Ultimate glossary of crypto currency terms, acronyms and abbreviations

I thought it would be really cool to have an ultimate guide for those new to crypto currencies and the terms used. I made this mostly for beginner’s and veterans alike. I’m not sure how much use you will get out of this. Stuff gets lost on Reddit quite easily so I hope this finds its way to you. Included in this list, I have included most of the terms used in crypto-communities. I have compiled this list from a multitude of sources. The list is in alphabetical order and may include some words/terms not exclusive to the crypto world but may be helpful regardless.
2FA
Two factor authentication. I highly advise that you use it.
51% Attack:
A situation where a single malicious individual or group gains control of more than half of a cryptocurrency network’s computing power. Theoretically, it could allow perpetrators to manipulate the system and spend the same coin multiple times, stop other users from completing blocks and make conflicting transactions to a chain that could harm the network.
Address (or Addy):
A unique string of numbers and letters (both upper and lower case) used to send, receive or store cryptocurrency on the network. It is also the public key in a pair of keys needed to sign a digital transaction. Addresses can be shared publicly as a text or in the form of a scannable QR code. They differ between cryptocurrencies. You can’t send Bitcoin to an Ethereum address, for example.
Altcoin (alternative coin): Any digital currency other than Bitcoin. These other currencies are alternatives to Bitcoin regarding features and functionalities (e.g. faster confirmation time, lower price, improved mining algorithm, higher total coin supply). There are hundreds of altcoins, including Ether, Ripple, Litecoin and many many others.
AIRDROP:
An event where the investors/participants are able to receive free tokens or coins into their digital wallet.
AML: Defines Anti-Money Laundering laws**.**
ARBITRAGE:
Getting risk-free profits by trading (simultaneous buying and selling of the cryptocurrency) on two different exchanges which have different prices for the same asset.
Ashdraked:
Being Ashdraked is essentially a more detailed version of being Zhoutonged. It is when you lose all of your invested capital, but you do so specifically by shorting Bitcoin. The expression “Ashdraked” comes from a story of a Romanian cryptocurrency investor who insisted upon shorting BTC, as he had done so successfully in the past. When the price of BTC rose from USD 300 to USD 500, the Romanian investor lost all of his money.
ATH (All Time High):
The highest price ever achieved by a cryptocurrency in its entire history. Alternatively, ATL is all time low
Bearish:
A tendency of prices to fall; a pessimistic expectation that the value of a coin is going to drop.
Bear trap:
A manipulation of a stock or commodity by investors.
Bitcoin:
The very first, and the highest ever valued, mass-market open source and decentralized cryptocurrency and digital payment system that runs on a worldwide peer to peer network. It operates independently of any centralized authorities
Bitconnect:
One of the biggest scams in the crypto world. it was made popular in the meme world by screaming idiot Carlos Matos, who infamously proclaimed," hey hey heeeey” and “what's a what's a what's up wasssssssssuuuuuuuuuuuuup, BitConneeeeeeeeeeeeeeeeeeeeeeeect!”. He is now in the mentally ill meme hall of fame.
Block:
A package of permanently recorded data about transactions occurring every time period (typically about 10 minutes) on the blockchain network. Once a record has been completed and verified, it goes into a blockchain and gives way to the next block. Each block also contains a complex mathematical puzzle with a unique answer, without which new blocks can’t be added to the chain.
Blockchain:
An unchangeable digital record of all transactions ever made in a particular cryptocurrency and shared across thousands of computers worldwide. It has no central authority governing it. Records, or blocks, are chained to each other using a cryptographic signature. They are stored publicly and chronologically, from the genesis block to the latest block, hence the term blockchain. Anyone can have access to the database and yet it remains incredibly difficult to hack.
Bullish:
A tendency of prices to rise; an optimistic expectation that a specific cryptocurrency will do well and its value is going to increase.
BTFD:
Buy the fucking dip. This advise was bestowed upon us by the gods themselves. It is the iron code to crypto enthusiasts.

Dapp (decentralized application):
An open-source application that runs and stores its data on a blockchain network (instead of a central server) to prevent a single failure point. This software is not controlled by the single body – information comes from people providing other people with data or computing power.
Decentralized:
A system with no fundamental control authority that governs the network. Instead, it is jointly managed by all users to the system.
Desktop wallet:
A wallet that stores the private keys on your computer, which allow the spending and management of your bitcoins.
DILDO:

Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

Where can I spend bitcoins?

Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.

