocurrency has three contracts, and I will formulate 4 different scenarios to try and capture a profitability "range".
Note: Do not take any of the words in this post as financial advice or recommendations. These are merely simulations that have their own issues and pitfalls, and are not to be used as the end-all, be-all decision.


Due to the difficulty in forecasting both price and nethash, I was forced into a few assumptions:
  1. The forecasted price method is a Monte Carlo simulation using a geometric Brownian Motion ran 1,000 times. I covered the full methodology in a prior blog post
  2. The base network hashrate follows along very closely with the movements in price. This assumption I am the least confident about, as network hash has been shown to deviate at certain times
  3. I attempt to cover the shortfall in network hash rate with two different scenarios (shown below).
  4. I assume we hold all coins until the end of the contract, and assign a value to the portfolio based on $USD
  5. I do not run any scenarios of converting a currency into another currency
  6. I do not account for any significant changes to the underlying algorithm, such as the "Casper" Ethereum update (see 'THE DIFFICULTY BOMB' below)
Obviously any slight change could drastically alter these assumptions, but let's take a look at the different scenarios.


Description of Scenarios
Instead of calculating just a base scenario (which every other calculator on the web does) I wanted to come up with different scenarios to get an idea of what could be.
  1. Base - Assume no change in price or network hashrate for the duration of the contract
  2. Median - Run a full 1,000 trial simulation of prices and network hash rate, and use the median values for each
  3. Conservative - The same as Median, but instead use a price forecast that is 1 standard deviation below the median price
  4. Aggressive - The same as Median, but instead use a price forecast that is 1 standard deviation above the median price


  1. Spreadstreet Google Sheets Add-in
  2. Bitfinex API - To pull in historical data for each currency
  3. WhatToMine API - For nethash statistics
  4. CoinMarketCap - Updated prices


The only way to utilize Ethereum is with the product from mining.
But this shortchanges the additional value of mining Ether. It is also absolutely required for securing the Ethereum network as it creates, verifies, publishes, and propagates blocks in the blockchain.
The overall term "Ethereum Mining" is the process of mining Ether. Ether is an absolute essential, as it serves as fuel for the smooth running of the Ethereum platform.
Ether is used as an incentive to motivate developers to create top notch applications.


Sometime in the future (we can't be certain when), ethereum will likely switch from its proof-of-work consensus algorithm to Casper, a proof-of-stake system its developers are now in the throes of completing.
From Blockonomi:
As opposed to the PoW consensus protocol, the PoS protocol achieves consensus through stakers—sometimes referred to as minters, too—who “stake” their coins by locking them down in specialized wallets.
With these stakers at work, mining will become redundant, meaning the Ethereum network post-Casper will rely on stakers and staking pools instead of miners for its operability.
Genesis Mining has a prelim plan in place for this scenario:
The Ethererum Mining plans will run for a maximum of 24 months, however, should Ethereum (“ETH”) switch to proof-of-stake before the end of the term, we will use the leased hardware on a best-effort basis to mine the most profitable coin with that hardware for you.
Very simply put, this changes the economics of contract profitability significantly. We are going to ignore that update for now, but it may make sense to stay away from the contracts in the short-term.


Ethereum Mining Contracts Comparison


Ethereum One Year Price Simulation
Here we can see one of 1,000 price simulations run to inform our forecast for the Median, Conservative, and Aggressive scenarios.
*Why is the price so high? This is what happens when you have a volatile currency in a simulation that does not have changes in said volatility. When a currency can move 20% in one day, it is not uncommon to see price movements like this. I mean, shit, Ethereum grew 25x in one year.


Ethereum Profit and ROI Comparison


Base performance ranges from 30% to 39% ROI, and is higher than the Median scenario by ~10%.
The conservative scenario shows a loss of between 59-62%, and the aggressive scenario shows a gain between 318% and 347%.
Difficulty bomb in the near-future presents tremendous uncertainty.


From Cryptocompare:
Monero (XMR) is a Cryptonote algorithm based cryptocurrency, it relies on Ring Signatures in order to provide a certain degree of privacy when making a transaction. Monero is a Proof of Work cryptocurrency that can be mined with computational power from a CPU or GPU. There are currently no ASICs for Monero, which means that anyone with a computer can mine it.


Monero Mining Contracts Comparison


MoneroOne Year Price Simulation
We run the same Monte Carlo simulation to inform our forecast for the Median, Conservative, and Aggressive scenarios.
Why is the price so high? See Ethereum up above.
How is it possible for the "Conservative" scenario to be higher than the base price? Good question, and i'm glad you brought it up. The Monero currency has been not only really volatile, but drifting upwards at a pretty high rate.
The results are also being skewed by a recent uptick on November 6th where the price jumped by ~18%.
This may represent an opportunity for contract investment, but more analysis is needed.


