Hi there!

The world of crypto has a completely different set of words and jargon from what we use in everyday life. A newcomer in this field will usually feel out of place and might not understand what is happening because of how different and technical the terms are. We have prepared this Glossary to serve as a quick reference to guide for you. This is a living document and will constantly be updated to reflect the fast-paced world of Crypto.
  • 2FA

    - is short for 2 factor authentication. it is another step of verification other than your standard username and password that makes hacking into your account harder. A good example of this is the Google Authenticator which is used in many websites and services.
  • address

    - a bunch of alphanumeric characters, which are created uniquely for each individual. These addresses are then used to send or receive cryptocurrency.
  • addy

    - another term of address
  • altcoin

    - a cryptocurrency term for coins other than Bitcoin
  • ATH

    - an acronym for “All Time High,” which is often used when the price of a token or a currency has peaked.
  • ASIC

    - an acronym for "Application Specific Integrated Circuit." These are silicon chips specifically designed to do a single task and nothing else. A good example of an ASIC is the ASIC miners in Bitcoin. These have replaced GPUs since ASICs can mine Bitcoin faster and more efficiently than GPUs. Not all coins support ASICs because some have built-in ASIC protection to prevent ASICs from being used to mine.
  • bag holder

    - an investor who is hodling a cryptocurrency for a long time but its value has decreased and become almost worthless.
  • bear market

    - refers to a market that is in decline. An example could be share/token prices that are continuously dropping, resulting in a continued long-term downward trend.
  • BIP

    - an abbreviation for “Bitcoin Improvement Proposal.” Anyone with a good idea on how to improve Bitcoin’s network can submit their idea and it is voted upon. If this passes the voting stage, it is then rolled out to be decided upon by miners switching over to the new BIP.
  • Bitcoin

    - The first decentralized crypotocurrency. Developed by the mysterious Satoshi Nakamoto. It is the most popular cryptocurrency as of now. more info can be found on
  • block reward

    - the reward given to a miner for hashing an algorithm.
  • blockchain

    - an incorruptible digital ledger for economic transactions that can be programmed to record anything of value. The record of the transaction that was made can be fully public for public blockchains or private in the case of private blockchains.
  • blocks

    - are packs of data or information that pass through the blockchain; it is similar to a page of a ledger that contains records of transactions.
  • Bollinger band

    - a margin around the price of a cryptocurrency that determines if a coin/token is oversold or overbought.
  • bull market

    - is the opposite of a bear market; refers to a market with prices of shares, commodities or tokens that are constantly or steadily rising leading to a long-term upward trend.
  • central ledger

    - also known as a general ledger where all the records are stored and controlled by a singular network or an individual; it is the backbone of any accounting system.
  • cold storage

    - refers to the concept of keeping reserved cryptocurrency away from the internet to keep it safe from hacking. An example of this is using a hardware wallet to store Ethereum or Bitcoin. Other methods include using a paper wallet, or by purposely keeping a computer holding the currency away from the internet.
  • confirmation

    - a state where a process or transaction has been encoded or written onto the immutable ledger called the blockchain; requires miners to validate a transaction.
  • consensus

    - is when all participants of the network or blockchain come into terms on the validity of the transaction, making sure that all ledgers pertaining to a certain transaction are the same.
  • crowdsale

    - the act of offering tokens for sale to the general public. Crowdsales usually have lower minimum purchase requirements than presale but lower discounts.
  • DAO

    - is short for “Decentralised Autonomous Organization”. These are organizations or corporations governed by a set of rules written in code that run without any human involvement which decreases the chance of the influence human error inside the DAO.
  • DApp

    - an abbreviation for Decentralized Application. These are applications that are open-sourced where information doesn’t come from a central point or a server. Instead, it comes from people providing other people the information, services or computing power that they seek. A good example of this is a torrent. When you visit a torrent site and search for something to torrent, you don’t download the file from a central server but instead from other people sharing that information publicly.
  • double spend