Bull Bitcoin’s Dollar-Cost Averaging tool for Canadians: a detailed overview

Hello fellow Canadian Bitcoiners!
I'm Francis Pouliot, CEO and founder of Bull Bitcoin (previously known as Bitcoin Outlet) and Bylls.
I haven't been active on Reddit for a while but I thought I'd pop back here to let the community know about our new dollar-cost averaging feature, "Recurring Buy"
This post is a copy of my most recent medium article which you can read here if you want to see the screenshots. https://medium.com/bull-bitcoin/bull-bitcoins-dollar-cost-averaging-tool-for-canadians-the-right-time-to-buy-bitcoin-is-every-day-82a992ca22c1
Thanks in advance for any feedback and suggestions!
[Post starts here]
The Bull Bitcoin team is constantly trying to reduce the frictions ordinary people face when investing in Bitcoin and propose innovative features which ensure our users follow Bitcoin best practices and minimize their risks.
We are particularly excited and proud about our latest feature: an automated Bitcoin dollar-cost averaging tool which we dubbed “Recurring Buy”.
The Recurring Buy feature lets Bull Bitcoin users create an automated schedule that will buy Bitcoin every day using the funds in their account balance and send the Bitcoin directly to their Bitcoin wallet straight away.
We put a lot of thought in the implementation details and striking the right trade-offs for a simple and elegant solution. Our hope is that it will become a standard other Bitcoin exchanges will emulate for the benefit of their users. This standard will certainly evolve over time as we accumulate feedback and operational experience.
In this article, I cover:
The problem that we are trying to solve
Recurring Buy feature details, processes and instructions
The rationale (and tradeoffs) behind the main feature design choices
Bull Bitcoin is only available to Canadians, but non-Canadians that wish to have a look at how it works are welcome to make a Bull Bitcoin account and check out how it works here. You will be able to go through the process of create the schedule for testing purposes, but you wont be able to fund your account and actually purchase Bitcoin.
What problems does Dollar-Cost Averaging solve?
The most common concern of Bitcoin investors is, not surprisingly, “when is the right time to buy Bitcoin?”. Bitcoin is indeed a very volatile asset. A quick glance at a Bitcoin price chart shows there are without a doubt “worse times” and “better times” to invest in Bitcoin. But is that the same as the “right” time?
Gurus, analysts and journalists continuously offer their theories explaining what affects the Bitcoin price, supported by fancy trading charts and geopolitical analysis, further reinforcing the false notion that it is possible to predict the price of Bitcoin.
Newbies are constantly bombarded with mainstream media headlines of spectacular gains and devastating losses. For some, this grows into an irresistible temptation to get rich quick. Others become crippled with the fear of becoming “the sucker” on which early adopters dump their bags.
Veterans are haunted by past Bitcoin purchases which were quickly followed by a crash in the price. “I should have waited to buy the dip…”
Many Bitcoin veterans and long-term investors often shrug off the question of when is the right time to buy with the philosophy: “just hodl”. But even those holding until their death will recognize that buying more Bitcoin for the same price is a better outcome.
Given the very high daily volatility of Bitcoin, a hodler can find himself in many years having significantly less wealth just because he once bought Bitcoin on a Monday instead of a Wednesday. His options are either to leave it up to chance or make an attempt to “time the market” and “buy the dip”, which can turn into a stressful trading obsession, irrational decisions (which have a negative impact on budget, income and expenses) and severe psychological trauma. In addition, trying to “buy the dip” is often synonymous to keeping large amounts of fiat on an exchange to be ready for “when the time comes”.
There must be a better way.
Bitcoin investors should be rewarded for having understood Bitcoin’s long-term value proposition early on, for having taken the risk to invest accordingly and for having followed best practices. Not for being lucky.
Overview of features and rules
In this section I go into every detail of the Recurring Buy feature. In the following section, I focus on explaining why we chose this particular user experience.
The user first decides his target investment amount. Ideally, this is a monthly budget or yearly budget he allocates to investing in Bitcoin based on his projected income and expenses.
The user then chooses either the duration of the Recurring Buy schedule or the daily purchase amount. The longer the better.
The frequency is each day and cannot be modified.
The user must submit a Bitcoin address before activating a Recurring Buy schedule. By default, every transaction will be sent to that Bitcoin address. It’s the fallback address in case they don’t provide multiple addresses later.
Once the user has filled the form with target amount, the duration and the Bitcoin address, he can activate the Recurring Buy Schedule.
The user is not required to already have funds in his account balance to activate the schedule.
We will randomly select a time of day at which his transaction will be processed (every hour, so 24 possible times). If the user insists on another time of day, he can cancel his Recurring Buy schedule and try again.