Monero Profit and ROI Comparison


Base performance ranges from 87% to 95% ROI, with performance in the Median scenario lower by 5-6%.
The conservative scenario shows a loss of between 63-64%, and the aggressive scenario shows a gain between 795% and 832%.
To reiterate, the aggressive scenario is very much influenced by the recent uptick in volatility, so be weary of those high numbers.


ZCash uses Equihash as an hashing algorithm, which is an asymmetric memory-hard PoW algorithm based on the generalized birthday problem (I don't know what the hell this means, but it sounds fancy).
It relies on high RAM requirements to bottleneck the generation of proofs and making ASIC development unfeasible, much like Ethereum.


Zcash Mining Contracts Comparison


Zcash One Year Price Simulation
Here we can see one of 1,000 price simulations run to inform our forecast for the Median, Conservative, and Aggressive scenarios.
*Why is the price so high? See: Ethereum up above.


Zcash Profit and ROI Comparison


Base performance ranges from 51% to 65% ROI, and surprisingly lags the Median scenario by 4-6%.
The conservative scenario shows a loss of between 56-60%, and the aggressive scenario shows a gain between 490% and 540%.


The initial upfront costs and potential profitability are hidden when investing in hashing power contracts like Genesis Mining.
However with some robust analysis, we can get a better idea of how to assess the potential profitability of a two-year deal.
As we continue to evolve our thinking, better methods and analysis will eventually surface. Hopefully this industry can become a great avenue for side income.

Getting Started with Bytecoin: A Beginner’s Guide

In this post, I discuss exactly what you need to start exploring cryptocurrency, particularly Bytecoin. It took me several days to learn this information through trial and error. Using information in this post, however, you should be able to start using cryptocurrency in less than a day. Specifically, I will discuss three things you must do to started, namely:
  1. Downloading a compatible wallet;
  2. Creating a .wallet file and syncing the wallet with the blockchain; and
  3. Getting Bytecoin by mining for it or purchasing it from someone who already has it.
In all honesty, these are the very basics of cryptocurrency, and you can apply the steps to almost any other currency, including Bitcoin. Similarly, I could write an entire post on how to configure your computer, so you reap the most amount of profits on Bytecoin UK, for example, but that is just beyond the scope of this post.
If, however, you find this post helpful, please donate BCN here: 21DUzLdrRHuX9A1d8P2NMSZFAo8XETxybEYjAhV3RdcmYePkCmjM9hoEVhPFQB4MofSeJPdjHhJSJRWjiBTyrY132LnDJT2
------------------------------------------------------Getting a Wallet----------------------------------------
The most secure way to store your Bytecoin is by installing a wallet, which is nothing more than a program that allows you to send and receive Bytecoin as well as mine for Bytecoin, on your laptop or desktop.
The best way to acquire the wallet is to visit the developer of Bytecoin’s website (i.e., https://bytecoin.org/downloads) and download it. Since Bytecoin is constantly being improved, I would recommend that you download the Beta version of the desktop wallet. Having just installed it myself, I know it's working just fine.
Once you download it, you will want to install it, and at this point, your anti-virus software may flag it as a virus, but it isn’t. It is 100% safe.
Next, you’ll want to create your wallet, which will require you to set a password. At the top of your wallet, click wallet and then create wallet, which should prompt you to enter a password. In creating a wallet, you'll notice that your wallet creates a .wallet file; you will want to save this somewhere safe, since it contains all of the information about your wallet. In other words, this is the file you can open to view your account.
As soon as you create the wallet, your wallet will begin synchronizing with the blockchain, which is a ledger of all of the transactions that have taken place with Bytecoin.
Depending on how fast your internet connect is, this process will take approximately 3 to 8 hours to complete, and it will take up a lot of your computer's resources, particularly its hard drive. This is completely normal, and once you go through this, you won’t have to do it again.
As soon as your wallet synchronizes with the blockchain, you will be ready to start sending and receiving Bytecoin. Similarly, if you do not sync your wallet with the blockchain, you will not able to send or receive Bytecoin!
Your Bytecoin address, which is the address at which you can receive funds from other people, is the long string of random characters toward the top of your wallet. If you click on it, it will automatically be copied to your clipboard.
Now, you’re ready to start sending and receiving Bytecoin and as well as mining for Bytecoin.
------------------------------------------------Acquiring Bytecoin--------------------------------------------
While there are several ways to acquire Bytecoin, I will discuss the two most reliable methods here. In essence, you can either use your computer to mine for Bytecoin, or you can purchase Bytecoin directly from someone who has Bytecoin already.
As for using your computer to mine for Bytecoin, I would recommend creating an account on MinerGate.com and downloading its mining software. As was the case for your Bytecoin wallet, your anti-virus may recognize the software as a virus, but it’s not.
Once you load the software, you simply put in same e-mail address you used to create the account on MinerGate.com and start mining.
As far as CPU mining goes, you will want to use less CPU power than you computer currently has available. For example, my processor has six cores, so I typically only use 5 cores to mine. If you only have a dual-core processor, I would recommend you only use one of the cores to mine. Otherwise, you can cause your machine to overheat.
To monitor my system, including its core and GPU temperature, I use Open Hardware Monitor (i.e., http://openhardwaremonitor.org/)
As soon as you mine 100 Bytecoins, you can then transfer them directly to your wallet. Note: If you are only using a limited amount of your computer’s resources, this can take as long as one month, and there are calculators on MinerGate.com that will help you determine how long it should take.
--------------------------------------------------Bytecoin UK------------------------------------------------
If you want to start earning Bytecoin within a few hours, you can also mine on the Bytecoin UK pool (i.e., https://bytecoin.uk/#getting_started).
On its website, you can download a miner that has a Graphical User Interface (GUI) and see the commands you need to use other mining software. For example, I use Claymore's CPU miner, so I enter the following commands in command prompt:
NsCpuCNMiner64 -o stratum+tcp://bytecoin.uk:3333 -u YOUR_WALLET_ADDRESS -p x
By entering your wallet ID on its website, you can check your mining statistics and payment history. In addition, you can also configure it so that you will receive payouts for every 5 BCN you mine. Note: MinerGate requires you to mine 100 BCN before you can transfer the BCN to your wallet, whereas Bytecoin UK only requires you to mine 5 BCN for a payout.
If you don’t want to use your computer’s resources to mine Bytecoin, you can also purchase it directly from a seller.
In my experience, the most reliable way to buy Bytecoin is through eBay. There, you simply purchase Bytecoin from a seller who usually lists the methods by which he or she is willing to accept payment in the description of the post.
Typically, a seller will ask you to send your payment, as well as your Bytecoin address, to them via a message on PayPal.
As long as you send small amounts, your risk of being scammed is minimal, and personally, I have never been scammed this way.
So that’s it. Now, you’re ready to start using Bytecoin!