    - an attack on a blockchain where a set of coins is sent to two people at the same time. This can be done by sending two transactions to different people or addresses at exactly the same time but has largely been mitigated in the latest updates.
  • distributed ledger

    - a ledger that is shared across networks and CPUs since the data is agreed upon to be shared and replicated.
  • escrow contract

    - also known as an escrow agreement is when one party deposits an asset with a third party who then turns in the said asset to another party when a certain term or condition is reached. This effectively lessens the risk that one party will not perform as per agreement and will just run off with the payment.
  • ETH, ethereum

    - one of the most popular cryptocurrencies. Ethereum is a decentralized platform that runs smart contracts on a custom built blockchain.
  • exchange

    - online cryptocurrency exchanges are websites where you can buy, sell and trade cryptocurrency for other cryptocurrencies and currencies (USD, EUR, etc.).
  • flat

    - is government-approved legal tender that is not backed by precious metals or commodity. Its money is derived from supply and demand rather than the value of the material that the money is backed by. Fiat can simply be printed by a central bank and with it comes issues about its value deflating over time since it is not backed by real assets.
  • The Flippening

    - refers to a possible future event when Ethereum or any other cryptocurrency overtakes Bitcoin to become the most valuable, highest hash rate, or highest market cap cryptocurrency. During the 3rd week of November 2017, a Flipping event was attempted by miners of Bitcoin Cash which almost dethroned Bitcoin.
  • FoMo

    - is an abbreviation of “Fear of Missing out.” One feels anxious when he or she doesn’t want to be left out of the success that others are experiencing from an investment. FoMo is said to be an investor’s worst enemy since it is a counter-productive thought that can lead to irrational decision-making.
  • FUD

    - is an abbreviation for Fear, Uncertainty and Doubt. It can come to us naturally or it can also be pushed onto us by others seeking to undermine the price of a certain stock, token or commodity.
  • fork

    - is what happens when a blockchain diverges into two potential paths. The most famous example is when Bitcoin Split into Bitcoin and Bitcoin Cash on August 1, 2017.
  • fork

    - is what happens when a blockchain diverges into two potential paths. The most famous example is when Bitcoin Split into Bitcoin and Bitcoin Cash on August 1, 2017.
  • gas

    - payment for computation done on the Ethereum blockchain. Everything you do requires gas to pay for the miners executing a smart contract, transferring ETH and other activities. A good explanation of gas, gas limit and gas price is from MyEtherWallet’s explanation page.

  • GPU

    - is short for Graphics Processing Unit; traditionally used to enable PCs to display advanced graphics for gaming but they have also been repurposed for use to mine cryptocurrency.
  • halving

    - Twenty-one million Bitcoins will only ever be issued. The limited number of bitcoins issued was created to counteract the endless printing of paper currencies which leads to inflation. Each time a new block is added to the bitcoin network, bitcoins are awarded to miners that discover that new block. Initially, the reward was set to 50 BTC but it was reduced to only 25 BTC in 2012. Every four years, this reward will continue to halve. This event is called halving.
  • hard fork

    - a drastic change in the blockchain environment that often entails switching over to a new version of a blockchain and disregarding the old one. Hard forks are usually done when a major change needs to be implemented onto a blockchain. Transactions on nodes that have not upgraded to the new version are invalidated and only transactions on the newer version are considered by the network as valid. There will usually be for a time two blockchains running in parallel, one on the old version and one on the new until such time that all nodes or miners switch over to the new blockchain.
  • hardware wallet

    - a special type of wallet that stores a user’s private keys in a hardware device to avoid getting hacked of sensitive information. Some popular hardware wallets are Trezor, Ledger Wallet and Keepkey.
  • hash rate (or hashrate)

    - the strength in which a miner’s rig can dish out to mine for Bitcoins; the measurement for the processing capability of the Bitcoin network.
  • HODL