The Recurring Buy feature as displayed on bullbitcoin.com/recurring-buys
The schedule is then displayed to the user, showing the time and date at which transactions that will take place in the future. The user will be able to see how long his current balance will last.
He can follow the progress of the dollar-cost averaging schedule, monitor in real time his average acquisition cost, and audit each transaction individually.
At this point, the user can and should change the Bitcoin address of his next transactions to avoid address re-use. Address re-use is not forbidden, but it is highly discouraged.
After having modified the Bitcoin addresses, there is nothing left for the user to do except watch the bitcoins appear in his Bitcoin wallet every day!
The Bitcoins are sent right away at the time of purchase.
Bitcoin transactions using the Recurring Buy feature will have the lowest possible Bitcoin network transaction fee to avoid creating upwards pressure on the fee market impact other network users.


What users see after first activating a schedule
The Recurring Buy schedule will be cancelled automatically at the time of the next purchase if the balance is insufficient. He can add more funds to his balance whenever he wants.
The Recurring Buy schedule will continue until the target amount is reached or until the account balance runs out.
The user can cancel his Recurring Buy schedule whenever he wants.
If the user wants to change the amount or duration of the schedule, he can simply cancel his current schedule and create a new one.
Each schedule has a unique identifier so that users can keep track of various schedules they perform over time.
Once a schedule is completed, either fully or partially, a summary will be provided which shows the number of transactions completed, the average acquisition cost, the total amount of Bitcoin purchase and the total amount of fiat spent. Useful for accounting!