I've put together a post that has, what I think, is all the possible (english) information on SmartContainers' ICO out there

Okay, so this is going to be really long in terms of posts here. I actually have to cut out some info to make it under 40000 characters for reddit...
Typically in the market there are Currency and Utility coins. Profit-Share Tokens are relatively new, and while this ICO has 2 tokens, the profit share token is definitely the main attraction, as it's tied to a very, very promising company. This company is SmartContainers Group, and their tokens are SMARC (profit-share token) and LOGI (more on LOGI later).
“Smart Containers Group, formerly REP AG (Swiss registry of commerce, UID: CHE- 141.664.882), is a Swiss based, high tech company that provides the safest temperature controlled containers to transport sensitive pharma goods and food around the world. Our purpose is to secure sensitive goods and to make sure no compromised product is ever delivered to anyone.” - whitepaper


SmartContainers Group is a holding company for SkyCell.
SkyCell is the company Smart Containers Group uses to rent/sell their containers to clients around the world.
Our containers transport some of the most expensive and temperature-sensitive goods in the pharmaceutical industry. These goods need a particularly careful and accurate protection. Through our highly secure and efficient container design, we assure the best possible protection against temperature excursions. In combination with a cutting-edge technology, it enables us to provide containers with easy handling, maximum loading capacity and highest performance on the market.
More than 50 man-years of research and development poured into the creation of an unprecedented, highly efficient insulation. This cutting-edge technology reflects a maximum of radiation while minimizing heat conducting. It is the most patent protected insulation technology on the market.
The ingenious SkyCell R&D team invented a completely new, cooling technology, that stores five times more energy than traditional methods to keep the container at a steady temperature. Consequently, SkyCell containers are automatically recharged in a cooling chamber without any manual interference. Nothing can be mixed up since all parts are integrated and fixed.
The ingenious SkyCell R&D team invented a completely new, cooling technology, that stores five times more energy than traditional methods to keep the container at a steady temperature.
“oh, our product needs better cooling? Okay, let’s just invent a better cooling technology, no biggie”. Who heads that team, Rick Sanchez?
I asked about this tech during their AMA, here's what they said:
Cooling technology: Yes, our containers are state of the art. Nico has developed a cooling material that freezes at 5.5°C. So if you put it in a cooling chamber that has a lower temperature, it automatically freezes and if the temperature is higher it melts. Basically, the system works like a huge ice cube that is empty in the middle. The centre of the ice cube has a steady temperature of 0° until at least 1 side of the ice cube has melted. It's the same principle for SkyCell containers, but at 5.5°C
The patented-in house developed cooling technology stores five times more energy than traditional methods to keep the container at a consistent temperature. After use, they are ‘recharged’ in a cooling chamber without any need for manual intervention, increasing productivity of the business and reducing cost.
I’ve forgotten to mention something so far about their product [the containers]. They’re literally (not figuratively, literally) the most advanced container ON EARTH.
From their ICO FAQ: Where do you position yourself compared to Envirotainer? Envirotainer is the number one container company with the largest container fleet today. We are currently fourth globally, but we reached this position in less than 5 years operating in this space. SkyCell containers have been tested and shown to be technologically superior to Envirotainer containers (5x more runtime, up to 35% lighter) which translates into safer pharma distribution and cost savings as well as a reduced CO2 footprint.
We are currently fourth globally, but we reached this position in less than 5 years operating in this space.
Another thing that’s pretty impressive, 4th largest company in their entire field… after just 5 years… but back to the main point of that statement: “SkyCell containers have been tested and shown to be technologically superior to Envirotainer containers (5x more runtime, up to 35% lighter) which translates into safer pharma distribution and cost savings as well as a reduced CO2 footprint.”.
Watching a video from a blockchain conference in Switzerland, I got a fair bit of info from the CEO, Richard. I’ll be quoting him in that video a few times in this post, and here’s the first: “In my industry, we talk about how many shipments go wrong - and the average is 8.5%. So for 8.5% of pharma shipments for example, the [proper] temperature is not maintained. In our case [with Smart Containers], it’s less than 0.1%. That’s 75 times better. Richard also speaks in this video about how they will be able to eliminate the amount of shipments happening every year, due to the decentralized nature of this whole system, there will be less need to send packages to places far from their end destination, to make the delivery easier on the shipping side. We’ve all had packages come from across the ocean, only for it to fly 1500 Km past us to be shipped back our way next week…


