We recently had the opportunity to interview the VP of ViaBTC Group, Eddie Jiang. ViaBTC Group owns popular crypto exchange CoinEx and ViaBTC Pool. In this interview Eddie discusses being the first exchange to use BCH as the base currency, ViaBTC Pool and integrating with CoinEx, new features and ambassador program, and competing with other exchanges like Binance and Huobi. Please enjoy the interview below.
How come you decided to open up CoinEx to other cryptos other than just BCH?
Eddie Jiang: CoinEx is the world’s first exchange to implement Bitcoin Cash as a base currency. At that time, it was evident that there was a demand for BCH trading markets, and we are the first to explore this opportunity. It also shows our determination to support the BCH’s development.
As CoinEx is developing, our goal becomes bigger and we are aiming at the global market. We need to constantly improve our product diversification to meet the different needs of more users, so we open up to other cryptos. In the past six months, we have listed more than 50 new tokens. Up to now, we have listed 129 cryptos and 313 markets. Besides, in addition to spot trading, CoinEx also supports perpetual contract and other derivatives trading.
How does CoinEx integrate with the ViaBTC Pool?
Eddie Jiang: ViaBTC Group announced a strategic upgrade, which included a new organizational structure, product innovations and service improvements, on 30 May.
As part of the change, the Group has established three dedicated business units (BU): the financial services BU, consisting of ViaBTC mining pool and CoinEx exchange; the infrastructure services BU, including ViaWallet and Blockchain Explorer; and the ecological development BU, focusing on the research and development of public chain technology and the construction of the ecology.
After halving, the combination of mining and finance will become closer and closer. Investing in mining machines is like buying a Bitcoin option. Miners need more flexible financial products to maintain and increase the value of assets, or hedging services. Based on this judgment, the operations of ViaBTC mining pool and CoinEx exchange will be integrated in the future to realize the financial empowerment of the mining pool to meet the diverse financial needs of miners.
Features of this integrated product upgrade can be summarized as: “ The mining pool is the wallet, and the wallet is the transaction.” ViaBTC is the world first mining pool that has a wallet embedded in the mining pool account. Users do not need to transfer the mined coins, and can realize the function of coin exchange within the wallet. For example, they can directly convert the mined coins into USDT to pay electricity bill. What’s more, users can store, deposit and withdraw their revenue, and transfer assets to CoinEx at any time without charge, as well as complete other operations on the exchange, such as purchasing wealth management products for asset preservation and appreciation. In addition, we also provide hedging services. All of the above functions can be completed in one stop in the mining pool, without the need to transfer assets between different platforms.
The exchange empowers the mining pool, and the mining pool will further bring more traffic and resources to the exchange. The two complement each other and development coordinately.
CoinEx has recently added many new features. Can you talk about what new updates were made to the platform and why you made them?
Eddie Jiang: We have always attached great importance to the development of overseas markets since our establishment, and one of our major goals this year is to cover at least 10 different languages speaking markets.
To realize this and to meet the needs of more users worldwide, CoinEx has been continuously optimizing and upgrading its operating strategies, products and services. Our product diversifications are constantly improving. As I said before, we have launched leverage trading, perpetual contract trading, and wealth management products in addition to just spot trading. However, we don’t ignore the importance of spot trading. More mainstream, popular, and high-quality tokens have been listed, and up to now, there are 129 tokens and 313 trading pairs on CoinEx.
During the epidemic, we have never slowed down our development. Lacking of the OTC service has always been a shortage for CoinEx. In March, we partner with Simplex to integrate the first fiat onramp to our platform. People now can buy crypto with their credit cards, which lowers the threshold for more people to enter the crypto world. Moreover, we announced global strategic partnership with Matrixport to provide people with large amount of fiat to crypto needs the OTC service. These newly launched services also help to attract more users.
At the same time, CoinEx has been launched in Arabic, Italian, English, Japanese, Russian, Korean and other 16 languages. Earlier we also carried out product upgrades, making the UI and function sections clearer.
In terms of operations, we launched an upgraded CoinEx Ambassador program in March. To best utilize each ambassador’s personal strengths, there are four categories of CoinEx Ambassador with different responsibilities, namely Referral Ambassador, Marketing Ambassador, Operation Ambassador, and Business Ambassador, which will expand our brand’s exposure and help CoinEx grow into a more international exchange platform.
From March until now CoinEx has seen a 100% increase in user registrations. Why is that and are you able to see where they are coming from?
Eddie Jiang: Because of the efforts mentioned above, in 2020, we’ve seen an exponential increase in activity in just the past few months alone. In this year alone, CoinEx’s daily registered users increased by 100%. These new users mainly come from markets such as the Middle East, Asia Pacific, and more.
Interestingly, we saw an uptick in traffic from the Middle East in March. User growth in Southeast Asia also picked up significantly, newly registered users increased by 133.6% in April.
With Binance, BitMex, Huobi, Bybit, and Deribit, controlling most of the crypto futures and options markets, where do you see CoinEx fitting in? How do you plan to capture market share from these large exchanges?
Eddie Jiang: We won’t compete with others. We focus on ourselves to improve products and our goal is to be better than yesterday.
Our pace is solid and steady, instead of focusing on temporary heat and flow. We have always attached great importance of spot trading, and we are committed to be responsible for users’ investment. We have set up CoinEx Institution, which is dedicated on project research. A listing committee consist of core team members review and vote on projects recommended by the CoinEx Institution. In this way, fraud projects are avoided as much as possible.
Besides, we will focus on niche areas with great potential. For example, Southeast Asia and the Middle East. CoinEx can serve users in those countries well by providing a platform with rich cryptos to trade, and will pay more efforts on refined operations in different countries.
Moreover, CoinEx has a very complete ecosystem. Financial services, infrastructure, and ecological development, the three business units complement each other. The infrastructure BU is our cornerstone and is positioned as a defensive product; the financial service BU is a cash cow and is positioned as an aggressive product; the ecological development BU focuses on the public chain ecology and is the future infrastructure.
What is the geographical breakdown of the CoinEx userbase?
Eddie Jiang: The current proportion of CoinEx’s overseas users has reached 80% of the total registered users, and mainly in Australia, Southeast Asia, North America, Middle East and South Korea.
Do you have plans to focus on any certain jurisdictions? How will you do that?
Eddie Jiang: When we evaluate regions, two things matter: policy and potential.
Whether an exchange’s business expansion in a region is smooth or not largely depends on the region’s policies. If the region is not very friendly towards cryptocurrency or has repeated attitudes, there will be more difficulties and the cost will be much higher.
For a region’s development potential, we need to think about the demand and market development status. South Korea, Southeast Asia, the Middle East and other regions are all areas with good potential for cryptocurrency development. Compared with Europe and America, policy risks in these countries are lower, and the supervision mechanism is relatively complete. The public has a high degree of awareness of cryptocurrencies. Besides, some regions or countries have inflation problems due to political and economic reasons.
CoinEx will continue to focus on the Middle East and South Asia, which are relatively niche. India has just lifted ban on cryptocurrency trading this year, and there are many cryptocurrency investors in Indian. CoinEx can serve them well by providing a platform with rich cryptos to trade. More people in the Middle East are interested cryptos, especially in countries that are subject to economic sanctions or high inflation. For those people, cryptocurrencies are one of the best choices for asset preservation.
Since the CoinEx Ambassador program launched in March, it has been almost three months. We are conducting the second round of ambassador recruitment. This time, we will use the power of ambassadors to expand our recruitment coverage and strive to attract more crypto enthusiasts from all over the world to grow together with CoinEx. Moreover, we will launch the National Expansion plan and leverage on the CoinEx and ViaBTC mining pool resources, to further explore the Russian market. At the market level, we will make more PR efforts in local markets, and start refined operations.
What is CoinEx Chain and CoinEx DEX?
Eddie Jiang: CoinEx Chain is a public chain built on the Tendermint consensus protocol and the Cosmos SDK. It consists of three dedicated public chains parallel to each other. Among these three chains, CoinEx DEX meets the most basic needs of DeFi for token issuance, transfer, and transactions. The Smart Chain is designed to meet the needs of complex financial scenarios and delivers programmable cash. The Privacy Chain facilitates privacy and security.
On November 11, 2019, we took the lead in launching the Mainnet of CoinEx DEX. CoinEx DEX is the world’s first public chain dedicated to decentralized transactions. Users can easily manage their digital assets on it.
CoinEx DEX can fully satisfy the following conditions: users have private keys at their own disposal; transfers and transactions are all completed on-chain, which is 200% transparent and checkable; the issuance, transfer, and transaction of tokens do not require review or permission; the community governance and operation is decentralized, similar to EOS, and validators are introduced to the community ecosystem construction and governance. There are currently 41 validators.
It also has extreme performance. TPS reaches as high as 10,000 and transactions are confirmed within seconds. The transaction fee, 0.0001 US dollars for each transaction, is negligible.
Third, it’s simple and easy to use. The new operation interface design helps beginners get started quickly; with the one-click token issuing module, users only need to fill in a few items to issue tokens; the built-in automated market-making module guarantees liquidity.
How will CoinEx DEX improve the decentralized exchange space that has been unable to gain much adoption?
Eddie Jiang: There are many challenges and difficulties facing centralized exchanges. The first difficulty is security. Security is a huge concern for CEXs. Over the last 10 years, hackers have stolen more than $1.5 billion from centralized exchanges. In fact, research groups estimate that hackers stole somewhere between $950 Million and $1 Billion from centralized exchanges in 2018 alone. There were also incidents of coin thefts in other exchanges in 2019. Many exchanges, such as Mt. Gox, Youbit, were forced to file for bankruptcy and shut down as a result of hacks.
The second is high management costs. Centralized exchanges need to list a large number of cryptocurrencies and each of them have different trading pairs. That entails huge efforts in development and maintenance and, thus, high management costs.
The last is global policies. Cryptocurrency is faced with different regulatory policies in different countries. Every time a centralized exchange enters a country, it needs to adapt itself to local regulatory policies for compliance. This is a holdback for the exchange’s rapid market expansion globally. Such adaptation will also bring a huge learning cost for the exchange team.
Obviously, these problems can be well solved by DEX. CoinEx DEX is a true DEX with full open source and full community governance, as well as without depending on official nodes, websites, wallets, etc. On DEX, users are able to in charge of their own private keys and assets all by themselves. Their assets are more safe and secure. Transfers and transactions are all completed on-chain, which is 200% transparent and checkable; and the issuance, transfer, and transaction of tokens do not require review or permission. What’s more, CoinEx DEX provides a great and convenient user experience.
How will CoinEx Chain and DEX help the crypto industry as a whole?
Eddie Jiang: The public chain is the cornerstone of the blockchain industry. CoinEx Chain has the parallelism of multiple dedicated public chains, each of which performs its own functions, by cross-chaining for both high performance and flexibility.
CoinEx Chain is committed to building the next generation of blockchain financial infrastructure. It is a more complete ecosystem built around the DEX public chain. The DEX public chain is a dedicated public chain developed specifically for token issuance and trading and the biggest improvement on trading speed, so it only supports the necessary functions, not smart contracts.
But smart contracts are the foundation for building more complex financial applications. Outside the DEX public chain, CoinEx Chain also includes a Smart Chain that supports smart contracts.
Moreover, as privacy issues on the current blockchain have been criticized, it is one of the core tasks of CoinEx Chain to safeguard users’ privacy. Similar to the Smart Chain, the Privacy Chain specifically supports transaction privacy protection. With cross-chain circulation, it can improve the privacy characteristic of the entire CoinEx Chain ecosystem.
Nowadays, 1.7 million people in the world have no bank accounts; however, among them, two thirds are smartphone users with huge demands for financial services. The public chain will empower DeFi applications’ development and popularization, not only help more companies to seize the huge market opportunity, but also to bring lasting transformations and improvements in people’s lives.
With so many crypto exchanges, what is the future outlook of CoinEx when it comes to the crypto exchange space?
Eddie Jiang: It has been nearly 3 years since CoinEx has been launched, but it’s quite young for an entrepreneurial team. We have seen too many projects’ failures due to governance issues. CoinEx has a very elite team with high technical and management capabilities. In terms of business, CoinEx has gradually developed with diversified business and a complete ecosystem. It’s clear that the market will still grow very fast in the future, and the market size is still very large. We will continue to improve our products, put more efforts in marketing and operations, as well as look for more high-quality projects, to increase the number of users and transactions on the platform. Lay a solid foundation, and I’m sure the time will come for us to shine.
What updates is the CoinEx team most excited for?
Eddie Jiang: We are very excited about the National Expansion Plan which will be launched later this year. It is an important part in CoinEx’s globalization strategy. We will actively explore some new markets while consolidate the original ones. CoinEx will set aside 10 million US dollars to set up a “Pioneer Fund” to support this plan. This fund will be used to support local cryptocurrency projects and promote the development of the local cryptocurrency communities through investment or cooperation. Our goal this year is to invest in projects and communities that are conducive to expanding the CoinEx ecosystem in countries with high development potential.

