This can be done in various ways, such as through email, SMS, entering a Google Authenticator code, or entering a code from a previously created list.


Annual percentage yield including reinvestment of income.

This is an economic concept whereby one party has a direct advantage in the efficiency of producing/providing a specific good or service compared to another party.

An investment strategy used by fund managers aiming to outperform the index or the market in order to generate profits.

A line of text indicating the location of a specific wallet in the blockchain. Often, it is a hashed version of the public key.

The distribution of tokens or shares that can be earned, purchased, or set aside for a particular investor, team, group, organization, or other affiliated party.

Structure that includes legal and regulatory procedures aimed at minimizing and restricting the flow of funds obtained from illegal or questionable activities. AML policy requires many exchanges or other crypto applications to "know their customers" (KYC). Customers are required to provide documentation to trade, withdraw funds, or use other features.

Application-Specific Integrated Circuit (ASIC) is a type of integrated circuit created to perform a specific task, such as "mining" Bitcoin. It consumes significantly less energy than graphics cards and has higher efficiency (mines coins faster). It is mainly used for industrial-scale mining.

Live event where assets or services are discussed and traded through a process often conducted by an auctioneer.

One of the goals of cryptography is to ensure that a message or transaction has been sent by the intended sender. Forms of cryptographic authentication include key authentication for public keys and source/user authentication for transaction authorization.

Assets under management (AUM) are the total market value of investments managed by an individual or entity on behalf of their clients.

ASIC miners are microchips or processors designed for specific tasks. ASICs for Bitcoin are very popular as they allow for more efficient mining, while mining on a regular computer loses efficiency. There are also specialized ASICs for faster mining of specific coins. Their use may become irrelevant if the protocol is updated, making the blockchain "ASIC-resistant."

The very first version of a product from developers. It typically has basic or limited functionality and requires improvements and bug fixes.

An archive node preserves all intermediate/transition/historical states of all blocks added to the blockchain. They may be used for research purposes.


The term used to indicate a situation when the market is moving downwards. The term also describes a person who is unsure about the future of a particular market (e.g. cryptocurrency market) and expects its value to decrease. This term can also be used to refer to a person who plans to profit from a downward movement by trading in a short position. Throughout the day, traders' sentiment may change from bullish to bearish, although they usually maintain a consistent position with respect to a particular asset.

A person who holds large amounts of cryptocurrency, or "wallets" in other words. Often used to describe someone who continues to hold their wallets even as the cryptocurrency's price decreases.

The initial purchase price for a trader or investor (including commission). Therefore, when the market price of the asset falls below the paid price, the trader needs to wait for a rise to exit and close the position without profit or loss. After achieving some take-profit targets, traders usually move their initial stop-loss to the breakeven point or beyond its values to make the trade successful.

A beta version is one of the early versions of a program or platform intended for user testing and feedback. The beta stage comes after the alpha stage. In the crypto space, a beta version is perceived positively because compared to many projects that cease to exist at the description stage, a beta version means the project has already started working. Many crypto projects are constantly changing and therefore require ongoing beta testing.

The bid price for an asset is the highest price that someone is willing to pay for that asset.

Bitcoin Dominance - the percentage of Bitcoin's market capitalization compared to the total cryptocurrency market capitalization. It is considered one of the key metrics.

A peer-to-peer, decentralized network that enables users to send units of value to each other without intermediaries or banks. A lesser-known fact is that the Bitcoin network also allows for data (such as text) to be stored on the blockchain.

The most popular story about a pizza that was purchased for 10,000 bitcoins on May 22, 2010. This was the first purchase of a physical item using bitcoins. May 22 is now recognized as "Bitcoin Pizza Day".

The positive price trend on the market. The term is widely used not only in the cryptocurrency space, but also in traditional markets.

Negative price dynamics of the market. The term is widely used not only in the cryptocurrency space but also in traditional markets.

Cryptocurrency created by a developer (or group of developers) under the pseudonym Satoshi Nakamoto. It was the first cryptocurrency, originally described as "a peer-to-peer electronic cash system" that operates using the "Proof-of-work" protocol by utilizing the computing power of nodes across the world.

Refers to the number of confirmations a specific block has. Each block preceding the block it refers to adds one block confirmation to it.

Bear trap is the opposite of a bull trap. In other words, it is a false downward trend. Traders may interpret this as a signal for a short position. However, the price rises, traders fall into the trap and lose money. A group of traders with large positions creates the bear trap. It can also arise on its own due to a deceptive pattern and crowd psychology.