”There are 200 documents are required, or exchanged, to make one shipment happen… we estimate we can bring this down to 8” Richard Ettl, CEO
Logistics is an old industry. it started out on paper, moved through the fax, early ages of the information era, early email, current email, and is now ready to move onto the blockchain.
“By using blockchain technology, we can decentralize logistics and create autonomous containers – container 4.0. This container will know who’s renting it, when the contract ends and when to invoice the customer. That’s why we’ve created the LOGI CHAIN platform. It allows us to create a seamless, fully integrated, digital logistics process that everyone can use for free.” - Richard Ettl, CEO
“Well-established processes often generate inefficiencies that we simply accept. And of course everyone knows change is painful. But at Smart Containers, we see things differently. Change is the only way to improve. We think that every process should not only be optimized but redefined and redesigned. Logistics today is highly centralized. It’s incredibly inefficient. So many wasted kilometers to huge warehouses.” Nico Ros, CTO
There will be more than one blockchain at play with this system as well. The info that people deserve to know will be available on a public blockchain like Ethereum, the weight, material safety data sheets, the storage conditions (which as said up above, 8.5% of pharma shipments have issues with, and Smart Containers brings that down to below 0.1%), as well as at the same time, the info that shouldn’t be public to everyone (Bills, invoices, etc) would be stored on a blockchain like Fabric or HyperLedger. LOGI will be the fuel for the LOGI Chain.
CMO Carla elaborating on LogiChain:
The LOGI project finds good echoes with logistics players but even more with blockchain infrastructures like NEM, EOS and NEO.
Emirates for once was enthusiastic about the project and definitely wants to join the foundation. As you know, the government of Dubai is focussing on applying blockchain asap to multiple industries.
We are also in exchange with ShipChain, who are running a similar project in the US. Our goal is to collaborate with a maximum of projects around the world.
The LOGI Chain Foundation will be set up in July, right at the end of the ICO. Dr. Fabian Schär, our valued Advisor, will be in charge of defining how the LOGI Chain Foundation will develop in the next 2-3 years. We think that we will be able to put out a PoC based on SkyCell until the end of the year.
We have not yet decided on which blockchain platform to build the LOGI CHAIN. We are highly delighted with NEM since they are already operative and offer a private and public blockchain on the same protocol.
One Chain to Connect them all - LOGI CHAIN
One platform to get all players up to speed, to handle all documents and permissions in one place. No more floods of emails. No more polluting the environment with senseless printing of documents. No more compatibility problems and clashes of individualized systems.
To show you how vast the amount of documents (and by this emails circulated) find a list of common documents needed for one air freight shipment below:
Documents of origin, Material safety sheet, Airway bill, Bill of lading, Transport order, Customs declaration documents & bills, Invoices, Product data sheet, Storage conditions, Transport conditions, Multiple service provider billings, Licenses, etc.
This adds up to the gigantic number of about 200 manually processed emails per shipment.
A combination of public and permission based chains will allow for all players in the ecosystem to store documents needed in the logistics processes. We are looking at multiple platforms to build the LOGI CHAIN on top including NEM, Fabric, Corda, EOS and NEO.