(CEX vs DEX) vs HEX

A hybrid crypto exchange is a platform that provides users with access to their private keys and aims to solve the scalability issues of decentralized exchanges.
*Disclaimer: I don’t insist that one have to store 100% of the portfolio on any kind of exchange.

Why is it called Hybrid exchange?
Hybrid crypto exchanges combine the pros of Centralized crypto exchanges and Decentralized crypto exchanges. The hybrid concept allows for certain cons to be remedied by implementing the advantages of the opposite.

What are Centralized and Decentralized exchanges?
Centralized(CEX) crypto exchanges provide massive volatility with the help of market-making activities.
Occasional fiat gateways for its users, so everyone could quickly cash out gainings.
Besides, substantial centralized crypto exchanges have a higher trust score within the community.

Decentralized(DEX) crypto exchanges provide a solution to the security issues by letting users be in control of their private keys. This feature is a part of the real decentralization of trust philosophy, which is essential for the whole crypto economy.

DEX vs CEX





On the one hand, DEX’s provide higher security and privacy for its users, but those aren't the only things we are looking for. On the other hand, CEX’s, as I told earlier, have a higher trust score, so what does this mean exactly?


But is their royalty deserved?
“I definitely hope centralized exchanges go burn in hell as much as possible,” Vitalik Buterin stated in 2018. In particular, he thinks there’s no reason some projects need to pay $10 to $15 million(as per 2018) in listing fees to let people trade their tokens on centralized exchanges.
This feels like a blood diamonds issue in the diamond industry. Most of those platforms were built on lies, some of them are currently building themselves out on falsehoods.

CEXs have to be regulatory compliant, it’s impossible to be obedient without registering a company, submitting documents for proof of identity, etc. Most of the legal registries are opened to the public. Hence the founders are publicly known individuals. Besides, there is no need to hide while you are compliant and not involved in illegal activities.



If you are new to this industry, or do not want to understand the intricacies of blockchains and came here to trade Bitcoin, I advise you to use a CEX.
But If you came here for the tech, you will enjoy reading this more.

What is the hybrid crypto exchange approach?
Not so long ago, I decided to dive into the topic of hybrid exchanges as a potential game-changer in the cryptocurrency industry.
The hybrid exchange philosophy builds on the strengths of decentralized and centralized exchanges. During my research, I came across a curious example - NEXT.exchange
To further simplify the process of understanding the principles of hybrid exchanges, I propose to consider this topic by case. It’s worth noting that there is much to contemplate in regards to hybrid exchange platforms, their solutions and approaches may vary. There are also not many out there.

DEX pros within NEXT:

Essentially NEXT.chain will be used by the exchange as an open database that stores information about all transactions and tokenized assets (assets created on NEXT.chain are dubbed 00X standard) within the exchange.
To maintain the blockchain, investors will deploy 100 master nodes during the first year (79 out of 100 are already functioning).





CEX pros within NEXT:



It’s important to note that NEXT is just at its start, and will be releasing a huge update dubbed 2.0 (after a testing period with its community), so if hybrid cryptocurrency exchanges are interesting to you - then this is definitely one to keep an eye out for.

Summing up
Recently, the industry of centralized crypto-exchanges is literally filled with scammers.
Teams of second-rate centralized exchanges "draw" trading volumes and even IEO results. Unfortunately, many blindly believe them. This is going to be a massive problem in the future, more important than you can imagine. Those scam exchanges will become more prominent and will swindle more people, this will lead to a severe outflow of defrauded people from the industry, which can not afford it.
Hybrid cryptocurrency exchanges are a new trend that I think can improve the whole industry.
Not all hybrid exchanges have their own blockchain, NEXT was considered as the project most suitable for the description of a hybrid cryptocurrency exchange.
Don't FOMO and don't hesitate to do your own researches before depositing funds on the exchange wallets or participating in an IEO.

November BTC Fork - The Facts

Update 2: THE NOVEMBER SEGWIT2X HARDFORK HAS NOW BEEN CANCELLED! :D
Update: Thank you for your appreciation on this article. I decided to publish it on Medium.  
You can find the article on this link.
 
Existing Article:
With less than a dozen days left before the SegWit2X fork, I thought I'd start gathering some facts before I start forming personal opinions and speculative conclusions. I refer to the SegWit1X chain as 1X and the SegWit2X chain as 2X for simplicity, and I have looked for very simple facts and safe assumptions. Here are the dots that I gathered:  
 
• Fork at Block 494,784. Approximate time = 16th of November - see Reference 6 for exact time.  
 
The New York Agreement: The NYA involved parties representing about 83% of the then hashing power who all agreed to both hardforks - one for SegWit and another for an increased block size of 2MB (2X) within 6 months of the former. Further details in reference 1.  
 
• It is safe to assume that miners will only mine the most profitable chain (possibly several chains in differing proportions).  
• If whales pump a single chain it will gain more value. If this happens, miners will be more inclined to mine that particular chain only. This will result in the other chain(s)potentially losing overall mining attractiveness.  
 
1X will continue to have a 1MB block and SegWit;  
2X will have a 2MB block and SegWit;  
Bitcoin Cash (Just for info right now) currently has an 8 MB block with NO SegWit;  
 
Current Price Status (Futures) on BitFinex: 2X/BTC = 0.17; 1X/BTC = 0.83  
 
Current Mining Status: 2X = Around 85% of blocks are signalling for 2X.  
It seems only a few mining pools including Slush Pool, F2Pool and Kano CKPool are not signalling Segwit2X. All Antpool (Jihan Wu) owned pools are signalling for Segwit2X and will likely continue to do so up to the fork. It is not clear if any other pools from the Segwit2X signalling group will change their minds in the meantime.  
 
Lower mining power chain: Likely to be 1X. Fees likely to be extremely high as not many miners. Difficulty adjustment could take a few weeks, if not months. Until then it will be very difficult to transfer funds. [It may be better to keep BTC on an exchange before fork, to ease liquidity cost/time if you want to sell either of the coins immediately]  
 
Double-spending: Miners (from 2X) will have an ability and incentive to double-spend on the minority chain (lower mining power chain). If you have huge mining power, you can allocate some of it to just double-spend on the minority chain. Some people will possibly lose confidence in the minority chain as a result.  
 
Replay-Protection: Neither 1X nor 2X currently have replay protection.  
 
Exchanges:
  1. Bitfinex: original chain is “BTC”, SegWit2x chain is “B2X”  
  2. BitMEX: Original chain is BTC  
  3. Bitstamp: Unknown  
  4. GDAX & Coinbase: hash power and market cap decides which chain is “BTC”  
  5. Kraken: Unknown  
  6. HitBTC: original chain is “BTC”, SegWit2x chain is “B2X”  
  7. CoinsBank: Original chain is BTC  
  8. CEX.IO: original chain is “BTC”, SegWit2x chain is “B2X”  
  9. Gemini: hash power decides which chain is “BTC”  
  10. Coinfloor: Unknown  
  11. BTCC (Updated on Twitter): BTCC will consider which of 1MB and 2MB to name as #bitcoin based on market feedback and adoption.  
Further details in reference 4.  
 
The OPINIONs section
Vinny Lingham's opinion: 2X will outcompete 1X.  
 
Enter Bitcoin Cash: A review by Ryan X. Charles who has incorporated some of Vinny Lingham's quotes, states the following:  
 
a. BCH is a fork of BTC with same PoW, but with improved Difficulty Adjustment Algorithm (DAA). BCH cannot die, but 1X and 2X could both die. If whales shift most of their holdings to BCH (or another coin), that would incentivise the miners to mine BCH (or another coin) instead of 1X and 2X. Both 1X and 2X would lose their mining power; however Core would release an emergency update to software adding DAA like BCH (or another coin). Thus, 1X would survive, and 2X (which might not get DAA) would die.  
 
b. If 2X continues to be the dominantly mined chain, 1X will be forced to launch an emergency update to their PoW with DAA. There could be fighting between the two chains, and as a result a struggle to become dominant potentially causing altcoins to flourish.  
 
My observations
BCH is upgrading their EDA (Emergency Difficulty Adjuster) on Nov 13. See website. This will lead to reduced volatility in BCH - likely making it more attractive to more long-term miners.  
 