A partially completed Recurring Buy schedule cancelled after 9 days due to insufficient funds
Though process in making our design choices
Recurring Bitcoin Purchases vs. Recurring Payment/Funding
The first and most important design choice was to separate the processes of funding the account balance with fiat (the payment) from the process of buying Bitcoin (the purchase). Users do not need to make a bank transaction every time they do a Bitcoin purchase. They first fund their account manually on their own terms, and the recurring purchases are debited from their pre-funded account balance.
Another approach would have been to automatically withdraw fiat from the user’s bank account (e.g. a direct debit or subscription billing) for each transaction (like our friends at Amber) or to instruct the user to set-up recurring payments to Bull Bitcoin from their bank account (like our friends at Bittr). The downside of these strategies is that they require numerous bank transactions which increases transaction fees and the likelihood of triggering fraud and compliance flags at the user’s bank. However, this does remove the user’s need to keep larger amounts of fiat on the exchange and reduces the friction of having to make manual bank payments.
Bull Bitcoin is currently working on a separate “Recurring Funding” feature that will automatically debit fiat from the user’s bank accounts using a separate recurring schedule with a minimum frequency of once a week, with a target of once every two weeks or once a month to match the user’s income frequency. This can, and will, be used in combination from the “Recurring Buy” feature, but both can be used separately.
The ultimate experience that we wish to achieve is that users will automatically set aside, each paycheck (two weeks), a small budget to invest in Bitcoin using the “Recurring Funding” feature which is sufficient to refill their account balance for the next two weeks of daily recurring purchases.
Frequency of transactions
The second important decision was about customizing the frequency of the schedule. We decided to make it “each day” only. This is specifically to ensure users have a large enough sample size and remain consistent which are the two key components to a successful dollar-cost averaging strategy.
A higher amount of recurring transactions (larger sample size) will result in the user’s average acquisition being closer to the actual average Bitcoin price over that period of time. Weekly or monthly recurring purchases can provide the same effectiveness if they are performed over a duration of time which is 7x longer (weekly) or 30x longer (monthly).
It is our belief that the longer the duration of the schedule, the more likely the user is to cancel the recurring buy schedule in order to “buy the dip”. Dollar-cost averaging is boring, and watching sats appear in the wallet every day is a good way to reduce the temptation of breaking the consistency.
We do not force this on users: they can still cancel the schedule if they want and go all-in. We consider it more of a gentle nudge in the right direction.
Frequency of withdrawals (one purchase = one bitcoin transaction)
This is one of the most interesting design choices because it is a trade-off between scalability (costs), privacy and custody. Ultimately, we decided that trust-minimization (no custody) and privacy were the most important at the expense of long-term scalability and costs.
Realistically, Bitcoin network fees are currently low and we expect them to remain low for the near future, although they will certainly increase massively over the long-term. One of the ways we mitigated this problem was to select the smallest possible transaction fee for transactions done in the context of Recurring Buy, separate from regular transaction fees on regular Bitcoin purchases (which, at Bull Bitcoin, are very generous).
Note: users must merge their UTXOs periodically to avoid being stuck with a large amount of small UTXOs in the future when fees become more expensive. This is what makes me most uncomfortable about our solution. I hope to also solve this problem, but it is ultimately something Bitcoin wallets need to address as well. Perhaps an automated tool in Bitcoin wallets which merges UTXOs periodically when the fees are low? Food for thought.
When transaction fees and scalability becomes a problem for us, it will have become a problem for all other small payments on the Bitcoin network, and we will use whatever solution is most appropriate at that time.
It is possible that Lightning Network ends up being the scalability solution, although currently it is logistically very difficult to perform automated payouts to users using Lightning, particularly recurring payouts, which require users to create Bolt11 invoices and to convince other peers in the network to open channels and fund channels with them for inbound capacity.
These are the general trade-offs:
Send a Bitcoin transaction for every purchase (what we do) - Most expensive for the exchange - Most expensive for the user (many UTXOs) - Increases Bitcoin Network UTXOs set - Inefficient usage of block space - Most private - Zero custody risk
Keep custody of the Bitcoin until the schedule is over or when the user requests a withdrawal (what Coinbase does) - No additional costs -No blockchain bloating - Same level of privacy - High custody risk
Batch user transactions together at fixed intervals (e.g. every day) - Slightly lower transaction costs for the exchange - Same costs for the user - Slightly more efficient use of block space - Same level of UTXO set bloating - Much lower level of privacy - Slightly higher custody risk
Single address vs multiple addresses vs HD keys (xpubs)
The final decision we had to make was preventing address re-use and allowing users to provide an HD key (xpub) rather than a Bitcoin address.
Address re-use generally decreases privacy because it becomes possible for third-party blockchain snoops to figure out that multiple Bitcoin transactions are going to the same user. But we must also consider that even transactions are sent to multiple addresses, particularly if they are small amounts, it is highly likely that the user will “merge” the coins into a single transaction when spending from his wallet. It is always possible for users to prevent this using Coinjoin, in which there is a large privacy gain in not re-using addresses compared to using a single address.
It is important to note that this does not decrease privacy compared to regular Bitcoin purchases on Bull Bitcoin outside of “Recurring Buy”. Whether a user has one transaction of $1000 going to a Bitcoin address or 10x$100 going that same Bitcoin address doesn’t reveal any new information about the user other than the fact he is likely using a dollar-cost averaging mechanism. It is rather a missed opportunity to gain more privacy.
Another smaller decision was whether or not we should ask the user to provide all his addresses upfront before being able to activate the schedule, which would completely remove the possibility of address re-use. We ultimately decided that because this process can take a very long time (imagine doing Recurring Buy every day for 365 days) it is better to let the user do this at his own pace, particularly because he may eventually change his Bitcoin wallet and forget to change the addresses in the schedule.
There are also various legitimate use-cases where users have no choice but to re-use the same address . A discussion for another day!
Asking the user to provide an XPUB is a great solution to address re-use. The exchange must dynamically derive a new Bitcoin address for the user at each transaction, which is not really a technical challenge. As far as I can tell, Bittr is the only Bitcoin exchange exchange which has implemented this technique. Kudos!
It is however important that the user doesn’t reuse this XPUB for anything else, otherwise the exchange can track his entire wallet balance and transaction history.
It is worth noting that not all wallets support HD keys or have HD keys by default (e.g. Bitcoin Core). So it is imperative that we offer the option to give Bitcoin addresses. We believe there is a lot of potential to create wallet coordination mechanisms between senders and recipients which would make this process a lot more streamlined.
In the future, we will certainly allow users to submit an XPUB instead of having to manually input a different address. But for now, we wanted to reduce the complexity to a minimum.
Conclusion: personal thoughts
I have a somewhat unique perspective on Bitcoin users due to the fact that I worked at the Bitcoin Embassy for almost 4 years. During this time, I had the opportunity to discuss face-to-face with thousands of Bitcoin investors. One of my favourite anecdotes is a nocoiner showing up at our office in December 2013 with a bag full of cash attempting to buy Bitcoin, “I know how to read a chart”, furious after being turned away. Many people who went “all-in” for short-term gains (usually altcoins) would show up to the Bitcoin Embassy office months later with heart-breaking stories.
This isn’t what I signed up for. My goal is to help people opt-out of fiat and, ultimately, to destroy the fiat currency system entirely.
This instilled in me a deep-rooted concern for gambling addiction and strong aversion to “trading”. I do not believe that Bitcoin exchanges should blindly follow “what the market dictates”. More often than not, what dictates the market is bad habits users formed because of the other Bitcoin services they used in the past, what other people are used to, and what feels familiar. Running a Bitcoin company should be inseparable from educating users on the best practices, and embedding these best practices into the user experience is the best way for them to learn.
Another important anecdote which motivated me to build a dollar-cost averaging tool is a person very close to me that had made the decision to buy Bitcoin, but was so stressed out about when was the right time to buy that they ended up not buying Bitcoin for a whole 6 months after funding their Bull Bitcoin account. That person eventually gave up and ultimately invested a large amount all at once. In hindsight, it turned out to be one of the worst possible times to invest in Bitcoin during that year.
Investing in Bitcoin can, and should be, a positive and rewarding experience.
Buying Bitcoin every day is the right strategy, but it is not necessarily lead to the best outcome.
The reality is that the best time to buy Bitcoin is at when market hits rock bottom (obviously). Sometimes, the upside from buying the dip can be much bigger than the risk (e.g. when the price dropped below $200 in 2015). But these are exceptions rather than the rule. And the cost of chasing dips is very high: stress, investing time and mental energy, and the very real psychological trauma which results from making bad trading decisions. Ultimately, it’s better to do the right thing than being lucky, but it’s not always a bad idea to cheat on your dollar-cost averaging from time to time if you can live with the costs and consequences.
Yours truly,
Francis