This is a trading method that involves buying a coin that has just experienced a sharp drop, often due to FUD (fear, uncertainty, and doubt). However, sometimes these drops are natural and those who applied BTFD (buy the dip) may end up losing, and therefore are forced to launch a new wave of FOMO (fear of missing out) to quickly recover its price.

A period of unstable market growth due to irrational exuberance, which eventually "bursts" and leads to a market crash. One of the well-known bubbles is the dot-com bubble. Some consider the incredible surge in the cryptocurrency market in 2017 to be a bubble as well.

Bearish trend refers to a long-term decline in the market. The "long-term" decline lasts for at least a few months (for example, the bearish trend that began in mid-January 2018) and is represented by indicators such as moving averages with a negative shift (MA).

Bull trap is a false signal indicating that the price is about to rise, when in reality it is about to fall. As a result, bulls end up making bad trades. A typical example of a bull trap is a deceptive or fake breakout, a phenomenon where many people buy an asset thinking that it has broken through a resistance level, but later the "breakout" results in a candle with no follow-through.

A large order to buy at a specific price, which prevents orders at a lower price from being executed. Whales who manipulate the price of an asset or an individual buying a large sum may do this. Walls can create the impression that an asset is in demand and its price will not fall any further. However, buying walls can disappear as quickly as they appear.

The token standard for BSC (Binance Smart Chain).

A person who looks optimistically into the future of a particular market or asset (stocks, cryptocurrencies, bonds, etc.) can be referred to as a "bull."

The amount of coins awarded by a cryptocurrency blockchain protocol to miners for each successfully mined and verified block.

Decentralized digital network that records information about transactions and actions in chronological order using a chain of consecutive blocks.

A planned or accidental flaw in a cipher design that allows those who know about it to easily bypass the security mechanism is called a backdoor.

Baking is the process that Tezos uses to add new blocks of transactions to its blockchain. It is very similar to Delegated Proof of Stake. Bakers receive rewards for each "baked" block, similar to how Bitcoin miners receive rewards for opening new blocks. A baker is more likely to "bake" a block if they have large sums (at least 10,000 XTZ). To participate in baking, one must register a delegated account and can also bake on behalf of other users who do not meet the 10,000 XTZ requirement.

A person who believes that Bitcoin is the only cryptocurrency with real value or potential. One of the reasons, according to their opinion, is that there are already many software products and services accepting BTC as payment.

Bearish flag is a price chart pattern that resembles an inverted flag with a pole. It indicates that the market is likely to continue falling. The opposite of a "bullish flag".

A portfolio of coins and tokens that you intend to buy or hold. This term is often used to describe portfolios that are not very profitable but continue to be held because the current price is significantly lower than the entry price.

"Bear whale" is a person who holds large sums of cryptocurrency but has a "bearish" outlook. The bear whale takes any opportunity to sell a portion of their coins, which can hinder price growth or even lead to a decline.

Technical slang for "an error in design or implementation"; an unexpected flaw in a system. Fixing bugs is a common part of system development and interactive design.

"Bull flag" - a technical analysis pattern that indicates a possible continuation of an upward trend in the price chart. In form, the bull flag resembles a flag and pole. It is the opposite of a "bear flag."

The tendency for long-term growth in the market. Everyone defines a trend in their own way, but its duration is measured in months or years, not days or weeks. The trend is associated with indicators such as a positive slope in the moving average (MA).


The science of using mathematical theories and computations for encrypting and decrypting information is called cryptography.

In computer science, a shared pool of resources available to multiple users over the Internet.

Candlestick chart is a type of price chart that shows the highest, lowest, opening, and closing prices for a given period. It was invented by Japanese rice traders to track market prices and daily dynamics for hundreds of years before becoming popular in the United States. Each candlestick represents a period (day, hour, 15 minutes, etc.). The "body" of the candlestick represents the opening and closing price. The peaks (wicks) represent the highest and lowest prices over the time period.

A period of high sales when investors and traders liquidate their positions and sell off their assets as quickly as possible is called a "sell-off."

Central Bank Digital Currency (CBDC) is a digital fiat currency issued by central banks, as opposed to a cryptocurrency issued by a non-legislative entity.

A large system that includes one or more ciphers and usually entails much more, including key management, means to support secure boot, storage, use, reuse, archival, key loss, and key destruction. The system may also include means for secure key creation and encryption at the transport layer. Key storage may involve creating a mini-database with the actual key values selected by an open file alias (see: file alias). Key delivery may involve a complete public key component with its own construction, storage, use, loss, and key destruction requirements. This is especially true of some cryptographic key certification, and perhaps a large, complex, and expensive certification infrastructure.