Mining profitability: It is currently almost equally profitable to mine either BTC or BCH.  
 
• What to keep and eye on before the fork to judge yourself where the fate of BTC is heading.  
  1. Mining signalling distribution
  2. DAA: 1X or 2X software updates to implement Difficulty Adjustment Algorithms
  3. Futures price before fork
  4. Significant whale movement

A Beginners Guide to Bitcoin, Blockchain & Cryptocurrency

As cryptocurrency, and blockchain technology become more abundant throughout our society, it’s important to understand the inner workings of this technology, especially if you plan to use cryptocurrency as an investment vehicle. If you’re new to the crypto-sphere, learning about Bitcoin makes it much easier to understand other cryptocurrencies as many other altcoins' technologies are borrowed directly from Bitcoin.
Bitcoin is one of those things that you look into only to discover you have more questions than answers, and right as you’re starting to wrap your head around the technology; you discover the fact that Bitcoin has six other variants (forks), the amount of politics at hand, or that there are over a thousand different cryptocurrencies just as complex if not even more complex than Bitcoin.
We are currently in the infancy of blockchain technology and the effects of this technology will be as profound as the internet. This isn’t something that’s just going to fade away into history as you may have been led to believe. I believe this is something that will become an integral part of our society, eventually embedded within our technology. If you’re a crypto-newbie, be glad that you're relatively early to the industry. I hope this post will put you on the fast-track to understanding Bitcoin, blockchain, and how a large percentage of cryptocurrencies work.

Community Terminology

Altcoin: Short for alternative coin. There are over 1,000 different cryptocurrencies. You’re probably most familiar with Bitcoin. Anything that isn’t Bitcoin is generally referred to as an altcoin.
HODL: Misspelling of hold. Dank meme accidentally started by this dude. Hodlers are much more interested in long term gains rather than playing the risky game of trying to time the market.
TO THE MOON: When a cryptocurrency’s price rapidly increases. A major price spike of over 1,000% can look like it’s blasting off to the moon. Just be sure you’re wearing your seatbelt when it comes crashing down.
FUD: Fear. Uncertainty. Doubt.
FOMO: Fear of missing out.
Bull Run: Financial term used to describe a rising market.
Bear Run: Financial term used to describe a falling market.

What Is Bitcoin?

Bitcoin (BTC) is a decentralized digital currency that uses cryptography to secure and ensure validity of transactions within the network. Hence the term crypto-currency. Decentralization is a key aspect of Bitcoin. There is no CEO of Bitcoin or central authoritative government in control of the currency. The currency is ran and operated by the people, for the people. One of the main development teams behind Bitcoin is blockstream.
Bitcoin is a product of blockchain technology. Blockchain is what allows for the security and decentralization of Bitcoin. To understand Bitcoin and other cryptocurrencies, you must understand to some degree, blockchain. This can get extremely technical the further down the rabbit hole you go, and because this is technically a beginners guide, I’m going to try and simplify to the best of my ability and provide resources for further technical reading.

A Brief History

Bitcoin was created by Satoshi Nakamoto. The identity of Nakamoto is unknown. The idea of Bitcoin was first introduced in 2008 when Nakamoto released the Bitcoin white paper - Bitcoin: A Peer-to-Peer Electronic Cash System. Later, in January 2009, Nakamoto announced the Bitcoin software and the Bitcoin network officially began.
I should also mention that the smallest unit of a Bitcoin is called a Satoshi. 1 BTC = 100,000,000 Satoshis. When purchasing Bitcoin, you don’t actually need to purchase an entire coin. Bitcoin is divisible, so you can purchase any amount greater than 1 Satoshi (0.00000001 BTC).

What Is Blockchain?

Blockchain is a distributed ledger, a distributed collection of accounts. What is being accounted for depends on the use-case of the blockchain itself. In the case of Bitcoin, what is being accounted for is financial transactions.
The first block in a blockchain is referred to as the genesis block. A block is an aggregate of data. Blocks are also discovered through a process known as mining (more on this later). Each block is cryptographically signed by the previous block in the chain and visualizing this would look something akin to a chain of blocks, hence the term, blockchain.
For more information regarding blockchain I’ve provided more resouces below:

What is Bitcoin Mining

Bitcoin mining is one solution to the double spend problem. Bitcoin mining is how transactions are placed into blocks and added onto the blockchain. This is done to ensure proof of work, where computational power is staked in order to solve what is essentially a puzzle. If you solve the puzzle correctly, you are rewarded Bitcoin in the form of transaction fees, and the predetermined block reward. The Bitcoin given during a block reward is also the only way new Bitcoin can be introduced into the economy. With a halving event occurring roughly every 4 years, it is estimated that the last Bitcoin block will be mined in the year 2,140. (See What is Block Reward below for more info).
Mining is one of those aspects of Bitcoin that can get extremely technical and more complicated the further down the rabbit hole you go. An entire website could be created (and many have) dedicated solely to information regarding Bitcoin mining. The small paragraph above is meant to briefly expose you to the function of mining and the role it plays within the ecosystem. It doesn’t even scratch the surface regarding the topic.

How do you Purchase Bitcoin?

The most popular way to purchase Bitcoin through is through an online exchange where you trade fiat (your national currency) for Bitcoin.
Popular exchanges include:
  • Coinbase
  • Kraken
  • Cex
  • Gemini
There’s tons of different exchanges. Just make sure you find one that supports your national currency.

Volatility

Bitcoin and cryptocurrencies are EXTREMELY volatile. Swings of 30% or more within a few days is not unheard of. Understand that there is always inherent risks with any investment. Cryptocurrencies especially. Only invest what you’re willing to lose.

Transaction & Network Fees

Transacting on the Bitcoin network is not free. Every purchase or transfer of Bitcoin will cost X amount of BTC depending on how congested the network is. These fees are given to miners as apart of the block reward.
Late 2017 when Bitcoin got up to $20,000USD, the average network fee was ~$50. Currently, at the time of writing this, the average network fee is $1.46. This data is available in real-time on BitInfoCharts.

Security

In this new era of money, there is no central bank or government you can go to in need of assistance. This means the responsibility of your money falls 100% into your hands. That being said, the security regarding your cryptocurrency should be impeccable. The anonymity provided by cryptocurrencies alone makes you a valuable target to hackers and scammers. Below I’ve detailed out best practices regarding securing your cryptocurrency.

Two-Factor Authentication (2FA)

Two-factor authentication is a second way of authenticating your identity upon signing in to an account. Most cryptocurrency related software/websites will offer or require some form of 2FA. Upon creation of any crypto-related account find the Security section and enable 2FA.

SMS Authentication

The most basic form of 2FA which you are probably most familiar with. This form of authentication sends a text message to your smartphone with a special code that will allow access to your account upon entry. Note that this is not the safest form of 2FA as you may still be vulnerable to what is known as a SIM swap attack. SIM swapping is a social engineering method in which an attacker will call up your phone carrier, impersonating you, in attempt to re-activate your SIM card on his/her device. Once the attacker has access to your SIM card he/she now has access to your text messages which can then be used to access your online accounts. You can prevent this by using an authenticator such as Google Authenticator.

Authenticator

The use of an authenticator is the safest form of 2FA. An authenticator is installed on a seperate device and enabling it requires you input an ever changing six digit code in order to access your account. I recommend using Google Authenticator.
If a website has the option to enable an authenticator, it will give you a QR code and secret key. Use Google Authenticator to scan the QR code. The secret key consists of a random string of numbers and letters. Write this down on a seperate sheet of paper and do not store it on a digital device.
Once Google Authenticator has been enabled, every time you sign into your account, you will have to input a six-digit code that looks similar to this. If you happen to lose or damage the device you have Google Authenticator installed on, you will be locked out of your account UNLESS you have access to the secret key (which you should have written down).

Hardware Wallets

A wallet is what you store Bitcoin and cryptocurrency on. I’ll provide resources on the different type of wallets later but I want to emphasize the use of a hardware wallet (aka cold storage).
Hardware wallets are the safest way of storing cryptocurrency because it allows for your crypto to be kept offline in a physical device. After purchasing crypto via an exchange, I recommend transferring it to cold storage. The most popular hardware wallets include the Ledger Nano S, and Trezor.
Hardware wallets come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key as well as any other sensitive information in a safety deposit box.
I know this all may seem a bit manic, but it is important you take the necessary security precautions in order to ensure the safety & longevity of your cryptocurrency.

Technical Aspects of Bitcoin

TL;DR
  • Address: What you send Bitcoin to.
  • Wallet: Where you store your Bitcoin
  • Max Supply: 21 million
  • Block Time: ~10 minutes
  • Block Size: 1-2 MB
  • Block Reward: BTC reward received from mining.

What is a Bitcoin Address?

A Bitcoin address is what you send Bitcoin to. If you want to receive Bitcoin you’d give someone your Bitcoin address. Think of a Bitcoin address as an email address for money.

What is a Bitcoin Wallet?

As the title implies, a Bitcoin wallet is anything that can store Bitcoin. There are many different types of wallets including paper wallets, software wallets and hardware wallets. It is generally advised NOT to keep cryptocurrency on an exchange, as exchanges are prone to hacks (see Mt. Gox hack).
My preferred method of storing cryptocurrency is using a hardware wallet such as the Ledger Nano S or Trezor. These allow you to keep your crypto offline in physical form and as a result, much more safe from hacks. Paper wallets also allow for this but have less functionality in my opinion.
After I make crypto purchases, I transfer it to my Ledger Nano S and keep that in a safe at home. Hardware wallets also come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key in a safety deposit box.

What is Bitcoins Max Supply?

The max supply of Bitcoin is 21 million. The only way new Bitcoins can be introduced into the economy are through block rewards which are given after successfully mining a block (more on this later).

What is Bitcoins Block Time?

The average time in which blocks are created is called block time. For Bitcoin, the block time is ~10 minutes, meaning, 10 minutes is the minimum amount of time it will take for a Bitcoin transaction to be processed. Note that transactions on the Bitcoin network can take much longer depending on how congested the network is. Having to wait a few hours or even a few days in some instances for a transaction to clear is not unheard of.
Other cryptocurrencies will have different block times. For example, Ethereum has a block time of ~15 seconds.
For more information on how block time works, Prabath Siriwardena has a good block post on this subject which can be found here.

What is Bitcoins Block Size?