I’ll be using bits and pieces taken from their white paper and LinkedIn pages.
The Smart Containers team includes over 80 people, and is growing every year.
Richard Ettl - Co-Founder, CEO - LinkedIn
Richard wanted to know how things worked since he was a child. He has a passion for engineering and management. Growing up in Vienna, Austria and studying in Stanford USA and the University of Fribourg, Switzerland, he started his career at Bobst Group, a leading producer of packaging machines worldwide. In 2009, he decided to launch his own business together with his university friend Nico. After wide reaching scientific research and various proof of concepts, they founded today’s Smart Containers Group as well as SkyCell in 2012. Since then he has lead the companies to commercial success, seamlessly finding the right partners and investors at crucial points, as well as convincing more and more clients of the unrivaled benefits of the SkyCell offer
Nico Ros - Co-Founder, CTO - LinkedIn
Nico Ros, Chief Technology Officer & Co-Founder Nico is the mastermind behind Smart Containers Group and its technology. Growing up in Basel, Switzerland, he discovered his passion for mathematics very early on and therefore came to study mathematics, physics and engineering. Being a natural talent, he had already won prestigious architectural prizes during his studies and quickly became managing partner at ZPF an engineering company in Basel. He has constructed the most expensive buildings in Switzerland in collaboration with the famous architects Herzog & DeMeuron. Nico’s key strength lies not only in his state of the art engineering know how but also in his efficient management of teams, leading highly complex, multimillion projects to success. However, engineering alone did not suffice Nico. Having a passion for business and management, he decided to complete additional studies at the University of Fribourg, meeting Richard along the way. Everyone who meets Nico rapidly becomes aware of his sharp mind and his passion to invent new technologies. It is therefore not surprising, that both him and Richard ended up together where they are today.
Andreas Ernst - CFO - LinkedIn
Andreas is the true logistic finance expert in the company. He spent all his career in various finance roles of logistic service providers: from Swissair (today Swiss International Airlines), to Swissport (biggest ground service provider for airlines) where he filled the role as regional CFO for the Middle East and Africa. His last role before joining Smart Containers Group was CFO of Unitpool (now called Unilode), which is the largest independent air-freight container pooling company in the world.
Thomas Taroni - Head of IT - LinkedIn
Thomas is an IT-architecture mastermind. His first claim to fame is the creation of the largest media database, shared by all media houses in Switzerland: more than two million articles are uploaded every year, then queried and shared seamlessly and efficiently among multiple news companies. He founded his own IT company to design IT architectures focusing on process automation (eliminating paper and endless emails), and as a result won other clients (large banks, pharma companies and even publicly tendered government contracts). SkyCell became his client, when they needed a bespoke asset management system to track and trace their containers around the world. He joined SkyCell four years ago and since his tenure, has become the head of IT for all companies of Smart Containers Group.
Carla Bünger - CMO & Business Development Manager - LinkedIn
Carla is a marketing and sales expert. Building strong brands on solid foundations and convincing clients to buy its underlying products gives her huge satisfaction. She collected her experience through managing various international consumer brands, for companies such as Nestlé, Lindt and Coty. However, she discovered her passion for Blockchain technology roughly 18 months ago and has since been actively participating in the com - munity of Crypto Valley in Switzerland. The sheer endless application possibilities make her strive for more and she is drawing energy and enthusiasm from developing new business schemes around the subject. Her “can do” attitude helped to put together the high level advisory team around our ICO.


Strategic advisor: Oliver Bussmann, is CEO and Founder of Bussmann Advisory, former CIO of UBS and SAP as well as the President of the Crypto Valley Association. “our main advisor” - Richard
Strategic advisor: Marc Bettinger, Altcoin and Blockchain specialist and investor, Co-Host Altcoin Meetup Switzerland (Bitcoin Association Switzerland)
Strategic Advisor: Fabian Schär is Managing Director of the Center for Innovative Finance at the University of Basel. His research focus is on the potential and applications of blockchain. In addition, he works as a lecturer in blockchain technology at the University of Basel, the University of Applied Sciences in Business Administration Zurich (HWZ) and the University of Applied Sciences Northwestern Switzerland (FHNW).
Technology Partner: Lykke Corp. our highly trustworthy expert in smart contract programming and ICO execution. (Lykke also audited their ICO smartcontract)
Legal Advisor: Gabriela Hauser-Spuehler was part of the team of MME, the well-known law firm in the crypto space.
Communication Advisor: David Wachsman and Emma Walker from Wachsman PR, the crypto community’s most experienced PR agency.
Richard also states they hired a lawyer that worked on the Ethereum ICO, but I don’t know if it’s Gabriela up there or another person.