Harmony One [Part 2]

Harmony Protocol
This is a continuation of the thread here https://www.reddit.com/CryptoMoonShots/comments/ezpn0j/harmony_one/. As some of you have requested for more information on Harmony. Here you go:
What is Harmony?
Harmony is a sharded blockchain, similar to Ethereum 2.0, but with several differences e.g. randomness algorithm, consensus mechanism and etc. Currently, Harmony mainnet contains 4 shards and a total of 1,000 validator nodes. Out of the 1,000 nodes, 680 of them are operated by Harmony team and 320 of them are operated by external validators including our foundational node runners.
The 4 shards are indexed with 0, 1, 2, 3 respectively and shard 0 is the beacon chain. Right now, the nodes in shard 1, 2, and 3 are synchronizing and maintaining an updated copy of shard 0 (beacon chain) in preparation for the upcoming features such as cross-link verification and staking.
Reference: https://nodes.harmony.one/harmony-overview/mainnet
Why sharding is key?
To solve the scalability problem without sacrificing security and decentralisation.
“Given Ethereum and Bitcoin’s performance limitations, many blockchain projects proposed various solutions that attempt to increase transaction throughput. Various blockchains proposed to replace Proof-of-Work (PoW) consensus with Proof-of-Stake (PoS) consensus. Other blockchains like EOS use Delegated Proof of Stake (DPoS), where block proposers are elected by voting rather than by an on-chain algorithmic process. Projects like IOTA replaced the chain-of-blocks data structure with a DAG (Directed Acyclic Graph) data structure, which breaks the limitation of sequential processing of transactions.
However, these proposed solutions cannot make significant performance gains without sacrificing other critical aspects, such as security and decentralization. The scalability solution that both preserves security and decentralization is sharding, which creates multiple groups (i.e. shards) of validators and lets them process transactions concurrently. As a result, the total transaction throughput increases linearly as the number of shards grows”
Reference: https://harmony.one/whitepaper.pdf
Current status?
Mainnet with 4 shards launched in June 2019
Mainnet token swap with exchanges ongoing
Open staking on testnet
Reference: https://medium.com/harmony-one/harmony-milestones-2020-1-highlights-and-lowlights-36dea37a271b
Competitors?
Ethereum
Eth 2.0 Phase 0: Launch of Beacon chain for POS with no smart contract functionalities (expected 30 July 2020)
Eth 2.0 Phase 1: Launch of shard chains with verifiable delay functions (unknown timeline)
Eth 2.0 Phase 2: eWASM new Ethereum virtual machine for sharded blockchain (unknown timeline)
Eth 2.0 Phase 3: Continued improvement e.g. cross-shard transactions, light-weight clients, super-square charting and closer ties (unknown timeline)
Optimistically speaking, you can probably get the official launch of phase 1 by mid/end of Year 2021.
Reference: https://www.bitcoinsuisse.com/outlook/ethereum-and-its-transition-to-ethereum-2/
Reference: https://medium.com/swlh/a-comprehensive-view-of-ethereum-2-0-serenity-5865ad8b7c62
Reference: https://docs.ethhub.io/otheethereum-2.0-ama/
Other competitors like Elrond and Multivac still do not have their full mainnet launch with their own blockchain tokens.
Conclusion
Sharded blockchain is complex and no project has managed to implement network, transaction and state sharding. Harmony will be the first working sharded blockchain to do so as compared to the unknown timeline for Eth 2.0 Phase 1.
Harmony is a team of infrastructure engineers in Silicon Valley, now with 4 PhD’s, 8 ex-Google/Amazon/Apple/Facebook, 2 Harvard MBAs, and Stanford/Berkeley AI graduates (reference: https://medium.com/harmony-one/welcome-9-new-harmonauts-to-team-24d71ee8d79b). I believe they have the experience, brains and technical competency to roll out the sharded blockhain.
As mentioned by one community member, “The advanced test beds leading the way before the established chains, this will attract more developers, interest and investment.”
With its first-mover advantage, I am excited to see how this platform will influence the adoption of blockchain technology by other companies.
Disclaimer: I am still holding my stack at 60 sat. I did not take participate in the IEO. Recently bought a small amount at 60 sat. Never invest money that you cannot afford to lose. 😊

/r/Bitcoin FAQ - Newcomers please read

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For some more great introductory videos check out Andreas Antonopoulos's YouTube playlists, he is probably the best bitcoin educator out there today. Also have to give mention to James D'Angelo's Bitcoin 101 Blackboard series. Lots of additional video resources can be found at the videos wiki page or /BitcoinTV.
Key properties of bitcoin
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.