There is a limit to how large blocks can be. In the early days of Bitcoin, the block size was 36MB, but in 2010 this was reduced to 1 MB in order to prevent distributed denial of service attacks (DDoS), spam, and other malicious use on the blockchain. Nowadays, blocks are routinely in excess of 1MB, with the largest to date being somewhere around 2.1 MB.
There is much debate amongst the community on whether or not to increase Bitcoin’s block size limit to account for ever-increasing network demand. A larger block size would allow for more transactions to be processed. The con argument to this is that decentralization would be at risk as mining would become more centralized. As a result of this debate, on August 1, 2017, Bitcoin underwent a hard-fork and Bitcoin Cash was created which has a block size limit of 8 MB. Note that these are two completely different blockchains and sending Bitcoin to a Bitcoin Cash wallet (or vice versa) will result in a failed transaction.
Update: As of May 15th, 2018 Bitcoin Cash underwent another hard fork and the block size has increased to 32 MB.
On the topic of Bitcoin vs Bitcoin Cash and which cryptocurrency is better, I’ll let you do your own research and make that decision for yourself. It is good to know that this is a debated topic within the community and example of the politics that manifest within the space. Now if you see community members arguing about this topic, you’ll at least have a bit of background to the issue.

What is Block Reward?

Block reward is the BTC you receive after discovering a block. Blocks are discovered through a process called mining. The only way new BTC can be added to the economy is through block rewards and the block reward is halved every 210,000 blocks (approximately every 4 years). Halving events are done to limit the supply of Bitcoin. At the inception of Bitcoin, the block reward was 50BTC. At the time of writing this, the block reward is 12.5BTC. Halving events will continue to occur until the amount of new Bitcoin introduced into the economy becomes less than 1 Satoshi. This is expected to happen around the year 2,140. All 21 million Bitcoins will have been mined. Once all Bitcoins have been mined, the block reward will only consist of transaction fees.

Technical Aspects Continued

Understanding Nodes

Straight from the Bitcoin.it wiki
Any computer that connects to the Bitcoin network is called a node. Nodes that fully verify all of the rules of Bitcoin are called full nodes.
In other words, full nodes are what verify the Bitcoin blockchain and they play a crucial role in maintaining the decentralized network. Full nodes store the entirety of the blockchain and validate transactions. Anyone can participate in the Bitcoin network and run a full node. Bitcoin.org has information on how to set up a full node. Running a full node also gives you wallet capabilities and the ability to query the blockchain.
For more information on Bitcoin nodes, see Andreas Antonopoulos’s Q&A on the role of nodes.

What is a Fork?

A fork is a divergence in a blockchain. Since Bitcoin is a peer-to-peer network, there’s an overall set of rules (protocol) in which participants within the network must abide by. These rules are put in place to form network consensus. Forks occur when implementations must be made to the blockchain or if there is disagreement amongst the network on how consensus should be achieved.

Soft Fork vs Hard Fork

The difference between soft and hard forks lies in compatibility. Soft forks are backwards compatible, hard forks are not. Think of soft forks as software upgrades to the blockchain, whereas hard forks are a software upgrade that warrant a completely new blockchain.
During a soft fork, miners and nodes upgrade their software to support new consensus rules. Nodes that do not upgrade will still accept the new blockchain.
Examples of Bitcoin soft forks include:
A hard fork can be thought of as the creation of a new blockchain that X percentage of the community decides to migrate too. During a hard fork, miners and nodes upgrade their software to support new consensus rules, Nodes that do not upgrade are invalid and cannot accept the new blockchain.
Examples of Bitcoin hard forks include:
  • Bitcoin Cash
  • Bitcoin Gold
Note that these are completely different blockchains and independent from the Bitcoin blockchain. If you try to send Bitcoin to one of these blockchains, the transaction will fail.

A Case For Bitcoin in a World of Centralization

Our current financial system is centralized, which means the ledger(s) that operate within this centralized system are subjugated to control, manipulation, fraud, and many other negative aspects that come with this system. There are also pros that come with a centralized system, such as the ability to swiftly make decisions. However, at some point, the cons outweigh the pros, and change is needed. What makes Bitcoin so special as opposed to our current financial system is that Bitcoin allows for the decentralized transfer of money. Not one person owns the Bitcoin network, everybody does. Not one person controls Bitcoin, everybody does. A decentralized system in theory removes much of the baggage that comes with a centralized system. Not to say the Bitcoin network doesn’t have its problems (wink wink it does), and there’s much debate amongst the community as to how to go about solving these issues. But even tiny steps are significant steps in the world of blockchain, and I believe Bitcoin will ultimately help to democratize our financial system, whether or not you believe it is here to stay for good.

Final Conclusions

Well that was a lot of words… Anyways I hope this guide was beneficial, especially to you crypto newbies out there. You may have come into this realm not expecting there to be an abundance of information to learn about. I know I didn’t. Bitcoin is only the tip of the iceberg, but now that you have a fundamental understanding of Bitcoin, learning about other cryptocurrencies such as Litecoin, and Ethereum will come more naturally.
Feel free to ask questions below! I’m sure either the community or myself would be happy to answer your questions.
Thanks for reading!

November Fork - The Facts

Update: Thank you for your appreciation on this article. I decided to publish it on Medium.  
You can find the article on this link.
 
Existing Article:
With less than a dozen days left before the SegWit2X fork, I thought I'd start gathering some facts before I start forming personal opinions and speculative conclusions. I refer to the SegWit1X chain as 1X and the SegWit2X chain as 2X for simplicity, and I have looked for very simple facts and safe assumptions. Here are the dots that I gathered:  
 
• Fork at Block 494,784. Approximate date = 16th of November.  
 
The New York Agreement: The NYA involved parties representing about 83% of the then hashing power who all agreed to both hardforks - one for SegWit and another for an increased block size of 2MB (2X) within 6 months of the former. Further details in reference 1.  
 
• It is safe to assume that miners will only mine the most profitable chain (possibly several chains in differing proportions).  
• If whales pump a single chain it will gain more value. If this happens, miners will be more inclined to mine that particular chain only. This will result in the other chain(s)potentially losing overall mining attractiveness.  
 
1X will continue to have a 1MB block and SegWit;  
2X will have a 2MB block and SegWit;  
Bitcoin Cash (Just for info right now) currently has an 8 MB block with NO SegWit;  
 
Current Price Status (Futures) on BitFinex: 2X/BTC = 0.17; 1X/BTC = 0.83  
 
Current Mining Status: 2X = Around 85% of blocks are signalling for 2X.  
It seems only a few mining pools including Slush Pool, F2Pool and Kano CKPool are not signalling Segwit2X. All Antpool (Jihan Wu) owned pools are signalling for Segwit2X and will likely continue to do so up to the fork. It is not clear if any other pools from the Segwit2X signalling group will change their minds in the meantime.  
 
Lower mining power chain: Likely to be 1X. Fees likely to be extremely high as not many miners. Difficulty adjustment could take a few weeks, if not months. Until then it will be very difficult to transfer funds. [It may be better to keep BTC on an exchange before fork, to ease liquidity cost/time if you want to sell either of the coins immediately]  
 
Double-spending: Miners (from 2X) will have an ability and incentive to double-spend on the minority chain (lower mining power chain). If you have huge mining power, you can allocate some of it to just double-spend on the minority chain. Some people will possibly lose confidence in the minority chain as a result.  
 
Replay-Protection: Neither 1X nor 2X currently have replay protection.

The opinion section
Vinny Lingham's opinion: 2X will outcompete 1X.  
 
Enter Bitcoin Cash: A review by Ryan X. Charles who has incorporated some of Vinny Lingham's quotes, states the following:  
 
a. BCH is a fork of BTC with same PoW, but with improved Difficulty Adjustment Algorithm (DAA). BCH cannot die, but 1X and 2X could both die. If whales shift most of their holdings to BCH (or another coin), that would incentivise the miners to mine BCH (or another coin) instead of 1X and 2X. Both 1X and 2X would lose their mining power; however Core would release an emergency update to software adding DAA like BCH (or another coin). Thus, 1X would survive, and 2X (which might not get DAA) would die.  
 
b. If 2X continues to be the dominantly mined chain, 1X will be forced to launch an emergency update to their PoW with DAA. There could be fighting between the two chains, and as a result a struggle to become dominant potentially causing altcoins to flourish.  
 
My observations
BCH is upgrading their EDA (Emergency Difficulty Adjuster) on Nov 13. See website. This will lead to reduced volatility in BCH - likely making it more attractive to more long-term miners.  
 
Mining profitability: It is currently almost equally profitable to mine either BTC or BCH.  
 
• What to keep and eye on before the fork to judge yourself where the fate of BTC is heading.  
  1. Mining signalling distribution
  2. DAA: 1X or 2X software updates to implement Difficulty Adjustment Algorithms
  3. Futures price before fork
  4. Significant whale movement

What they really don't wan't you to know about Dash!

Dash is breaking away with regards to integrations, partnerships and developments that advocates of other Crypto Currencies have become frightened of Dash's future dominance. Unfortunately for most of these other Crypto Currency projects Dash as a platform is well and truly in the driving seat on so many levels.
Lets take a look at some of the achievements in 2017 and upcoming events:

Congratulations r/Bitcoin! You have created a decentralised discussion! (P.S. Ghash.io is EVIL)

