Help to make this website better! If you found any missing words, or you have nicer/precise definitions for certain terms, let us know and send us an email to so we can update this list.


Accumulation : Accumulation means to buy as many coins as possible at the lowest possible price. It is often claimed that →Whales projects →fudden to accumulate as many coins as possible at a low price.

Airdrop: An Airdrop refers to the distribution of free → coins. New projects sometimes give away some of their coins to promote their product. For some Airdrops you have to actively do tasks to get them. Sites like Airdropking are specialized in finding the latest Airdrops.

All Time High (ATH): When a Coin reaches its all time high, it means that it has reached its highest price level so far.

Altcoin: Alt or Altcoin is a collective term for all →Coins (except →Bitcoin). Since Bitcoin was the first →cryptocurrency, all other coins got the nickname “Altcoin”.

Antminer: An antminer is a popular one, produced by →Bitmain.

Arbitrage: Taking advantage of the fact that →Coin is sometimes offered at different →exchange at the same time at a different price. This is called arbitrage trading.

ASIC: ASIC is short for Application Specific Integrated Circuit. ASICs are → mining devices that work for certain → cryptocurrencies. → Bitcoin and currently → Ethereum can be mined using ASICs. ASICs are often criticized for → centralization, so some projects are trying to make their → Coin ASIC-resistant (not compatible for ASIC devices). An example of such a coin is → Monero.

Ask: The price for which market participants are willing to sell their →Coins.   (opposite: →Bid)

Atomic swap: An atomic swap is a token exchange of two coins located on different → blockchains, which takes place → on-chain. The exchange happens at a predetermined rate and does not require an→ exchange


B2B: B2B is an abbreviation for business to business, in contrast to →P2P or →Peer to Peer

Bag holder: Bagholder is the derogatory term for owners of → coins who have lost a large part of their value since the owner of the coin bought the coin. Bagholders are often accused of → shilling in order to finally → dump → their heavy bags.

Bear(ish): The bear symbolises falling prices, while the →Bulle bull symbolises rising prices. To be bearish means that someone thinks that prices will fall. A bearish market is a market in which prices fall.

BearWhale: The so-called BearWhale is a user unknown to date, who owned at least 36,000 Bitcoin in the years 2013 / 2014. According to his own account, a large part of his lifelong savings was invested at a price of about $8 per BTC. He HODLed these Bitcoins for a long time until the discussion about reducing the blocksize shook his confidence and he decided to sell. On a memorable day in 2014 (October 5), he finally sold 30,000 BTC in a block! at a price of $300 over Bitstamp. This event became famous in the crypto community as the “Battle of BearWhale”.

Confirmations: The more confirmation a transaction has, the more certain one can be that this transaction will be integrated into →Blockchain in the long term. If the →Transaction is sent to the network in a valid block, then this transaction receives 1 confirmation.

If a second block is published, which builds on this first block, then this transaction now has 2 confirmation. If a transaction only exists in →Mempool, but no block has been published yet that holds the transaction, then this transaction has 0 confirmation. Accepting a transaction with 0 confirmation is often considered insecure, because it is easy to donate 0 confirmation to →Double.

Binance: Binance is one of the largest →cryptocurrency exchanges. Register here.

Bid: The price at which market participants are willing to buy a →Coin. (opposite: →Ask))

Bitcoin (maximalist): Bitcoin (BTC) is the oldest → cryptocurrency. It was developed by → Satoshi Nakamoto. Bitcoin is currently the → cryptocurrency with the highest → market capitalization. A Bitcoin maximalist only accepts Bitcoin as the “one, true” → cryptocurrency

Bitcoin cash: Bitcoin Cash (BCH) is a → hard fork of Bitcoin, which promises to increase the → transaction speed of Bitcoin and additionally reduce the → mining fees by increasing the → block size. Increasing the block size has advantages and disadvantages, and it remains to be seen whether this approach is a sensible approach for → scaling.

Bitcoin Cash has not activated → Segwit and does not intend to scale with the → Lightning Network. Bitcoin Cash and Bitcoin both want to bear the name “Bitcoin” and the ticker symbol BTC, since they both claim that they represent the “real” vision of Bitcoin, created by → Satoshi Nakamoto. One of the most influential Bitcoin Cash supporters is → Roger Ver

Bitcointalk: Bitcointalk is the largest discussion forum for cryptocurrencies.

Bitfinex: The Bitfinex is a → cryptocurrency exchange on which → Fiat can be exchanged for → Crypto.