Other blockchains like EOS use Delegated Proof of Stake (DPoS), where block proposers are elected by voting rather than by an on-chain algorithmic process. Projects like IOTA replaced the chain-of-blocks data structure with a DAG (Directed Acyclic Graph) data structure, which breaks the limitation of sequential processing of transactions.
However, these proposed solutions cannot make significant performance gains without sacrificing other critical aspects, such as security and decentralization. The scalability solution that both preserves security and decentralization is sharding, which creates multiple groups (i.e. shards) of validators and lets them process transactions concurrently. As a result, the total transaction throughput increases linearly as the number of shards grows”

Competitors?
Ethereum
Eth 2.0 Phase 0: Launch of Beacon chain for POS with no smart contract functionalities (expected 30 July 2020)
Eth 2.0 Phase 1: Launch of shard chains with verifiable delay functions (unknown timeline)
Eth 2.0 Phase 2: eWASM new Ethereum virtual machine for sharded blockchain (unknown timeline)
Eth 2.0 Phase 3: Continued improvement e.g. cross-shard transactions, light-weight clients, super-square charting and closer ties (unknown timeline)
Optimistically speaking, you can probably get the official launch of phase 1 by mid/end of Year 2021.

Other competitors like Elrond and Multivac still do not have their full mainnet launch with their own blockchain tokens.
Technical analysis?
Satoshi level remains consistent at 60+ sat level. Accumulation at this level for already close to 7 weeks. Lowest low is around 52 sat. No pump yet as it is largely neglected while other coins are pumping massively.
Token details
Current Market cap (CMC): $30m
Current price: 0.006048 (around 1.9x from IEO)
IEO price: 1 ONE = 0.003175 USD
Current supply: 4,977,696,588 (see link below)
Unlock schedule:
https://docs.google.com/spreadsheets/d/143qpsVaezh9sY_pDhNK-cffwgEdRojWa38-rqBwKI7c/edit
Max supply: 12,600,000,000
Assume fully diluted market cap (DMC): $76m (12,600,000,000 x 0.006048)
My target market cap: $300m (to match platforms like Qtum, ICX, vechain) (10x from current CMC) (4 x from DMC). Key catalyst that may propel token price to this market cap would be (speculative):
  1. Binance’s strong support for its IEO. Highly likely that Binance would want to shill its successful IEO when open staking is ready (especially it is the first platform with network, transaction and state sharding)
  2. Partnerships (both in SF and China) and Defi projects
Conclusion
Sharded blockchain is complex and no project has managed to implement network, transaction and state sharding. Harmony will be the first working sharded blockchain to do so as compared to the unknown timeline for Eth 2.0 Phase 1.
Harmony is a team of infrastructure engineers in Silicon Valley, now with 4 PhD’s, 8 ex-Google/Amazon/Apple/Facebook, 2 Harvard MBAs, and Stanford/Berkeley AI graduates (reference: https://medium.com/harmony-one/welcome-9-new-harmonauts-to-team-24d71ee8d79b). I believe they have the experience, brains and technical competency to roll out the sharded blockhain.
As mentioned by one community member, “The advanced test beds leading the way before the established chains, this will attract more developers, interest and investment.”
With its first-mover advantage, I am excited to see how this platform will influence the adoption of blockchain technology by other companies.
Disclaimer: I did not take participate in the IEO. Recently bought a small amount at 60 sat. Never invest money that you cannot afford to lose.

Looking back 18 months.