We get it. Ghash.io's hashrate is high. If your post can't fit into one of these threads about ghash.io, it's probably not adding anything substantial to the conversation.
EDIT: Decided that instead of whinging, I will try to help the community access the information that is most relevant to them. Before posting a new thread, check if one of these may be relevant.
EDIT 2: Now that Ghash.IO has made an official press release claiming that they will not act maliciously, I am going to get some well deserved shuteye. I am sure the saga will continue on without me.
Press Release from Ghash.IO
Bitcoin mining pool GHash.IO is preventing accumulation of 51% of all hashing power
Current Network Hashrate
Hashrate Distribution
Warning about Ghash.IO and Cex.IO
GHash.IO At 42% Of Mined Blocks Over Past 24 Hours.
LEAVE GHASH.IO if you mine there!
WARNING: GHASH.IO IS NEARING 51% – LEAVE THE POOL
Bitcoin Miners, Step Away From GHash.IO !
GHASH.IO RISKING WHOLE BITCOIN NETWORK KNOWN ATTEMPTED DOUBLE SPEND BY THEM
ghash.io is becoming SHOCKINGLY AGGRESSIVE NOW, closing in 45%
LEAVE GHASH.IO
WARNING: GHASH.IO IS NEARING 51% – LEAVE THE POOL (with image)
Miners Boycot Ghash.io as the Pool approaches 51% of network hashrate
If the situation with GHash.IO has shown us anything, it is that it's time we move to a p2pool.
FOR THE LOVE OF GOD CHANGE THE FUCKING POOL IF YOURE ON GHASH.IO
Stop buying cloud mining at cex.io
If a large portion of mining pools are 'unknown', does this mean GHASH.IO could potentially already be over 50%?
Bitcoin Miners Ditch Ghash.io Pool Over Fears of 51% Attack
CEX.io staff threatening customers now for talking about the approaching 51% mining share...
GHASH.IO IS THE ANTICHRIST!
"How do we fix this?/Why is this bad?"
Instead of having to boycott GHash.IO, maybe fix Bitcoin?
Discussion: Mining Pools and their future
We need a mining pool with a good looking website like GHASH.IO and its affiliates
Reason why miners like me won't leave GHASH.IO or won't stop purchasing cloud based mining power through CEX.IO
I think part of the problem is that some miners don't know how to switch pools. Could some of you veterans please direct folks to the necessary guides?
Can't just restrict max number of continuous blocks from a pool / miner to one (context; big mining pools nearing 51% hash rate)
Possible GHASH.IO solution (one for the devs)
Why not issue alerts for things that threaten Bitcoin's health such as GHASH?
Explanation of Double-Spending (51% Attack) regarding nearing 51% of GHash.IO
Question: what are downsides if Ghash.IO hit 51% but choose not to doublespend?
The whole Gash.io Debacle
Looking for alternative cex.io or ... ?
The network health of Bitcoin is awful. The 2 largest pools comprise 60% of the network. All you need to do to take over the network is coerce 2 people. Please switch to P2Pools.
We love Satoshi, Satoshi was a genius, but Satoshi's mining approach just isn't working out in practice and needs to be changed.
A screen saver like the old SETI one, that only mined with P2P pool possible?
Pool Voting: Encrypting Bitcoin Transactions To Be Processed By Specific Pools
Vitalik's thoughts on the Ghash.io issue
Problem with pooled mining in general
don't want bitcoin to get 51%? support this !!
Why is a pool owning +51% of the mining network not so bad?
Could a malicious entity with a lot of hashpower (say 10% of the total network) intentionally hurt other pools?
ELI5
ELI5: Why is so bad GHASH.IO has a 51%+ marketshare?
Can someone ELI5 this whole GHASH.io 51% thing?
ELI5: Double spending
Community Reaction
Bitcoin as of late
I can't quite tell if people here think ghash.io is a problem...
Seemingly some people are upset about GHash.IO's recent increase in hashrate share...
Incase you missed it...
Is this really necessary? It is almost as melodramatic as that suicide hotline post...
Reddit idiots panicking over nothing again. Cex.io has a great business model.
GUYS QUICK! POST THAT PEOPLE SHOULD STOP USING GHASH.IO!
People have figured it out, stop posting about leaving Ghash
Clearly GHASH.IO is simply an exceptional pool that is naturally rising to the top. Why do you captains of industry want to hold them back with regulations?
Stop with the GHash.IO nonsense!
Why is no-one talking about the problems with GHASH.IO?
LEAVE GHASH.IO NOW!
Just got 8 Avalons, is Ghash.io the best pool to join?
Memes
Insanity wolf would like to have a word with you all
51%!
My dad's thoughts after I explained Ghash
Speculation
BTC Gigahash 51%, of to PeerCoin/POS+POW :)
The price of bitcoin didn't fall even a bit and maintained its average day price even through the ghash.io scare. Reasons?
Investor here. Does the Ghash.io thing have anything to do with the Yahoo malware?
The lack of privacy/anonymity, & the lack of incorporation of the P2P mining in BTC, is for the first time making me feel as though a successor is, or should be, near.
Threats against ghash.io
Let's Just DDOS the bastards and end this all ready.
I am going full fiat and you should too. We need a crash in price: it's the only signal miners can't ignore.

BIP 101 = KISS ("Keep It Simple, Stupid")

It's better (ie: safer) to just...
... rather than inventing a whole new level-1 protocol such as Lightning Network.
BIP 100 is more complicated than BIP 101 in terms of game theory, economics, or predictability - which means that BIP 101 is better - ie safer - than BIP 100.
LN is a non-trivial engineering task, with no guarantee of success. LN might be a great idea and we should be happy that people are working on it - but it sure ain't KISS.
Evolving viewpoints
A few years ago, I was actually suspicious of Mike (because of proof-of-passport) and Gavin (because of that meeting with the CIA) - and I preferred the idealistic and speculative mathematical and game-theory scenarios discussed by guys like Adam Back and Peter Todd. It was just so much more “clever” and hence more appealing to the side of me that likes complicated puzzles and idealized solutions in the realms of mathematics and programming.
I have the greatest respect for Adam Back as a cryptographer, mathematician and innovator. For example, his proposals for "homomorphic encryption" which he shared on bitcointalk.org could provide the groundwork someday for much more anonymity in Bitcoin.
And I have read and liked a lot of stuff from Peter Todd - from back when he dumped a bunch of his coins when cex.io got close to triggering a 51% mining threat, and his more complicated stuff regarding RBF. I like math and programming and I like clever complicated solutions!
But, after reading everything I could find in the past few months on both sides of the block size debate, I've finally been getting some serious reminders about how starry-eyed and idealistic and impractical mathematicians and programmers can be. (I include myself in this group by the way – although I’m not great at math or programming, I have studied and worked a lot in these areas.)
Mike has a lot of practical experience dealing with security and scaling at Google (plus also implementing LevelDB in Bitcoin, and implementing a Java client BitcoinJ paving the way for clients on Android), and Gavin has a lot of practical experience from his time as the lead maintainer of the original Bitcoin client - and they both show the kind of maturity and practicality and common sense (and understanding of scaling and game theory and economics and threat modeling) which are most important for ensuring the success of an open-source project.
Some reference material
If you have time, I recommend perusing Mike's posts at the link below, where you see that not only has he done some important coding on Bitcoin (changing from Berkeley DB to LevelDB, writing BitcoinJ) but he also has a solid experience and understanding of how to prioritize issues involved in major programming projects:
https://www.reddit.com/useMike_Hearn
And I also recommend the recent video from Gavin, where he shows a clear understanding of governance and consensus on open-source projects:

Meanwhile, although I was enthralled for a while with some of the innovative mathematical ideas from Adam and exotic game-theory threats from Peter, I no longer think that these things should be prioritized - to use a word which occurs frequently in Mike Hearn's discussion of threat models on Google Groups:
https://groups.google.com/forum/#!searchin/bitcoin-xt/threat$20model/bitcoin-xt/zbPwfDf7UoQ/4uySXHVZCAAJ
I myself can get heavily into mathematics and programming (and can often spend way too much time pursuing things in those areas which are not a priority), so I appreciate the "managerial" common sense and maturity displayed by people like Mike and Gavin to establish priorities and deal with the most important things first.
I also think that Mike and Gavin have a much more realistic and practical understanding of "governance" and "consensus": namely, for a network running open-source code, there is no such thing as "developer consensus". Anyone (including an anonymous developer - anyone remember Satoshi Nakamoto?) can release anything they want - and then it is up to the network to decide to adopt it or not. This is the only real meaning of consensus.
And, as Mike has stated elsewhere: if the code cannot be forked, then it's not open-source.
The biggest priority in the short term (for the next few years at least) is to provide a simple scaling solution to support more user adoption, making maximal leverage of the stuff we already have: the existing code base and the available hardware and infrastructure. This is the direction that Gavin and Mike have been focusing on.
(By the way, as Mike has also pointed out elsewhere: user adoption itself is a very important metric of decentralization. If hundreds of millions more people start using the block chain directly in the next few years, this grassroots popularity really strengthens the system against many significant threats, such as interference from hostile state or corporate actors.)
Meanwhile, I think Adam's work on LN is something which could be important for the longer term - while some of the areas which Peter have focused on (such as RBF and "scorched earth") might be merely marginal improvements - or might actually make the system worse.
Shower thought: What if Adam had been more of an early adopter?
The other day I had a "shower thought" where I wondered what would happen if 1,000 people all donated 1 BTC each to Adam Back right now.
Evidently Adam, while being a fine mathematician / cryptographer and the inventor of the Bitcoin forerunner HashCash, was actually not a big-time early adopter of Bitcoin, so he apparently doesn't have very much "skin in the game" in terms of actual stake as a holder on the current level-0 block chain.
I sometimes wonder how things would be now if Adam had "gotten in on the ground floor" as an early "hodler". It might make him more inclined to work on providing improvements to level-0 (the block chain), instead of going off in some other direction trying to invent some complicated new level-1 system (Lightning Network).
KISS
Regarding the block size debate, we should apply the "KISS" principle here: "Keep It Simple, Stupid".
BIP 101 follows this KISS approach, while LN and BIP 100 (and side-chains and other interesting proposed projects such as RBF) are non-KISS, and hence more risky, and hence should be deprioritized (or perhaps even deprecated). This is simply practical common sense based on the experience of successful managers of big projects including scaling open-source software.
In a nutshell: if space on the block chain is starting to look like it might get congested in the near future, and more hardware and infrastructure are available right now and in the foreseeable future, then we have a choice between...
...then it's a no-brainer that the first option is the safer choice to scale the network in the short term.
Yes I've heard all the arguments that increasing the maximum block size could lead to more centralization - but this is something we can keep an eye on in advance.
https://getaddr.bitnodes.io/nodes/
Meanwhile, LN represents in some sense a kind of "hard fork" of an entirely different (ie much more complex) nature: Instead of simply changing just a single parameter while keeping 99% of the code and throwing more hardware at the problem, LN proposes making deep, major, "clever", non-KISS and unstudied changes in the architecture and topology (and game theory and economics) of the whole system itself.
And BIP 100 proposed a more-complicated voting procedure - giving miners too much say regarding the block size, and introducing more unpredictability (since the votes could lead to a wildly fluctuating max block size over the years).
Managers (and users and venture capitalists) love simple solutions where you can get 10x - 1000x - 10,000x scaling for the next few years (or decades) simply by throwing some more hardware and infrastructure at the problem, while leaving the existing codebase 99% unchanged. This is what BIP 101 does, and this is why people will adopt it instead of unproven, untried, untested, un-coded (vaporware) alternatives such as LN - or more complicated, unproven, untried, untested, riskier game-theory approaches such as BIP 100.
TL;DR: BIP 101 = KISS = Keep It Simple Stupid.
Just change a parameter and throw some more hardware at the problem and don't change anything else - ie, go with BIP 101.

November Fork - The Facts

With less than a dozen days left before the SegWit2X fork, I have started gathering facts before I start forming personal opinions and speculative conclusions. I refer to the SegWit1X chain as 1X and the SegWit2X chain as 2X for simplicity, and I have looked for very simple facts and safe assumptions. Here are the dots that I gathered:  
 
• Fork at Block 494,784. Approximate date = 16th of November.  
 