Min. investment = $500 USD for ICO, $5000 for presale (largest portion of supply), $250k for private sale.
There are two tokens as mentioned before: SMARC and LOGI. I’m more into SMARC because it’s safe (safe once the payouts start of course, as soon as a coin has a clear value like this, BTC moving up or down doesn’t matter to you), as well as obviously very attractive if you think of the long term profits.
Every year, the company’s annual shareholder meeting takes place, during which the shareholders will agree (or negotiate) on a proposal by the Smart Containers’ board about how much of the company profits is to be paid to the shareholders that year. 20% of that amount is taken, converted to ETH, and fairly distributed to the token holders.
Since the cofounders and all token holders will have aligned interests and incentives, we are all in a positive-sum-game. We do not want to use the ICO as a speculative springboard, but as way of funding innovation and change the world. Both Richard and Nico are committed for the long-term and not interested in a quick exit. Our aim is to use the collected funds to continue pushing the following business areas:
• Continue scaling of SkyCell in both B2B and B2C
• Establish FoodGuardians - the main goal if the ICO is to build and scale FoodGuardians
• Establish the of LOGI CHAIN Foundation
• Regularly evaluate organic scaling vs. M&A
• Evaluate IPO at relevant time
We are raising funds through an ICO to grow our container businesses in pharma and food. We push SkyCell from no. 4 to the no. 1 provider in the next 2-3 years.
The CEO in this video explains pretty easily why one would want to put money into this ICO over others:
“Why invest? [referring to SMARC] Simple question. It’s an up and coming company with revenue, multiple millions a year, most ICO’s have white papers…[we have much more than that].”
That's pretty clear. You can invest in random Xcoin ICO where they have some half-baked token that might see some level of adoption if it isn't just a cash grab, or you could invest in an actual multimillion-dollar company and be a part of it as it scales into what could potentially be a multibillion dollar entity.

The following is taken from the ICO, Legal, and Company FAQ

How will the profit share payouts work? 20% of dividends will be paid in ETH to all holders of SMARC tokens that are in circulation at the time of the payout. A given business year ends on 31st December each year with a general assembly held annually around mid-February. Therefore, dividend payout is expected around mid-March each year. In the event of a total sale of Smart Containers or the exit of one of its lines of business, the holders of SMARC tokens will receive a 20% participation of proceeds
Is there a future profit statement? No listed company can make an estimation or a commitment to a future return. To do so would neither be professional nor ethical. For Smart Containers, as with any company, profits may often depend upon a number of external factors, such as the general trust in blockchain technology. The question to be assessed is how fast a new disruptive technology can replace an old system. We believe that Smart Containers Group is well-positioned to facilitate this disruption, with a strong plan going forward and experienced team working to successfully implement blockchain technology in the supply chain. 5 years of industry experience, the 4th largest container fleet and a motivated team; that’s more than any idea whitepaper ICO.
What specific rights come with my investment? The SMARC token is a profit share token. When the company generates profits and the company’s general assembly approves a dividend payout, 20% of the defined funds attributed to dividends will be distributed proportionally to holders of SMARC tokens in circulation. In contrast, the LOGI token is a utility token that can be used to pay for transactions on the LOGI CHAIN, an open-source logistics platform for all stakeholders in the logistics field with the goal to create a seamless, fully integrated, digital logistics process.
Smart Containers will pay out a dividend to SMARC token holders. This would imply that the SMARC token is a security token. Are you compliant with financial regulation? Smart Containers tokens is not classified as a security in Switzerland under current law. This may be different in other jurisdictions such as the USA. Hence the SMARC token is not eligible for sale in certain jurisdictions. Our benchmark is the Modum token sale from June 2017. We have elected to use the same legal structure as it was accepted by regulators in Switzerland and well received by the ICO community and exchanges.
What is the vesting schedule for team and advisors tokens? Everyone will receive SMARC and LOGI tokens at the same time. Minting will occur at the end of the token sale. Advisors will have lock up periods depending on how many tokens they receive. Team members have a lock up period of 12 months.
Are SkyCell containers an approved ULD according to IATA regulations? SkyCell containers are exempt from the ULD rules by IATA. This has the huge advantage that, compared to our competitors, the SkyCell container can not only fly but can also leave the airport. Skycell containers are therefore a door-to-door solution. Our competitors’ containers, on the other hand, have to be unloaded at the airport and packed into a new transport unit in order to continue their journey from the airport to the final destination, increasing the risk of temperature excursion, and loss.
Are there financial statements? If so, are they audited, and by whom? Yes, there are financial statements for all our companies. They are audited by PricewaterhouseCoopers (PwC). To preserve our competitive advantage in the market, we have decided not to publish our financial figures online at this moment in time.
Are Modum and Smart Containers competitors? Modum and Smart Containers are not competitors, more future partners. Modum rents/sells sensors to track and trace shipments on temperature, whereas Smart Containers rents/sells the containers, in which products including sensors are put inside. Of course our containers have sensors that record data for quality control, but Smart Containers does not sell these data sets. In the end Modum and Smart Containers will address to the same clients - Smart Containers provides the container and Modum will put a sensor in it.
How many airlines fly SkyCell containers? In addition to our major partners, Emirates and CargoLux, more than 30 airlines fly SkyCell containers.
What destinations does SkyCell serve? SkyCell is a global company. We are shipping containers around the world and reach each pharma client within 24-48 hours. This is accomplished through our airline partners, that can fly ready-to-use containers to more than 150 airports.