Bitmain: Bitmain is a company that sells hardware for → mining

Bitstamp: The Bitstamp is a → cryptocurrency exchange on which → Fiat can be exchanged for → Crypto.

Block producer: In some → cryptocurrencies, only a few → nodes can publish a → block (for example → EOS). These nodes are called → block producers.

Block Reward: Number of coins →Miner receives for publishing a valid →Blocks if it becomes part of →Blockchain

Blockchain: A block is a collection of → transactions published by a → miner. The goal of every miner is to publish a valid block in order to receive the → Mining Reward and / or the → Mining Fees. The → block size and the average → block time can differ for different cryptocurrencies. Blocks are part of the blockchain.

The concept of blockchain protects cryptocurrencies from hacks and eliminates the possibility of → double spending. The blockchain is so called because the blocks are chained together. If someone wanted to change an old block, he would have to “hack” all new blocks first. This means that the older a block is, the more likely it is that the block will remain a valid and permanent block in the blockchain. Some new → Altcoins do not use the blockchain and secure their network with other mechanisms (→ Nano, → IOTA).

Blockfolio: A popular app to track the current exchange rate of crypto currencies.

Block size: Denotes the size of a → block. Usually the size of a block is between a few kilobytes and a few megabytes. Some cryptocurrencies prefer to have a fixed, small block size (→ Bitcoin), while others prefer to use a larger block size (→ Bitcoin Cash). Some cryptocurrencies use a dynamic block size that can change over time (→ Monero). Still other cryptocurrencies like → IOTA or → Nano don’t have conventional block sizes because they don’t use blockchain technology.

A larger block means that more transactions can be accepted per unit of time, which reduces the → transaction fees and empties the → mempool more quickly. However, large blocks make the → blockchain grow faster, which can lead to → centralization, since fewer people are willing to operate a → full node. Different perspectives on the block size has led to the → hard fork between → Bitcoin and → Bitcoin Cash.

Block Lattice: Block Lattice is an alternative data structure, which promises some advantages over the block chain. For example, a block lattice allows faster →transactions for fewer fees. The block lattice works fundamentally differently than the →Blockchain. This data structure is currently used by the crypto currency →Nano.

Block time: The average time it takes to publish a block. Longer block times result in a lower transaction speed.

Blox: A popular app to track the current exchange rate of cryptocurrencies.

Decentralized: In a decentralized system, the users are linked to each other via →P2P. There is no central authority, with special privileges.  Anyone can join a decentralized network, it is difficult to take offline and – in the best case – almost impossible to hack. A real decentralized network is →trustless

Decentralized autonomous organization: A decentralised autonomous organisation is an organisation which is regulated by →Smart contracts.  The idea of a DAO comes from →Dan Larimer. The hack of the Smart Contracts of the first decentralized autonomous organization  ́The DAO ”. Leads to →Hard Fork of the →Ethereum network. The hard fork is now known as →Ethereum, the old block chain where the hack is still present is known as Ethereum Classic.

Decentralized exchange: A →stock exchange, which is regulated by →Smart Contracts. Decentralized exchanges are in theory cheaper and safer than centralized exchanges. Unfortunately they often have less good design and little Trading→Volume

ERC-20 token: ERC – 20 Token (Ethereum Request for Comment) is a set of standard program code often used to create personalized →Token on →Ethereum →Blockchain as part of a →Smart contract. This functionality is often used by →ICOs. All these tokens can be used in Ethereum compatible →Wallets. Since these →Token use the Ethereum blockchain, you need Ethereum to pay the →Transactions fees for sending the tokens.

Escrow: Escrow payment means that the coins are held by a third party until both the buyer and the seller signal that the purchase/sale has gone smoothly. If there are any problems with the transaction, the third party will decide whether the buyer or the seller will get the money back.

The Ethereum Blockchain hosts many →dApps and →Smart contracts. →Smart Contracts must be written on the Ethereum Blockchain in the programming language →Solidity. The consensus algorithm is →POW and not →ASIC resistant.

However, the →Casper update will cause an →Hardfork of the Ethereum network and then make Ethereum a →POS block chain. The →Blockzeit is faster than the block time of →Bitcoin. The currency of the Ethereum block chain is Ether.

Etherscan: Etherscan is a popular →Ethereum →Blockchain explorer. A software that allows you to search the Ethereum block grove for transactions

Exit scam: Exit scamming (= cheating by running away). Exit scammers get people to give them money. Mostly they promise the money lenders fantastic profit expectations.