Mining cryptocurrency using shared cloud computing power instead of one's own expensive and energy-consuming mining rig. Sometimes this method is associated with fraud, as it is difficult to prove the existence of certain operations and verify the principles of their operation.

A measure that reflects the number of blocks in the best block chain that would need to be altered to remove or change a specific transaction. A confirmed transaction has one or more confirmations.

The time from when a transaction is sent to the network to when it is recorded in a confirmed block. This time can vary significantly depending on the type of network and its conditions. Higher fees may serve as an incentive for miners to retrieve the transaction more quickly and thus reduce the waiting time. On the other hand, due to a minimum fee, the confirmation time can be significantly increased.

A new transaction in the blockchain must first receive confirmation before it is finally processed. This is done using one of the consensus mechanisms, such as proof of work and proof of stake. The more confirmations, the higher the probability that the transaction is valid and double-spending is no longer possible. Exchanges and applications have different requirements for the number of confirmations needed for a transaction to be considered final. The usability of cryptocurrencies is limited by the fact that confirmation times can vary. However, there are several solutions to this problem.

When a transaction is confirmed, it means that the network has approved it and it has been permanently added to the blockchain. Confirming a transaction takes some time. For example, on the Binance exchange, when depositing Bitcoins, the coins will be deposited after 1 network confirmation. Until 2 confirmations are received, the equivalent value of your assets will be temporarily unavailable for withdrawal.

Random number generator (RNG) used for cryptographic purposes. It is used to generate unpredictable sequences for stream ciphers.

Cryptanalysis is the analysis of information systems with the aim of studying their hidden aspects. It is used to break cryptographic security systems and gain access to the content of encrypted messages, even if the cryptographic key is unknown.

A mathematical mechanism that allows someone to prove ownership of a Bitcoin wallet and the Bitcoins stored in it.

A blockchain-based virtual game where players buy, collect, breed, and sell various breeds of virtual cats.

A cryptocurrency wallet that is offline in cold storage.

Wealth in the form of money or other assets owned by a person or organization. Sometimes capital is intended for purposes such as starting a company or investing.

A repeated operation in a sequence such that each result depends on the previous result or initial value. One example is block cipher mode. It is worth noting that a physical chain is not a good analogy for describing multiple encryption because a physical "chain" is only as strong as its weakest link, whereas a sequence of encryption is only as strong as its strongest link.

Ciphertext is text that has been made unreadable, making the information contained in it secret. Ciphertext is the result of encryption and is the opposite of plaintext. Usually, the encrypted text will appear random, with values in the ciphertext being balanced.

"Close" is a financial term that refers to the closing price and signifies the final price at which an asset was sold at the end of a particular period of time. Monitoring closing levels on a chart allows for making trading decisions. This also applies to the cryptocurrency market, but on smaller timeframes. It will be more difficult to predict where the closing will be on the cryptocurrency market chart, as this market is characterized by rapid price changes and the crowd psychology effect.

Pledging something valuable as collateral for the repayment of a loan. Nowadays, many services accept cryptocurrencies as collateral for obtaining loans online, and sometimes offline.

A basic wallet that contains a full copy of the blockchain, allowing users not only to receive, store, and send digital assets, but also to issue commands through the interface and program the blockchain.

A temporary interruption in an upward trend, but then a return to the upward trend. Correction and the formation of support lines are normal features of an upward trend. A rapidly rising market without any pullbacks can crash down as quickly as it went up.

A statistical relationship, not necessarily linear, usually between two variables. Traders and market analysts study correlations between asset classes and various pairs. For example, most cryptocurrencies are typically correlated with the price of Bitcoin.

A way of raising funds where many people contribute small amounts. By receiving 20 dollars from 1000 people, the company can quickly and easily raise 20,000 dollars.

Assets that utilize cryptography, agreed-upon algorithms, distributed ledgers, peer-to-peer technologies, and/or smart contracts, and serve as a store of value, medium of exchange, unit of account, or decentralized applications.

A bubble occurs when the price of an asset exceeds its intrinsic value and rapidly rises for a prolonged period of time without corrections or support. Few understand cryptocurrencies, so some consider it a "bubble." Some consider the rise of cryptocurrencies in 2017 to be a bubble that then burst, after which prices fell for a prolonged period of time.