    - an intentional misspelling of the word “hold” that originated from a 2013 Bitcoin forum. Investors that suggest hodling keep their coins for a long time with the belief that it will have a higher value one day. HODL is also now (humorously) known as “hold on for dear life.”
  • hot wallet

    - a type of wallet that is constantly connected to the internet. It is not recommended that hot wallets hold big amounts of cryptocurrency because they can be hacked. Instead just leave enough cryptocurrency for your daily needs or trades in the hot wallet.
  • ICO

    - an abbreviation for initial coin offering. This is the cryptocurrency equivalent of an initial public offering (IPO) or crowdsourcing. ICOs sell their currency or tokens to fund a project. Before buying into an ICO, some rules apply, which vary from ICO to ICO. Due diligence is recommended before buying in.
  • IOTA

    - the open source distributed ledger that does not make use of blockchain; may also refer to the cryptocurrency.
  • Lambo/Lambo land

    - short for Lamborghini; means making it big in Crypto. It is sort of a meme in the crypto community where if you earn enough money to buy a Lambo you have made enough profits to live a very comfortable life.
  • long or going long

    - the state of owning a particular cryptocurrency token, coin or a share of stock also can refer to holding a stock or token for a long time.
  • MACD

    - an acronym for Moving Average Convergence Divergence. Is a visual indicator that presents the relationship of 3 exponential moving averages.

  • market order/buy/sell

    - any order/purchase/sale at the current price executed on an exchange
  • margin trading

    - a highly risky strategy of borrowing coins and paying interest to increase the invested amount without actually holding any assets; only permitted for investors that meet rigid criteria.
  • mining

    - if Bitcoin or other forms of coins are being compared to gold due to their limited supply, mining is the process of obtaining them. However, instead of using heavy machines to burrow underground, computing power or hashing power of GPUs, ASICs or CPUs are used to validate blockchain transactions, provide proof of work and run code. Miners also their processing power to mine the next block, which is rewarded in the form of coins. Mining is essential to the stability of the blockchain because in addition to discovering blocks, miners are also the ones who write transactions on the digital ledger or blockchain.
  • mining rig

    - a computer that has multiple GPUs that is used for mining.
  • multi-signature

    - also known as multisig; refers to requiring more than one key to authorize a transaction or a withdrawal from a wallet. This prevents any one person from taking the funds for himself without the knowledge or consensus of other members of the organization.
  • moon

    - a term used by the crypto community when projecting an increase in a coin’s value. Also synonymous with go up.
  • moon mission

    - a term used when multiple people have a collective goal of increasing the value of a commodity, token or coin.
  • node

    - a crypto wallet software that maintains a complete and up-to-date digital ledger that matches the current state of the blockchain. The more nodes in a blockchain, the safer it is from attacks.
  • paper wallet

    - a document containing all the data needed to generate a private key. It is also used as a way to store tokens or coins outside a computer. Some good sites for generating paper wallets for bitcoin are:, and
  • permission ledger

    - a type of ledger that requires access details from any user; access is limited to certain users due to data privacy.
  • private key

    - the key to an online wallet. Holding a private key is as good having complete control over a wallet. A good example of this is a QR code, some online wallets make you print out your unique QR code in order for you to access or recover your online wallet in the future.
  • Proof of Work (PoW)

    - a type of algorithm where miners are rewarded for the amount of work done. PoW is like working per hour where one gets rewarded for the amount of work performed for a particular period. It utilizes a system where it is difficult to forge the amount of work done but is easy to check if the work done is authentic. Most coins use proof of work since mining is central to keeping the blockchain alive and transactions flowing where miners write and validate entries onto the blockchain.
  • Proof of Stake (PoS)

    - an algorithm where rewards and consensus is based upon the number of tokens or coins you hold. Where the more tokens or coins you hold for a longer time, the more valuable your node is because there is a higher chance of your node finding the correct block.
  • public key