I was going through old emails today and came across this one I sent out to family on January 4, 2018. It was a reflection on the 2017 crypto bull market and where I saw it heading, as well as some general advice on crypto, investment, and being safe about how you handle yourself in cryptoland.
I feel that we are on the cusp of a new bull market right now, so I thought that I would put this out for at least a few people to see *before* the next bull run, not after. While the details have changed, I don't see a thing in this email that I fundamentally wouldn't say again, although I'd also probably insist that people get a Yubikey and use that for all 2FA where it is supported.
Happy reading, and sorry for some of the formatting weirdness -- I cleaned it up pretty well from the original email formatting, but I love lists and indents and Reddit has limitations... :-/
Also, don't laught at my token picks from January 2018! It was a long time ago and (luckliy) I took my own advice about moving a bunch into USD shortly after I sent this. I didn't hit the top, and I came back in too early in the summer of 2018, but I got lucky in many respects.
----------------------------------------------------------------------- Jan-4, 2018
Hey all!
I woke up this morning to ETH at a solid $1000 and decided to put some thoughts together on what I think crypto has done and what I think it will do. *******, if you could share this to your kids I’d appreciate it -- I don’t have e-mail addresses, and it’s a bit unwieldy for FB Messenger… Hopefully they’ll at least find it thought-provoking. If not, they can use it as further evidence that I’m a nutjob. 😉
Some history before I head into the future.
I first mined some BTC in 2011 or 2012 (Can’t remember exactly, but it was around the Christmas holidays when I started because I had time off from work to get it set up and running.) I kept it up through the start of summer in 2012, but stopped because it made my PC run hot and as it was no longer winter, ********** didn’t appreciate the sound of the fans blowing that hot air into the room any more. I’ve always said that the first BTC I mined was at $1, but looking back at it now, that’s not true – It was around $2. Here’s a link to BTC price history.
In the summer of 2013 I got a new PC and moved my programs and files over before scrapping the old one. I hadn’t touched my BTC mining folder for a year then, and I didn’t even think about salvaging those wallet files. They are now gone forever, including the 9-10BTC that were in them. While I can intellectually justify the loss, it was sloppy and underlines a key thing about cryptocurrency that I believe will limit its widespread adoption by the general public until it is addressed and solved: In cryptoland, you are your own bank, and if you lose your password or account number, there is no person or organization that can help you reset it so that you can get access back. Your money is gone forever.
On April 12, 2014 I bought my first BTC through Coinbase. BTC had spiked to $1000 and been in the news, at least in Japan. This made me remember my old wallet and freak out for a couple of months trying to find it and reclaim the coins. I then FOMO’d (Fear Of Missing Out”) and bought $100 worth of BTC. I was actually very lucky in my timing and bought at around $430. Even so, except for a brief 50% swing up almost immediately afterwards that made me check prices 5 times a day, BTC fell below my purchase price by the end of September and I didn’t get back to even until the end of 2015.
In May 2015 I bought my first ETH at around $1. I sent some guy on bitcointalk ~$100 worth of BTC and he sent me 100 ETH – all on trust because the amounts were small and this was a small group of people. BTC was down in the $250 range at that point, so I had lost 30-40% of my initial investment. This was of the $100 invested, so not that much in real terms, but huge in percentages. It also meant that I had to buy another $100 of BTC on Coinbase to send to this guy. A few months after I purchased my ETH, BTC had doubled and ETH had gone down to $0.50, halving the value of my ETH holdings. I was even on the first BTC purchase finally, but was now down 50% on the ETH I had bought.
The good news was that this made me start to look at things more seriously. Where I had skimmed white papers and gotten a superficial understanding of the technology before FOMO’ing, I started to act as an investor, not a speculator. Let me define how I see those two different types of activity:
So what has been my experience as an investor? After sitting out the rest of 2015 because I needed to understand the market better, I bought into ETH quite heavily, with my initial big purchases being in March-April of 2016. Those purchases were in the $11-$14 range. ETH, of course, dropped immediately to under $10, then came back and bounced around my purchase range for a while until December of 2016, when I purchased a lot more at around $8.
I also purchased my first ICO in August of 2016, HEAT. I bought 25ETH worth. Those tokens are now worth about half of their ICO price, so about 12.5ETH or $12500 instead of the $25000 they would be worth if I had just kept ETH. There are some other things with HEAT that mean I’ve done quite a bit better than those numbers would suggest, but the fact is that the single best thing I could have done is to hold ETH and not spend the effort/time/cost of working with HEAT. That holds true for about every top-25 token on the market when compared to ETH. It certainly holds true for the many, many tokens I tried to trade in Q1-Q2 of 2017. In almost every single case I would have done better and slept better had I just held ETH instead of trying to be smarter than Mr. Market.
But, I made money on all of them except one because the crypto market went up more in USD terms than any individual coin went down in ETH or BTC terms. This underlines something that I read somewhere and that I take to heart: A rising market makes everyone seem like a genius. A monkey throwing darts at a list of the top 100 cryptocurrencies last year would have doubled his money. Here’s a chart from September that shows 2017 year-to-date returns for the top 10 cryptocurrencies, and all of them went up a *lot* more between then and December. A monkey throwing darts at this list there would have quintupled his money.