The New York Agreement: The NYA involved parties representing about 83% of the then hashing power who all agreed to both hardforks - one for SegWit and another for an increased block size of 2MB (2X) within 6 months of the former. Further details in reference 1.  
 
• It is safe to assume that miners will only mine the most profitable chain (possibly several chains in differing proportions).  
• If whales pump a single chain it will gain more value. If this happens, miners will be more inclined to mine that particular chain only. This will result in the other chain(s)potentially losing overall mining attractiveness.  
 
1X will continue to have a 1MB block and SegWit;  
2X will have a 2MB block and SegWit;  
Bitcoin Cash (Just for info right now) currently has an 8 MB block with NO SegWit;  
 
Current Price Status (Futures) on BitFinex: 2X/BTC = 0.17; 1X/BTC = 0.83  
 
Current Mining Status: 2X = Around 85% of blocks are signalling for 2X.  
It seems only a few mining pools including Slush Pool, F2Pool and Kano CKPool are not signalling Segwit2X. All Antpool (Jihan Wu) owned pools are signalling for Segwit2X and will likely continue to do so up to the fork. It is not clear if any other pools from the Segwit2X signalling group will change their minds in the meantime.  
 
Lower mining power chain: Likely to be 1X. Fees likely to be extremely high as not many miners. Difficulty adjustment could take a few weeks, if not months. Until then it will be very difficult to transfer funds. [It may be better to keep BTC on an exchange before fork, to ease liquidity cost/time if you want to sell either of the coins immediately]  
 
Double-spending: Miners (from 2X) will have an ability and incentive to double-spend on the minority chain (lower mining power chain). If you have huge mining power, you can allocate some of it to just double-spend on the minority chain. Some people will possibly lose confidence in the minority chain as a result.  
 
Replay-Protection: Neither 1X nor 2X currently have replay protection.  
 
Exchanges:
  1. Bitfinex: original chain is “BTC”, SegWit2x chain is “B2X”  
  2. BitMEX: Original chain is BTC  
  3. Bitstamp: Unknown  
  4. GDAX & Coinbase: hash power and market cap decides which chain is “BTC”  
  5. Kraken: Unknown

  9. Gemini: hash power decides which chain is “BTC”  
  10. Coinfloor: Unknown  
  11. BTCC (Updated on Twitter): BTCC will consider which of 1MB and 2MB to name as #bitcoin based on market feedback and adoption.  
Further details in reference 4.  
 
The opinion section
Vinny Lingham's opinion: 2X will outcompete 1X.  
 
Enter Bitcoin Cash: A review by Ryan X. Charles who has incorporated some of Vinny Lingham's quotes, states the following:  
 
a. BCH is a fork of BTC with same PoW, but with improved Difficulty Adjustment Algorithm (DAA). BCH cannot die, but 1X and 2X could both die. If whales shift most of their holdings to BCH (or another coin), that would incentivise the miners to mine BCH (or another coin) instead of 1X and 2X. Both 1X and 2X would lose their mining power; however Core would release an emergency update to software adding DAA like BCH (or another coin). Thus, 1X would survive, and 2X (which might not get DAA) would die.  
 
b. If 2X continues to be the dominantly mined chain, 1X will be forced to launch an emergency update to their PoW with DAA. There could be fighting between the two chains, and as a result a struggle to become dominant potentially causing altcoins to flourish.  
 
My observations
BCH is upgrading their EDA (Emergency Difficulty Adjuster) on Nov 13. See website. This will lead to reduced volatility in BCH - likely making it more attractive to more long-term miners.  
 
Mining profitability: It is currently almost equally profitable to mine either BTC or BCH.  
 
• What to keep and eye on before the fork to judge yourself where the fate of BTC is heading.  
  1. Mining signalling distribution
  2. DAA: 1X or 2X software updates to implement Difficulty Adjustment Algorithms
  3. Futures price before fork
  4. Significant whale movement

Beginner's Guide to Exchanges - Part 2

Beginner’s Guide to Exchanges – Part 2

A little late, but as promised here is Part 2 of the Beginner’s Guide to Exchanges. I would like to sincerely thank everyone for their support and feedback in making these.
Link to Part 1
This time I also made a Google Docs survey in the hopes of sharing the results with the community. I thought we could share what we use as a whole and why redditors choose the exchanges they do. For skeptics (as you all should be), I assure you that I am not collecting personal information. This is for recreation and if you are still wary, then by all means abstain!

06 – Fiat Exchanges – South Korea

안녕하세요 여러분! 혹시 우리 한국인 친구 이 보고서를 한국어로 읽고 싶어한다면 알려주세요. 관심이 많이 있다면 간단한 한국어 보고서도 만들 수 있습니다. This year, ETH has taken off like a rocket in the Land of the Morning Calm. With a population of just 50 million, South Koreans account for almost 30% of daily ETH trade volume. Even more surprising is that currently the daily volume of ETH is about 5 times higher than that of Bitcoin on Korean exchanges. Since demand is high, ETH is trading at a premium on Korean exchanges. Some users have been talking about capitalizing off this imbalance by trading on arbitrage between exchanges. For those who have no connection to Korea and hope to do so, I have bad news – all Korean exchanges require a National ID number and access to a Korean bank account. This makes Korean exchanges virtually closed to Korean nationals and those with long-term visas. Sorry everyone.

07 – Fiat Exchanges – China

With a great deal of anticipation, major Chinese exchanges started trading ETH this summer. Since these exchanges deal huge volumes of Bitcoin already, naturally it was expected that they invest heavily into ETH as well. So far this hasn’t quite lived up to the hype with many exchanges still favoring Bitcoin, Litecoin, Altcoins, and even Ethereum Classic (Gulp). Three of these exchanges underwent inspections by the Peoples Bank of China earlier this year and will be working closely with the government to ease fears of money laundering and market manipulation. There are a lot of Chinese sites, and since my Chinese is non-existent this list is basically just for name recognition. In many ways these sites are very similar in regards to security, verification, and fees compared to their western counterparts; just marketed at a different audience and currency. If users are seriously interested in these exchanges and making reviews, please contribute or ask!

Coin-a-Year: Nyancoin

Hello cryptocurrency lovers! Welcome to Coin-a-Year, the laziest series yet in the Coin-a-Day publishing empire. This year's coin is Nyancoin (NYAN). I originally covered Nyancoin in an article here in /cryptocurrency published January 4th, 2015.
Without (much) further ado, I'm going to include the original report next, unmodified. This is unlike my Coin-a-Week series, where I use strikeout and update in-text. Because this is going to be a longer update, I'll just make all further comments and updates below, just realize that all information below is as of January 4th, 2015 and thus is more than a year out of date as of posting now, at the end of February 2016.
Since I use horizontal rules as internal dividers in the original post, I'll use a double horizontal rule to divide the original text from this prelude and the following update.
Coin-a-Day Jan 4th
Welcome to the fourth installment of Coin-a-Day! To see convenient links to the introduction and the previous entries, please see /coinaday. Today's coin is Nyancoin (NYAN).
Summary
• ~173.6 million available currently [1]; 337 million limit [2]
• All-time high: ~0.000024 BTC on February 16, 2014 [1]
• Current price: ~3 satoshi [1]
• Current market cap: ~$1,275 [1]
• Block rate (average): 1 minute [1] [3]
• Transaction rate: ~25? / last 24 hours; estimated $3-4 [4]
• Transaction limit: 70 / second [5]
• Transaction cost: 0 for most transactions [6]
• Rich list: ??? [7]
• Exchanges: Cryptsy [8]
• Processing method: Mining [10]
• Distribution method: proof-of-work block rewards and 1% premine for "bounties, giveaways & dev support" [2] [10]
• Community: Comatose [9]
• Code/development: https://github.com/nyancoin-release/nyancoin ; there hasn't been a released code change in 10 months. The new developer has talked about some changes, but has not made a new release. He has given advice about how to keep the network running and operate the client. [10]
• Innovation or special feature: First officially licensed cryptocurrency (from Nyancat) [2]; "zombie"-coin [11]
Description / Community:
So you're probably wondering why in the world we're talking about a coin which has been declared dead and already written off. I actually first selected this coin to illustrate a "deadcoin", but the more I dug into it, the more I was amazed at the shambles I discovered. I am combining the description and community sections for this coin, because the community (or lack thereof) is the central issue for Nyancoin.
Substantially all, if not literally all, of the original infrastructure is gone. From the announcement post, the original website has expired. The nyan.cat site itself survives, but has no reference to the coin. The github repo remains, but then there was never much changed from the bitcoin/litecoin original. In fact, the COPYING file doesn't even list "Nyancoin Developers". None of the original nodes seem to be running anymore. @Nyan_Coin hasn't tweeted since July 6th. And that was just to announce posting an admittedly cute picture to facebook which makes a claim for a future which seems never to have developed. Of the original 15 pools, I think all are dead except p2pool, for which at least one node still supports NYAN. The original blockchain explorer, nyancha.in, is still running. The faucet is dead or broken. The original exchanges no longer list it (two of the three having died; SwissCEX having ended its trading as of the first of this year). And so forth.
And yet:

I'm not dead! I'm getting better!