    - a wallet address that one can share with people in order to send payments to an address or payments to theirs. This is similar to an email address on Paypal where you can give your email to a person that would be sending money over to your account.
  • public ledger

    - a type of ledger that is distributed to all online users, an example of which is Bitcoin’s ledger.
  • pump and dump

    - a type of market manipulation that involves inflating the price of a stock or a token/coin with the intent of immediately selling it for a huge profit. This scheme usually involves social manipulation with news or rumors being spread to hype up a coin. This is usually coupled with increased buy activity for the particular token/coin in order to give the illusion that a bull run is taking place.
  • presale

    - a sale held before a crowdsale; the tokens/coins sold in a presale are usually discounted more so than in crowdsale as the risk in investing in a startup is higher. In some ICOs, the minimum purchase amount for presale is also larger than in crowdsale. Presale is often confused with private sale since they are held before a crowdsale; the former is open to the public whereas the latter is not.
  • private sale

    - is similar to a presale in terms since it is held before a crowdsale. The difference is that in a private sale, the ICO usually offers tokens or coins to wealthy or well-known people or organizations. Private sales are usually not open to the public and the ICO chooses who to sell its tokens to.
  • rekt

    - a misspelling of “wrecked”. Used to describe an investor who has suffered from losses due to a reduction in the value of a particular cryptocurrency.
  • satoshi

    - the smallest unit of Bitcoin

  • short or going short

    - trading by margin where the investment earns a profit when the price of a cryptocurrency or stock decreases.
  • signature

    - a mathematical operation used to indicate ownership by an individual to a coin, wallet or data; these are private and known only by the owner.
  • soft work

    - refers to adding in new capabilities or commands onto an existing blockchain without invalidating older transactions. It differs from a hard fork in that only previously valid transactions are made invalid. Since old nodes recognize the new blocks as valid, a soft fork is essentially backward-compatible. This type of fork requires most miners upgrading in order to enforce, while a hard fork requires all nodes to agree on the new version.
  • software wallet

    - a software file or program that acts as cryptocurrency storage.
  • smart contract

    - is a set of rules for business or economic activity written in code that is processed by the blockchain to achieve a desired outcome. Smart contracts usually function without need for human intervention. A good example is a simple sale of tokens where the seller sends tokens to the purchaser once payment has been received. It is one of the defining features of Ethereum.
  • stable coin

    - a cryptocurrency with very low volatility that is used for market trading.
  • staking

    - the act of owning or holding particular tokens or coins to generate profits, and help validate blocks. This applies in general to a Proof of Stake system.
  • TCP/IP

    - an acronym that stands for Transmission Control Protocol or Internet Protocol. This a standard that specifies how data is exchanged over the internet.
  • Technical Analysis (TA)

    - or Trend Analysis; the art and science of analyzing patterns in the market to make predictions about future movements. Where if future market performance can be predicted, one can make a profit out of this knowledge.
  • This is it gentlemen

  • token

    - the term for any project’s currency that is built on a blockchain; tokens are issued to fund the project.
  • total supply

    - the maximum number of tokens or coins existing.
  • transaction fee

    - paid out to facilitate the transfer of money or cryptocurrency from one wallet to another. In Bitcoin, this transaction fee is deducted by miners from the amount being sent, which constitutes to a lesser amount for the recipient. Ethereum decoupled the transaction fee by implementing the Gas which is the amount of ETH paid to miners to transfer ETH from one wallet to another.
  • Turing complete

    - a system that is capable of performing calculations and transactions that any computer can accomplish. Ethereum is described as a Turing complete system and is often said to be a “World Computer.”
  • Vitalik Buterin

    - the most popular co-founder of Ethereum who also serves as an advisor to several ICOs.
  • volatility

    - refers to the amount of instability in a market. Periods of high volatility mean that prices of a certain token or currency may swing up and down by huge amounts. Low volatility means that prices of a certain token or currency trade within a tight range.
  • wallet