When evaluating performance, then, you have to beat the monkey, and preferably you should try to beat a Wall Street monkey. I couldn’t, so I stopped trying around July 2017. My benchmark was the BLX, a DAA (Digital Asset Array – think fund like a Fidelity fund) created by ICONOMI. I wasn’t even close to beating the BLX returns, so I did several things.
  1. I went from holding about 25 different tokens to holding 10 now. More on that in a bit.
  2. I used those funds to buy ETH and BLX. ETH has done crazy-good since then and BLX has beaten BTC handily, although it hasn’t done as well as ETH.
  3. I used some of those funds to set up an arbitrage operation.
The arbitrage operation is why I kept the 11 tokens that I have now. All but a couple are used in an ETH/token pair for arbitrage, and each one of them except for one special case is part of BLX. Why did I do that? I did that because ICONOMI did a better job of picking long-term holds than I did, and in arbitrage the only speculative thing you must do is pick the pairs to trade. My pairs are (No particular order):
I also hold PLU, PLBT, and ART. These two are multi-year holds for me. I have not purchased BTC once since my initial $200, except for a few cases where BTC was the only way to go to/from an altcoin that didn’t trade against ETH yet. Right now I hold about the same 0.3BTC that I held after my first $100 purchase, so I don’t really count it.
Looking forward to this year, I am positioning myself as follows:
Looking at my notes, I have two other things that I wanted to work into this email that I didn’t get to, so here they are:
  1. Just like with free apps and other software, if you are getting something of value and you didn’t pay anything for it, you need to ask why this is. With apps, the phrase is “If you didn’t pay for the product, you are the product”, and this works for things such as pump groups, tips, and even technical analysis. Here’s how I see it.
    1. People don’t give tips on stocks or crypto that they don’t already own that stock or token. Why would they, since if they convince anyone to buy it, the price only goes up as a result, making it more expensive for them to buy in? Sure, you will have friends and family that may do this, but people in a crypto club, your local cryptocurrency meetup, or online are generally not your friends. They are there to make money, and if they can get you to help them make money, they will do it. Pump groups are the worst of these, and no matter how enticing it may look, stay as far away as possible from these scams. I even go so far as to report them when I see them advertise on FB or Twitter, because they are violating the terms of use.
    2. Technical analysis (TA) is something that has been argued about for longer than I’ve been alive, but I think that it falls into the same boat. In short, TA argues that there are patterns in trading that can be read and acted upon to signal when one must buy or sell. It has been used forever in the stock and foreign exchange markets, and people use it in crypto as well. Let’s break down these assumptions a bit.
i. First, if crypto were like the stock or forex markets we’d all be happy with 5-7% gains per year rather than easily seeing that in a day. For TA to work the same way in crypto as it does in stocks and foreign exchange, the signals would have to be *much* stronger and faster-reacting than they work in the traditional market, but people use them in exactly the same way.
ii. Another area where crypto is very different than the stock and forex markets centers around market efficiency theory. This theory says that markets are efficient and that the price reflects all the available information at any given time. This is why gold in New York is similar in price to gold in London or Shanghai, and why arbitrage margins are easily <0.1% in those markets compared to cryptoland where I can easily get 10x that. Crypto simply has too much speculation and not enough professional traders in it yet to operate as an efficient market. That fundamentally changes the way that the market behaves and should make any TA patterns from traditional markets irrelevant in crypto.
iii. There are services, both free and paid that claim to put out signals based on TA for when one should buy and sell. If you think for even a second that they are not front-running (Placing orders ahead of yours to profit.) you and the other people using the service, you’re naïve.
iv. Likewise, if you don’t think that there are people that have but together computerized systems to get ahead of people doing manual TA, you’re naïve. The guys that I have programming my arbitrage bots have offered to build me a TA bot and set up a service to sell signals once our position is taken. I said no, but I am sure that they will do it themselves or sell that to someone else. Basically they look at TA as a tip machine where when a certain pattern is seen, people act on that “tip”. They use software to see that “tip” faster and take a position on it so that when slower participants come in they either have to sell lower or buy higher than the TA bot did. Remember, if you are getting a tip for free, you’re the product. In TA I see a system when people are all acting on free preset “tips” and getting played by the more sophisticated market participants. Again, you have to beat that Wall Street monkey.
  1. If you still don’t agree that TA is bogus, think about it this way: If TA was real, Wall Street would have figured it out decades ago and we would have TA funds that would be beating the market. We don’t.
  2. If you still don’t agree that TA is bogus and that its real and well, proven, then you must think that all smart traders use them. Now follow that logic forward and think about what would happen if every smart trader pushing big money followed TA. The signals would only last for a split second and would then be overwhelmed by people acting on them, making them impossible to leverage. This is essentially what the efficient market theory postulates for all information, including TA.
OK, the one last item. Read this weekly newsletter – You can sign up at the bottom. It is free, so they’re selling something, right? 😉 From what I can tell, though, Evan is a straight-up guy who posts links and almost zero editorial comments.
Happy 2018.

Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