No you're not, you'll be stone dead in a moment.
[Of course, that scene finishes with knocking out the "recovering" patient so he can be taken away...not to mention the absurdity of including Monty Python in a financial article, but moving right along.]
There is still just enough left to Nyancoin to keep it twitching, even if it is on life-support. Whether it's an individual node or whether it's a pool, there are blocks being produced at a steady rate as intended. Transactions are being processed. There is still a market. There is still a block explorer. And there is a dev. It is like a case study in the absolute minimum necessary to keep a coin alive. The most likely outcome is almost certainly a final collapse when one critical piece or another of the infrastructure goes away. And yet in the meantime, a person can own a million NYAN for $8 [12], and then move this coin quickly and easy, albeit with no particular external demand. It's like the world's most hyped testnet.
I think this case presents an interesting example of what happens to an altcoin when its initial support dries up. NYAN coin is more fortunate than some, actually, as there are some where there are no longer any nodes running it nor the original announcement thread (in fact, there was actually a second Nyancoin launched around the same time. But it died hard and its original announcement thread was deleted and at this point I would have no idea how to access it; so "Nyancoin" thus illustrates how hard a coin can die (Nyancoin 2) as well as how it can hang around despite being proclaimed dead, with far more justification behind that pronouncement than there has been for bitcoin (NYAN) ).
Footnotes
[1] http://coinmarketcap.com/currencies/nyancoin/
[2] https://bitcointalk.org/index.php?topic=402085.0 Regarding the premine, it's unclear to me where this money is now, since the original poster hasn't been active on BCT since May and the original site is down. However, given that it's only 1%, and about $25 in value right now, there seem to be more significant concerns for NYAN.
[3] http://nyancha.in/chain/Nyancoin - Nyan blockchain explorer; blocks are somewhat inconsistent but somewhere around the 1 minute average
[4] There doesn't seem to be anything automatically doing these stats, so I did visual inspection on about 1500 blocks (about one day) excluding the block generation reward (~250k/day). Most blocks are otherwise empty. I counted about 24 transactions or so scrolling through, with an outlier around 300k NYAN and another around 100k NYAN. In total, about 500k NYAN, excluding the block rewards. This is very approximately $3-4.
[5] Nyancoin is a basically unmodified, slightly out-of-date bitcoin as far as code goes, and ignoring the change in block rate and total coin supply, as well as the difficulty retarget after every block. So for purposes of estimating maximum possible transaction throughput, I start with bitcoin's estimated 7 transactions per second, and multiply by 10 for having a block on average every minute rather than every 10 minutes. In any event, this limit is not likely to be reached in the foreseeable future.
[6] Like bitcoin, transaction fees appear to be optional in Nyancoin. Unlike bitcoin, there is almost no transaction volume, and coins tend to sit for a relatively long time before being moved. So zero-fee transactions appear to be the norm from looking at a couple transactions on the block explorer.
[7] I couldn't find one. See the disclosure section of this article: your humble correspondent is likely represented in some way on a top 100 if one were to be made or if one exists, despite not holding it directly, depending on how the exchange holds it.
[8] I could not find any other exchanges still listing Nyancoin. SwissCex appears to have disabled it as of a couple days ago. Cryptsy has a notice that the NYAN/BTC market will be closing, but its NYAN/LTC market appears strong.
[9] Essentially all of the original sites, pools, faucets, etc. are dead and there has been very little to replace it. There is basically a single node, or perhaps a very few, which are running the blockchain. However, there is a developer still trying to hold things together, maxvall_dev, maxvall on BCT. He is the last hope for the NYAN.
[10] https://bitcointalk.org/index.php?topic=597877.0 This is the thread where maxvall took over as dev, and it also discusses switching to PoS, which hasn't happened as far as I know.
[11] "zombie"-coin: Not to be confused with ZMB (my god, does it ever end?). This is my term to describe a coin which is "undead": by rights it should be dead. And yet it's still walking around and acting like it's alive. What is it? What's going on? It's quite debatable whether this gives it any special value, but I find it an interesting state, and it's why this was chosen for early coverage. There are plenty of actually popular and successful coins, and we will go onto covering more normal selections; we're looking for variety rather than repetition. But I think this is an interesting example for what can go wrong, and yet in the midst of that, how little it takes for a coin to survive. In fact, it's almost like an alternate history bitcoin to me; this shows the concept that "it was run on one computer before; it can be run on one computer again" to some extent. And there are even some strange pragmatic benefits as well, like having no competition for getting a transaction into a block and thus zero transaction fees.
[12] And, in fact, the author chose to do so today, spending about 0.03 BTC for about 1 million NYAN.

Giveaway
Instead of a challenge today, since NYAN has enough challenges, I decided I would give away 10,000 NYAN to at least the first ten people who ask for it. This still remains at my discretion, but honestly, if you really want, say, 50,000 NYAN and create four new accounts to do so, I'll probably be too amused to say no. I don't expect to get ten requests. If I get more, I'll probably still fulfill them, but as with everything else, this is left to my whim.
Donations and Disclosure
Okay, this is an important one today because of the tiny market here. I actually hold less USD value in NYAN than in BTC, DOGE, and PPC (although my value in PPC might be about equivalent actually), but I hold more of the total market in NYAN than any of those three. And I'll probably be buying more. So I have a conflict of interest in writing this article.
I am not providing financial advice and I do not make any recommendations of any sort on any matters. Make your own decisions; do your own research. Please, I do not want to hear about anyone doing anything "on my advice." I am not offering advice.
I personally hold just over 1 million NYAN on Cryptsy right now.
Perhaps it would be better if I didn't write any articles about anything I were invested inspeculating on, but I started this series for my own education to further my speculation, so unfortunately, dear reader, your needs come second to my own. tanstaafl; you get what you pay for, and I'm giving you my thoughts.

Updates:
Summary
  • ~263.7 million NYAN currently exist [a]
  • Current price: ~7 satoshi [b]
  • Current market cap: ~$8,000 [c]
  • Transaction rate: ~185 / last 24 hours; ~3,300,000 NYAN (~$100) [d]
  • Exchanges: Cryptopia [e]
  • Community: We're not quite dead yet; in fact, I think we're getting better! [f]
  • Code/Development: I have an early draft of NYAN2, but I'm about six months past my initial goal for having it available to use. Life/work/lack of build machine/procrastination. NYAN2 will be a rebase onto a modern LTC codebase which will soft fork to fix a current vulnerability to a fork bug. For now, the network still runs on the same code that it did when I wrote the first article.
Discussion
I'm going to consider the community first, since I pointed it out as the weakness and central topic in the last one, then talk about the technical situation briefly, and then review the financial results.
The community has been excellent, if I do say so myself. We've got working infrastructure going thanks to the contributions of many Nekonauts (see [f]). Some original Nekonauts have returned or at least popped in from time to time, and new ones like myself have found Nyancoin (I would say given what I wrote in the original, I was still a skeptic of it at that point. Not that skeptics can't be Nekonauts, but I think I'd put my conversion to the cult of nyan shortly after writing that, even though I was already a nillionaire then for the heck of it.)
While I do look forward to seeing the community continue to grow in future years and consider that important, I don't think the community is our weakest point any longer; I think it's now our strongest point. I've tried to encourage the community's revival as best I could, including giving away tens of nillions in total, and lots of long rambling articles on my views on ethics and philosophy and frankly it's worked better than I would've really expected (or at least it has coincided with an effective recovery of the community). The community also helped me through at least a couple hard times personally in there as well.
The technical situation in Nyancoin is mostly unchanged but slightly improved, although with two additional known vulnerabilities. It's unchanged in that it's the same client. It's improved in that we have an active nyanchain explorer host (nyan.space), and we have a public draft of a plan for a soft forking security fix update in the near future (hopefully by the end of March (although I've slipped these deadlines before and may well miss March for release by a bit, I do think I'm inching closer now and then)).
The most serious vulnerability is to forking. This is the bug which hit Peercoin if I recall correctly. NYAN2 is intended to solve this through its soft fork from the LTC fix upstream (from the BTC fix upstream). In the meantime, we've been lucky we haven't been attacked. The tiny marketcap probably helps with not being a particularly attractive attack target. We're not exactly about to pay ransom to move faucet outputs. But that's no excuse; we want this fixed and should have it finally done "soon" (tm).
The less serious vulnerability is to a time warp attack in the difficulty function (Kimoto Gravity Well), which relates to general weaknesses it has and issues we've had with large gaps in the block chain because of spikes in the difficulty function causing it to be unprofitable and driving away most of the hash, and then low difficulty and price rise making it attractive to more hash, creating a spike and causing it again. While this is irritating, the chain still works, even if there are fits and starts at times. An important part of the reason I can get away with this is because there is at least one Nekonaut-supporting miner, CartmanSPC, who rescues us from time to time, and did so during the course of this article being written. We have a bunch of pools, but sometimes the hash just isn't there to get us unstuck when the difficulty goes high enough. Another part of the reason I consider it not an especially serious issue is because there's a workaround which works for me (classic bad developer logic): I use a large transaction fee (generally 337 NYAN, although I might have halved it after the most recent halving, I'll probably use 337 again) on my personal wallet by default. If necessary, I use a couple of them. It can make NYAN profitable to mine again despite the higher difficulty and "unstick" the chain. The difficulty function can go back down again in the next block if the gap has been long enough, so that can be enough to keep it going again for a while (although it can also get stuck again irritatingly fast at times). A fix for this will be putting in a better difficulty function for NYAN3, which will require a hard fork. This is tentatively scheduled for feature freeze around the middle of this year, coding to follow, activation sometime early 2017.
Financial has been our most disappointing performance. A graph of the 1 year performance right now on coinmarketcap looks pretty sad, showing our fall from a little over 60 satoshi down to around 7 satoshi now.
We rose too high, too fast, and I didn't stick with the safe high paying job like a sane person. Instead I hit the road, went to jail, and worked minimum wage. That doesn't sound like a sentence from a cryptocurrency financial review, does it? But the performance of NYAN since the article has been the story of my personal finances, which is the story of my life since then.
So, autobiographical coinaday interlude, trying to keep it generally to the most salient points. Well, in 2014 I had been on my way home to Minnesota from California when I was pulled over leaving Eureka, Nevada for speeding (got sloppy and went 45 approaching the 45 sign and thus technically still in the 35; bored cop seeing out-of-state plates). My vehicle reeked of weed, what with having been in Mendocino County previously with no intention of traveling out of the county much less state anytime soon but family emergency brought me back, and the end result was a citation for possession of cannabis and paraphernalia along with the speeding.
Fast forward to the beginning of 2015, I'm settled into a good software position and start looking more at cryptocurrency in my spare time. I write the coin-a-day series for a bit and then got annoyed and quit after a while when trying to do one a day on top of an actual job was too much for me (along with some annoyance over criticism; I can be rather thin-skinned at times). But I had gotten interested in Nyancoin, and started buying it up more and more with extra money I was making.
And then comes the crash. I had to stop putting as much in as I realized that where I was living and what I was working on wasn't going to work out for me and I needed to figure something else out. So, as I seem wont to do, I went on a roadtrip. I quit my job. And I went back for the court date for my citations and refused to pay, instead spending 10 days in jail rather than pay ~$1400 (I actually had the money in cash available to me if I chose to pay as a backup if I chickened out, but the judge annoyed me enough that I really preferred to be jailed instead of paying, as stupid as that sounds since I'm quite sure the judge didn't care in the least one way or another).
After that, I went back to roadtrip lifestyle for a while. It was a nice period. A lot of beautiful scenery; a lot of reading. Eventually, I busted up my car pretty badly...a couple times actually, the second time for good. Fast forwarding through the rest of the year, I worked a couple minimum wage jobs to pay bills and avoid cubicle life and kill some time until I figured out what I was going to do next. Just recently I quit as delivery boy after getting a speeding ticket (I swear, I'm not as horrible of a driver as this makes me sounds, although I have had a bad tendency to speed in the past, which I really have curbed to almost nothing; but I'm clearly not good enough) and am currently writing a Coin-a-Year article with a friend's incentive and applying to do documentation and development with the Nu project.
Okay, so what did any of that have to do with NYAN? Well, it's the mess of a life that has led to the fall of the price from 60 satoshi to 7 satoshi. If instead my life history for the time since the article had been simply "I was happily employed writing software", then I don't believe we would have dropped below 20 satoshi. It's easy to see in hindsight. If anyone can lend me a time machine, I'm sure I can get some condensed instructions which should improve performance significantly. Otherwise, just going to have more chalked up for the "character building" tally.
So, lessons learned if you are the major buy support for your coin: you need long-term reserves. Whatever you put in bids can be taken out in a moment by a dump for no apparent reason. This is particularly true if you may be quitting your cushy, high-paying job and wandering around without income for an extended period of time. Rather obvious, but hey, maybe someone else can learn from my mistakes. If I'd been bidding as cautiously as I am now from the beginning, I think the price would probably be somewhere from 10-20 satoshi now instead of around 7 satoshi.
It's especially unfortunate given that I wanted to be able to demonstrate the more consistent growth possible building a stable store of value, as opposed to the pump and dumps common in altcoins. And instead we had a pump-and-dump looking graph ourselves after I bid up higher than I was able to sustain, and a large (10+ nillion) instadump crashed the market all the way back down to 1 satoshi momentarily. We've had a few large (2+ nillion) dumps since, but nothing that large. We haven't generally had that large of bids though either.
It's hard to know when I've exhausted the supply at a price level, when it sometimes waits for a couple weeks or even more and then fills all the bids at once. But I want to maximize the minimum price paid because I think that's important for building confidence in a store of value long-term, which is one of my core goals for NYAN.
At the same time, we're still up from the lowest parts of the floor and where I found it. Since I own about 30% [g], the very cheapest supply has been taken off the market. I plan to keep on buying up "cheap NYAN" as much as I can. I've bought up to 60 satoshi before, I'll probably buy up that high this time around. I've got a token 100,000 NYAN ask at 300 satoshi; I hope never to sell lower.
Conclusions
Now I try to wrap it all together as if I saw this all coming and am the wise expert, despite having had about 90% drop in price in the last year after bidding too high. My original concept was taking the "minimum viable coin" and reviving it to a powerhouse as a textbook example in how to do it.
Part of my core concept in this is the arbitrariness of value: throughout history, humans have chosen any number of things as a store of value for the time: salt, large rocks, certain metals, disks, marked sticks, and so forth. While there has generally been a certain logic in the choice, in that there is a locally restricted supply in one way or another, and so forth, from the perspective of other centuries or cultures the choices can seem quite strange. Growing up, I was always struck by how strange the notion of salt being limited and valuable seemed in a world where people were trying to reduce intake and large amounts could be bought for trivial sums. And yet, a key nutrient necessary for life fundamentally makes more sense as being valuable than notched sticks or printed paper or a piece of plastic with some encoded information.
Humans have perpetually come up with stranger and stranger ways of storing and transferring value. Each new step, as always, comes with its own disadvantages and, frankly, has generally appeared nonsensical at best and fraudulent at worst to the status quo. Which doesn't mean that each new attempt is valuable. The gold bugs always like to point out that every fiat currency ultimately returns to its true value of zero. And the skeptics of cryptocurrency argue that all cryptocurrencies will eventually return to their true value of zero.
It's certainly possible. And it's possible the USD will hyperinflate someday. I tend to try the moderate view for a plausible guess of the future. By that type of logic, I would guess that over the course of decades, USD will in general lose value, and cryptocurrency will tend to slowly gain value. That might not seem the moderate view, but USD not losing value over decades would be truly shocking. And hyperinflation has been predicted since the USD went off the gold standard, or before. So some amount of inflation less than hyperinflation seems like the safe guess (but then, the Titanic arriving would also have seemed like the safe guess to me). And with cryptocurrency, I think it's clear by now the technology will continue to survive. So my first question is with what overall value as a market? It could go down, of course, but that seems unlikely in an already small, young market. Even if all the current crop die off and are replaced, whatever cryptocurrencies are around should be able to do better than a handful of billion in market cap in my view.
I believe that cryptocurrency has a bright future ahead of it. The best coins should ultimately survive and thrive. But I've been wrong on most of my major calls so far, like for instance when I thought BTC was over-priced around $5-$10.
I think Nyancoin can have an important role to play in the future of cryptocurrency in the years and decades to come, but it's a massively speculative long-shot. See also Nyancoin risks document. But like Linus Torvalds' autobiography, I try to keep "Just for Fun" as a core motto and principle. It's makes for a good hobby project because there will always be more to work on, with a core community motto of
TO INFINITY AND BEYOND!