The term that describes the overall process of encryption is "cryptosystem". It is a set of cryptographic algorithms that are implemented to achieve a specific security function, most commonly confidentiality (encryption). Typically, a cryptosystem includes three algorithms: one for key generation, one for encryption, and one for decryption.

A symmetric key algorithm for encrypting digital data. The algorithm has had a strong influence on the development of cryptography, although the short key length of 56 bits makes it insecure for use in modern applications.

The amount of money a company (usually on an annual basis) pays out to its shareholders from its profits (or reserves). Dividends are also inherent to some tokens that offer regular payouts to their owners. These payments may be a part of the platform's revenue or fees.

The block size refers to the amount of space that a cryptocurrency can store in each block. For example, currently, each block in the Bitcoin blockchain can hold 1 MB of data, meaning that the size of a Bitcoin block is 1 megabyte. This places a limit on the number of transactions that can fit into Bitcoin blocks, based on the data contained in the specified transactions.

Day trading. Day traders make multiple trades throughout the day and profit from small market fluctuations. The opposite of swing trading, where traders take longer positions.

A small price increase after a significant decline, giving false hope of further growth.

This is the process of earning tokens as a reward for providing liquidity to a project by depositing a certain token pair into a pool.


Making a profit when the price of an asset falls. There are several ways to short an asset: buying put options, borrowing the asset from a broker, immediately selling it, and then buying back the same amount of the asset - possibly at a lower price - to repay the broker's debt. A less risky way to pseudo-short a cryptocurrency is to sell a certain amount of your own cryptocurrency holdings, expecting the price to drop, and then buy back the same amount at a lower price.

The very first block in the blockchain - a decentralized blockchain system.

A little-known cryptocurrency with significant, if not gigantic, potential. By investing in it, traders expect a multiple increase in its value, or, as they say, "big X's".

Bullish chart pattern where a short-term moving average crosses above a longer-term moving average.

The purchase of an asset with the intention of selling it at a higher price. This does not necessarily mean that you will hold the position for an extended period of time. For example, day traders "go long" when they buy stocks and then sell them at a higher price within hours. Going long also indicates a bullish sentiment towards a particular asset or currency.


In the cryptocurrency space, the term "halving" refers to the process that reduces the rate at which new coins are issued. More specifically, halving is a periodic reduction in the reward for a block provided to miners.

The term "hash rate" refers to the speed at which a computer can perform hashing calculations. In the context of Bitcoin and cryptocurrencies, hash rate represents the efficiency and performance of a mining machine, determining how quickly the mining hardware can work to calculate a valid block hash.

The type of fork where the rules of the blockchain are changed in such a way that transactions of the previous version are no longer valid in it. It requires software updates by all participants in the chain.

The maximum amount of funds that a project aims to raise during its fundraising campaign (ICO/IEO/STO).

A type of cold storage. It is an external technology similar to a memory card that stores private keys. They are immune to viruses and often have buttons to confirm transactions, so the funds are only accessible if the password is known and the device is physically available.

This is also called hash rate; it is a term used to measure the overall computing power in a blockchain network for continuous operation.

Online storage of private keys that provides faster access to cryptocurrencies, but is more vulnerable to attacks and other forms of fraud. The opposite of cold storage.

Allows for the use of both Proof-of-Stake and Proof-of-Work as distributed consensus algorithms. This approach combines the security and consensus management of PoW, and the energy efficiency and community involvement of PoS.

A hash function collision is when two different input data blocks x and y for the hash function H result in H(x) = H(y). Collisions exist for most hash functions, but for "good" hash functions, their frequency of occurrence is close to the theoretical minimum.

The issuance by a project or company of a cryptocurrency intended to be used as payment for goods and services offered by that project or company in the future.

An increase in the overall price level, caused by an overflow of the channels of circulation of the money supply beyond the needs of trade, leading to a devaluation of the monetary unit and rising prices.

A fundraising event that is conducted and controlled by a centralized exchange, such as Launchpad on Binance.

A request to buy or sell a large amount of an asset, split into multiple contracts to hide the total order size. Such orders are common on traditional exchanges and are rarely used on crypto exchanges.

Increasing the amount of borrowed assets to multiply profits. Increasing leverage is considered risky. If the price starts moving in the opposite direction of the desired outcome (even shortly before a reversal), it can lead to significant losses or even liquidation.

Financial instrument for tracking the price of an asset.


Jager in cryptography may refer to the smallest unit of Binance Coin (BNB). Most cryptocurrencies are divisible to decimal places as specified in each cryptocurrency protocol. This type of unit often receives its own name. For example, in Bitcoin, it is called Satoshi.