Profit Sharing Mechanism

During the annual shareholder meeting, the shareholders in the form of the general assembly (Annual General Assembly) decide on a proposal by Smart Containers’ board regarding the usage of profit as recognized in the annual financial statements of Smart Containers in the form of distribution of dividends. Distribution of a dividend on shares shall be announced in the “Tokenholder Information” section of the Smart Containers website; such announcement shall include the date and time of the dividend payment and the dividend amount per ordinary share in USD as well as the ETH/USD exchange rate which shall become applicable, as derived from publicly available and reliable quotes. Within 20 business days of the date of the resolution passed by the Annual General Assembly regarding dividend payments to the shareholders of Smart Containers, Smart Containers will make available a Profit Share Amount to each authenticated Tokenholder equal to 20% (twenty percent) of all dividends agreed to being distributed per share to the shareholders, divided by the total number of issued SMARC Tokens (To further explain for clarity, all Tokenholders combined will receive an amount equal to 20% of the amount received by all shareholders combined.). SMARC Tokenholders shall receive these payments in ETH, at an average exchange rate specified by Smart Containers.


“Imagine your tomatoes tasting 1 day ‘fresher”.
One of the main reasons for the SMARC/LOGI ICO is to raise the funds to fuel the growth of FoodGuardians alongside SkyCell.
According to their CEO, SkyCell is constantly asked “can your containers be used for food?”, but there are several issues with shipping food and medicine together. This is where FoodGuardians comes in.
FoodGuardians offers the next generation of reusable containers and boxes to transport regionally and globally temperature sensitive food products.The combination of patented cooling technology, cutting edge insulation and Blockchain infrastructure allows to redefine the product’s freshness and traceability.
Our vision is to allow your local butcher to order your favorite steak directly from the producing farm and sending it straight to your grill party. (All without the buyer even leaving his home, let alone going to store)
Advantages of using FoodGuardians
Each FoodGuardians container can be tracked around the world on:
The phrase “Imagine your tomatoes tasting 1 day ‘fresher” has been used by the CEO a couple times, and is more or less the FoodGuardian slogan. This is referring to the fact that not only can FoodGuardian and SkyCell containers save cost, CO2, and man/brainpower, but they can also make shipments faster when combined with the blockchain (LOGI Chain) and Smart Contracts. when everything is accounted for at every second with almost as little room for human error as possible, things are far more efficient.
We are launching our first food application – we will announce a collaboration before June for a solution that can be used to ship overnight online fresh food to people homes and can be used to supply hospitals and restaurants as well.
FoodGuardians and SkyCell are two of the many possible use-cases for SmartContainers' tech:
"Other use cases. Yes indeed. We are just getting started!! However, it makes sense to focus on scaling SkyCell and FoodGuardians before starting something new. In the end we are a tech company. We have defined 7 use cases around the insulation technology. We have started with the most relevant 2 but will certainly continue."


SkyCell is looking to bring a business-to-consumer solution to market, that was developed and tested with one of the top 20 pharma companies in the world. The direct to patient market is estimated to increase to a 2.5 billion USD market in the future, with no other competition yet aside from styrofoam containers that are disposed of after one use. The SkyCell ONE can also be co-branded by a partner, such as a pharmacy chain that could rent it out for home delivery, business trips or even holidays.
The product is temperature stable for up to 72 hours, can be recharged passively in a fridge, or temp-controlled warehouse or truck. Currently it’s best in class for size and weight, but that’s probably down to there being no competition! Trials have been undergoing since June 2017 with an orphan drug product, and go live is expected in Q2 2018. - Cryptowithoutborders article
The SkyCell ONE container is showcased HERE
THIS could be a massive money maker. There is currently no direct pharma-2-consumer shipping service, because it really wasn’t profitable, or manageable on a central database. They can even sell this product to other supply chain entities to use. The direct to patient market is estimated to increase to a 2.5 billion USD market in the future, with no other competition yet, aside from styrofoam containers that get disposed of after a single

We are launching also additional sizes – so we are launching a very small box to ship pharma directly to patients' homes. Amazon just recently announced that they will postpone entering the pharma distribution space, as they do not have the technology to ship to patients homes in a temperature controlled manner. We are bringing this to market later this year. This will increase the convenience of patients and reduce the costs in the healthcare system.