Gas limit is the maximum number of Gwei that you want to spend on the transaction. Complicated calculations require a higher gas limit. Increasing the gas limit will not make the Ethereum transaction faster.

Genesis Block/Account: The Genesis block is the name of the first →Block of a →Blockchain. Genesis accounts are the accounts of the first owner of a coin.

Github: A popular website for uploading computer code and working together on it.

GPU: Graphics processing unit is a hardware part in a normal computer. GPUs are usually more powerful than CPUs and are therefore sometimes still used for →Mining, especially in coins that are →ASIC-resistant.

Gwei: 1 Gwei denotes 0,000 000 001 (1×10^-9) ether. 1 Gwei is therefore 10^9 Wei. The →Gas price is paid in Gwei and increasing it enhances the speed of a →Ethereum transaction.


Halving: The → Bitcoin → block reward is halved every 4 years, which leads to decreasing inflation. This event is known as “The Halvening”. The time until the next halvening can be seen here.

Hardcap: Hardcap usually refers to the maximum number of coins that an ICO will create/sell. Once an ICO project has reached its hardcap it will not sell any more tokens. Sometimes hard cap also refers to the maximum number of coins that can ever be put into circulation. For example, the hardcap for →Bitcoin is approximately 21 million BTC.

Hardfork: A hardfork is a →Fork where not all nodes accept the new software and some nodes continue to use the old software. A hard fork creates a “new ” active network, the old network can remain active but is no longer compatible with the new network. This effectively creates a new coin. Known hardforks are Bitcoin Cash (from →Bitcoin), and →Ethereum from (Ethereum Classic).

Hardware wallet: A hardware wallet is an electronic device that can create and store keys offline →Private . This method of storage is one of the most secure. Only using a →Paperwallets can be considered more secure. However, hardware wallets are much easier to use.

Therefore, unlike paper wallets, they can also be used in everyday life. Paper wallets are more suitable only for →cold storage. The two best known hardware wallets are the Trezor and the Ledger Nano S. There are also e.g. Keepkey and CoolWallet S.

Hash(rate): A hash function is a mathematical function which can be solved easily in one direction, but cannot (yet) be solved (analytically) in the other direction.

P2P: Peer 2/to Peer

Paper wallet: Denotes a piece of paper (or a piece of steel) on which the → Private key or the → Seed words that are needed to derive the private key are written. Paper wallets can be incredibly secure, but are very unsuitable for everyday use. Paper wallets are understood as → cold wallets.

PND: Pump and Dump

Ponzi scheme: A fraudulent system in which victims are encouraged to invest in an → ICO or company that does not conduct a legitimate business, but only by making a profit to find more and more lenders.

POS: Proof-of-Stake (POS)

POW: Proof-of-Work (POW)

Premine: A premine (pre-mining) takes place if a developer sends a certain number of coins to his own address before the blockchain is made public. Premine can be fraudulent, but it can also be seen as a means of paying for development and listing on exchanges.

Privacy (coin): Privacy coins usually use a → bitcoin-like ledger system, but add technology that obscures the path of the transaction. → Monero and ZCash are popular examples.

Private key: A private key is a character string, the possession of which is necessary to sign transactions and consequently to make transactions and thus send coins, for example. The owner of a private key owns the associated coins and can freely dispose of them.

If you lose your private key, you can no longer access your coins and orphan them. If you reveal your private key to another person, they now have full access to the coins in this address and can steal the coins.

Proof of stake: Proof-of-stake (POS) is a consensus algorithm in which the amount of coins you have is directly related to the probability that you can publish a block. Proof of Stake is very environmentally friendly compared to Proof of Work. There is no mining at Proof of Stake.

Proof of work: Proof of Work is a consensus algorithm to achieve global → consensus. This algorithm is used by → Bitcoin and other cryptocurrencies. With proof of work, → miners calculate various → hashes with high energy consumption.

Public key: A public key is a cryptographic key that can be shared publicly without any problems. Transactions are often sent to the public key. It is important never to confuse the private key with the public key. The public key can be thought of as the address of a mailbox for which the private key is the key to unlocking it.

Pump: With a pump, a few → Whales (a less liquid) coin ask very strongly in a short time, which results in an immense price increase.

Pump and dump: A → pump and → dump is a scam that requires a group of investors to buy a certain (less liquid coin) at the same time. As soon as uninitiated investors start to develop → FOMO and invest in the coin due to the price increase, all the initiated investors start selling off their previously purchased coins. This sale in turn leads to a drop in prices. The portfolio of uninitiated investors often lose a large amount of value in a very short time.