As I said before:
I am not providing financial advice and I do not make any recommendations of any sort on any matters. Make your own decisions; do your own research. Please, I do not want to hear about anyone doing anything "on my advice." I am not offering advice.
And I'll reiterate that I own about 30% [g] of the current supply of NYAN, which makes me by definition maximally biased.
Also, I'm not sure what's up with the address from the first post. It doesn't show up in my current wallet as a recognized address. So, anyhow, don't send there. :-) If you'd like to donate, please consider sponsoring a coin-a-day or coin-a-week article.
This is the first sponsored article. This Coin-a-Year article has been brought to you by spydud22 's generous patronage. I'd been meaning to do a Coin-a-Week article on Nyancoin for a while, but between wanting to "wait until the price recovered a bit" and general procrastination, then it seemed like it would make a good Coin-a-Year article, and then I wanted to wait until the price recovered a bit more...anyhow, so thank you spydud22, for causing me to finally do this. :-)
Footnotes
  • [a] nyan.space/chain/Nyancoin ; as of block 1091430, 263738786.71890615 NYAN outstanding. This is slightly over 50% more than the last report, which is what we would expect, since it had existed for about a year then, and has approximately annual halvings. The first year generated about 50% of total supply; the second year generated about 25% of total supply. We should expect in a year to have about 17% (one-sixth) more than we have now.
  • [b] https://www.cryptopia.co.nz/Exchange?market=NYAN_BTC ; this is the only market reflected in coinmarketcap and it is the primary one on which I trade. Cryptopia also has other base pairs which operate at significantly higher spreads (lower bids; higher asks) and have minimal volume. In the time since the last report, NYAN has traded as high as 60 satoshi (and briefly a little higher at times), but over the last almost twelve months since a peak about a year ago, the price has been generally declining overall, as a gross oversimplification of a lot of movements. This has been an effect of me not being able to keep buying as much and there being large dumps I wasn't expecting from time-to-time. Now I'm taking the approach of building large (one or more nillion (million NYAN)) bids on each price as I slowly work my way back up again in order to be able to handle possible dumps with less price shock.
  • [c] coinmarketcap.com/currencies/nyancoin/ ; as noted in [b], this only reflects the /BTC basepair on Cryptopia but that's where most of the volume is anyhow. Of course, the market is also not particularly liquid since I'm the primary buyer and have rather limited means currently.
  • [d] I haven't setup a script to count this yet, among many things on my to-do list for someday, so I went through by hand from what was the then-latest block of 1091430 on nyan.space back to 1089766 which was the first block generated less than 24 hours before. There was actually a three and a half hour block gap at that point, such that the next prior block was about 24 hours and 15 minutes before 1091430 while 1089766 was only about 20 hours and 45 minutes prior, and has a disproportionate number of transactions and value compared to a typical block (8 and ~313,000 NYAN respectively) from the build-up during the gap. But since that gap conveniently started right about at the start of the 24 hour period, doesn't really skew our results here.
Note that there are often times where the UTXO created during one transaction during the day is spent during a later transaction in the day. This can be considered the "same" Nyancoin being "spent" twice in the same day in our total. But in practice, I believe what's happening here is the faucet is breaking off small (10-50 NYAN) pieces from a larger (~40,000 NYAN) chunk, and so that pops up a bunch of times. So the total NYAN blockchain volume as counted for this topline number should not be interpreted as "NYAN spent in the day" but "NYAN moved on the chain", where the "same coin" can move many times. So it's a very easily gamed metric and not a strong / resistant metric like the market price tends to be (at least relatively speaking), but it's a fun number to calculate and provides a little bit of information.
The transaction count can also be easily inflated and certainly, for instance, having the faucet does generate transactions which are a very common transaction.
And this is also just an arbitrary 24 hour period compared to a previous arbitrary 24 hour period. Nonetheless, I do think there's clearly a bit more activity on the Nyanchain, even though the typical block is still empty and the number of transactions and volume is still tiny compared to the major cryptocurrencies.
Here's an arbitrary example of the faucet transactions Note the zero transaction fee, which I love that the miners support (the defaults are all quite low as well).
Here's an example of what may be the smallest transaction by NYAN volume of the day; but no, I followed its small, spent output, and it led to this gem which also links to this. I have no idea what's going on here, but it's hilarious and I love it. How's that for microtransaction support? :-)
  • [e] Obviously Cryptsy went down. We had had more than enough red flags with Cryptsy (including one time where I was able to withdraw 6 nillion more than I had in my balance) and got onto Cryptopia. spydud22 basically accomplished that for us, although I helped out in the tail end of the campaigning.
  • [f] Our community is still small (I wish there were literally dozens of us!) but we've had valuable activity from multiple people, including, just as highlights, vmp32k who hosts nyan.space, a clone of the original nyancha.in, jwflame who created the excellent nyancoin.info intro site, with the awesome status page (which currently notes that "the last 500 blocks actually took 111 minutes, which is approaching the speed of light, causing the universe to become unstable"), KojoSlayer who runs the faucet and dice, spydud22 who got us on Cryptopia, and many other Nekonauts have made worthy contributions, and the Nekonauts mentioned have done more than just that listed. So while we are small, we are active at least from time to time and technically capable.
Even though our posting rate is still around 1 post a day or so on average, and so still a relatively quiet subreddit (and it is our main (only?) hub), it's still a very noticeable and significant difference from how /nyancoins looked when I was reviewing it for the original piece here. Here's an attempt to approximate what was there using Reddit search ; archive.org has a snapshot on January 19th, 2015, which is well into the early revival mania and one from August 14th, 2014, before four and a half months of little to no activity. Apparently archive.org unsubscribed to /nyancoins in that interval itself...
  • [g] Maybe up to around 35% by now; maybe still around 30%. I haven't updated hodling report lately; it was 30% last time I recall, but I've bought more and more has been made since.