I just finished listening to this podcast (20 minutes long, but you can skip the intro stuff to make it shorter of course). I’m now twice as excited as I was before. I’m going to type out a large chunk of the podcast. I’ll be paraphrasing slightly, so I don’t have to type every “uhh” or anything, plus he sometimes starts one sentence before finishing another.
“We have some prototypes, that we built, for example, for the Children’s Hospital here in Zurich, where we’ve designed a container that can transport living skin.” [Interviewer; “Wow.”] “So for young children that suffer skin diseases that could be almost fatal, like cancer, they grow this… patch of skin, and then that skin needs to be transported, and kept at body temperature so… roughly 37 degrees Celsius. There we designed them a box that did this for 10 days, autonomously.” [“That’s amazing…”] “Yeah, we did this because we wanted to learn how to interact and work with hospitals, this is a highly specialized application, and the next step could be organ logistics, because most of the organs today are transported on ice, because that’s the standard set in the 70’s, but studies have shown that if your transport certain tissue at room temperature, it is significantly better for the tissue than if you transport it on ice.”
I can guarantee you every major hospital on earth is going to want their hands on this container that can allow them to transport both living skin, and potentially organs in the future. The fact that in this day and age we’re still throwing people’s kidneys/lungs/etc in a bucket of ice is a little weird.
From the recent AMA:
Our Container BT5: The name stands for Body Temperature 5 L content. It transports skin grafts that was cultured for children with burn accidends. The temperature range is 37°c. Nico (our CTO) was so taken by this project, that he developped this container only for this purpose for a company calles Cutiss (a start-up from Zurich). We currently only have around 10 of these containers in use. It is not produced in on a large scale. We could market it, but have bigger opportunities to tackle first with the SkyCell one. You can only focus on 1-2 projects at a time. The BT5 is a beautiful project, but will need manpower to scale production and then manpower to market it.


Envirotainer, The leading company in this field, has only a matter of time before they’re overtaken. SmartContainer Group’s containers are proven to be superior (5x as efficient, 35% lighter, self-charging, etc, etc, read up above for the whole deal). According to the Googles, Envirotainer’s best year (2015) saw a profit of $50,000,000. It’s logical to assume that Smartcontainers will surpass them as the top dog, and at the same time be pulling in much more profit over time by serving both pharma, and the food industry (Envirotainer only does pharma). By accepting cryptocurrency payments, saving them a fair bit in fees from cross border payments, they’ll also net a small % more in profits annually.
I asked about the state of their competition. Turns out, Envirotainer (or more specifically the private equity firm that owns them) offered SmartContainers a buy out of $125m. This was one of countless offers they've turned down, because they believe they can scale the company to much further value. The firm selling Envirotainer has been trying to find a buying for the past 3 years, at $1b. No one will buy them, because anyone who knows their shit in that industry knows SmartContainers will overtake them in no time.
From April's AMA:
Our 2 biggest competitors are for sale. Envirotainer (biggest player) is owned by a Private Equity company that wants to sell it for 1 b USD. it already tries to sell for 3 years. SkyCell is considered a threat to the valuation of Envirotainer, since we are winning one client after the other from them. While Envirotainer is the largest player with a huge sales force and well established client contacts, they are still operating on an "old" technology. SkyCell is technology leader, has lighter containers, reduces CO2 emissions and is considered to be the future.
2 days ago, a private equity company requested a meeting to see the valuation of SkyCell and evaluate to buy. We have already been approached several times. We are treated as the bride in the market. However, Richard and Nico think we can scale the business much more before we should consider to sell. We are just getting started.
We have won 3 large accounts in Q1. Today we have 1200 containers. By the end of the year, it will be 2000. Our business plan estimates that SkyCell will be profitable in 2019. Therefore you can expect first dividends in Q1 2020.

Official Projections

Another redditor asked for "optimistic expectations for potential profits" during their ama, here was their answer:
How does a profit of 21 m USD on Smart Containers total in 2020 sound? This figure will then quadruple in 2021 to 76 m USD.
As you can see, this would mean that by 2021 tokenholders would not even have broken even yet. I myself am fine with this, i'm expecting to hold SMARC until the end (be it I die or the company sells, in which case i'll enjoy that fat exit payout). The potential gains from 2020-2030 are far more worth it to me than trying to make it in one year with heavy risk.
So why invest in this over a random shitcoin that might moon? If you're here to turn $1000 into $1m and get out by the end of the year, good luck, don't invest in smarc. If you're realistic and are aware that crypto will only be so volatile for so long, go ahead and think about putting a bit of your portfolio in something that will have actual value, lasting long after the shitcoins die. Crypto market could crash at any time, but that doesn't mean that SmartContainers as a company goes anywhere, nor their profits. I don't think I need to explain any further.


A 5 year old company, with over 100,000 collective hours of R&D put into their products, with currently just under 100 innovative patents, that is already the 4th largest of it’s kind in the world, with the top product in their field on earth, is doing an ICO that is fully backed by the Swiss government, with a token that is due 20% of all future shareholder payouts, as well as 20% of any potential exit profits (the company being purchased). They’re already this big, and you can benefit from both their success, and their expansion into new markets.
There’s nothing stopping SmartContainers Group/SkyCell/FoodGuardians from working with VeChain in the future either. Or Walton, or Wabi, Devery, OriginTrail, Ambrosus, all of em.

Should you invest in this? I sure am, and am very glad to even be offered the opportunity, but it’s up to you. Read through this post if you haven't yet, then click these links and decide for yourself. Don't go all in of course, since this is a profit share token, there is much less risk, therefore less short term reward. The long term reward is what we're looking at here, don't buy into the ICO and then complain that you aren't getting 1000% ROI payouts by year one.
