2FA (two factor authentication)

Metaverse Crypto Dictionary

Two-Factor Authentication (2FA) is a security method that requires two separate layers of security to verify a user’s identity. Typically, it involves a combination of something the user has (such as a code received via an app on their phone or through SMS) and something the user knows (like a password).

This system provides an extra layer of security compared to traditional single-factor authentication methods (like just a password).

If an attacker manages to obtain one factor (like the password), they still need the second factor to gain access, making unauthorized access significantly more difficult. 2FA is commonly used in online banking, email services, and social media platforms to enhance security

51% Attack

Metaverse Crypto Dictionary

A 51% attack refers to a situation in the blockchain network, particularly in cryptocurrencies, where a single entity or group gains control of more than 50% of the network’s mining power, hash rate, or computing power.

This majority control allows them to manipulate the blockchain in several ways. They can prevent new transactions from gaining confirmations, allowing them to halt payments between some or all users. They could also reverse transactions that were completed while they controlled the network, leading to a double-spending problem.

However, achieving such a level of control is exceptionally difficult and costly, especially on larger networks like Bitcoin. It’s more feasible on smaller, less established networks.

Crypto Addresses

A crypto address is a unique identifier used in cryptocurrency transactions. It functions similarly to a bank account number, allowing users to send and receive digital currency like Bitcoin, Ethereum, or other cryptocurrencies. Each address is a long string of letters and numbers, typically generated from the user’s cryptographic public key.

It’s important to note that each cryptocurrency operates on its own address format, so an address for Bitcoin, for example, won’t work for Ethereum transactions.

Users must ensure they use the correct address type for the specific cryptocurrency they’re dealing with to avoid losing funds. These addresses can be shared publicly to receive funds, but they don’t reveal the identity of the owner, maintaining a level of anonymity in transactions.


An airdrop in the context of cryptocurrency is a distribution method where free tokens or coins are sent to multiple wallet addresses.

This is often done by blockchain projects to promote a new virtual currency, increase its circulation, and encourage its adoption by the public. Airdrops can be distributed to holders of a particular existing cryptocurrency, like Bitcoin or Ethereum, or to users who have signed up or performed a specific task like joining a community, promoting the project on social media, or holding a certain amount of the token already.

Airdrops are seen as a marketing strategy to gain attention in the crowded cryptocurrency space and to reward early supporters of a project. However, recipients should be cautious, as sometimes airdrops can be associated with scams or fraudulent schemes.

Algorithmic Trading

Algorithmic trading refers to the use of computer algorithms to execute trading orders with minimal human intervention. This method relies on complex mathematical models and formulas to make high-speed, automated decisions for buying or selling financial instruments.

Algorithmic trading strategies can range from simple automation of order execution to sophisticated trading tactics based on quantitative models.

This approach enables traders to process large volumes of transactions at high speeds, often capitalizing on small price fluctuations in the market.

It’s commonly used by institutional investors and large trading firms, especially in markets such as stocks, forex, and cryptocurrencies. Algorithmic trading can improve market efficiency, but it also raises concerns like market volatility spikes and systemic risks due to interconnected automated systems.


Crypto accumulation refers to the strategy of systematically buying and holding a cryptocurrency over a period, especially during price dips or bear markets. This approach is based on the belief that the cryptocurrency’s value will increase significantly over the long term.

Accumulation is often practiced by investors who have a strong conviction in the underlying technology or potential of a particular cryptocurrency. They use periods when the asset’s price is lower to increase their holdings, aiming to benefit from future price appreciation.

This strategy contrasts with active trading, focusing instead on long-term investment and often involves ignoring short-term market fluctuations.


An “altcoin” is a term used in the cryptocurrency world to refer to any digital currency other than Bitcoin. The word “altcoin” combines “alternative” and “coin,” implying that these cryptocurrencies are alternatives to Bitcoin.

Altcoins may vary widely in their functionality, underlying technology, and intended use cases. Some altcoins, like Ethereum, offer different technological platforms and are used for smart contracts and decentralized applications, while others might have specific features like enhanced privacy, lower transaction costs, or different consensus mechanisms (like proof of stake instead of proof of work). The altcoin market is vast and diverse, with new altcoins emerging regularly.


Crypto arbitrage is a trading strategy that takes advantage of price differences of a cryptocurrency across different exchanges. Essentially, it involves buying a digital asset where the price is lower and then selling it on another exchange where the price is higher. This practice is common due to the fragmentation of cryptocurrency markets where supply and demand can vary significantly from one exchange to another, leading to price disparities.

Arbitrage opportunities can emerge rapidly and are often short-lived, as the act of arbitraging tends to close the price gaps. Traders use automated systems and algorithms to identify and execute these trades quickly. Crypto arbitrage is seen as a relatively low-risk way to make a profit but requires a good understanding of market dynamics and often a significant amount of capital to be effective.

ATH(All Time High)

“ATH” in the context of cryptocurrency stands for “All-Time High.” This term refers to the highest price that a particular cryptocurrency has ever reached since its inception. Tracking the ATH of a cryptocurrency can provide insight into its historical performance and market sentiment.

For investors and traders, the ATH is a significant metric, as it represents the peak value of the asset. Breaking past an ATH can be a bullish indicator, while failure to reach or surpass an ATH during a market uptrend might suggest resistance or a lack of momentum. It’s important to note that the ATH is a historical marker and does not necessarily indicate future performance.

ATL(All Time Low)

“ATL” in cryptocurrency stands for “All-Time Low.” This term is used to describe the lowest price point that a cryptocurrency has ever reached since its introduction to the market. Monitoring the ATL provides insight into the historical valuation and potential bottom price levels of a cryptocurrency.

For investors and traders, the ATL is a critical metric, reflecting the lowest valuation of the asset. It can be a point of interest for buying opportunities, under the belief that the price might increase from this lowest point.

However, it’s important to approach ATL with caution, as it doesn’t guarantee future price increases and may reflect underlying issues with the cryptocurrency or market conditions.


In the volatile landscape of cryptocurrency investing, the term ‘bagholder’ has emerged as a colloquial, yet poignant descriptor for investors who hold onto their assets through thick and thin, often to their detriment. This comprehensive article aims to explore the concept of a crypto bagholder, understanding its implications, strategies to avoid becoming one, and how to manage if you find yourself in this situation.


“Crypto bearish” refers to a period or trend in the cryptocurrency market that is characterized by a downward trajectory. This term is commonly used to describe times when prices are falling, investor confidence is diminishing, and there is increased selling pressure.

“Bearish” is a term used in financial markets to denote a general downtrend and is synonymous with a “bear market.” In the context of cryptocurrencies, bearish periods are often characterized by declining market values due to uncertainty, pessimistic outlooks, or negative news. During these times, investors may tend to sell off their assets to avoid value loss.


“Crypto bullish” refers to a period or trend in the cryptocurrency market that is characterized by an upward trajectory. This term is commonly used to describe times when prices are rising, investor confidence is increasing, and there is a strong buying pressure.

“Bullish” is a term used in financial markets to denote a general uptrend and is synonymous with a “bull market.” In the context of cryptocurrencies, bullish periods are often characterized by positive outlooks, good news, or a general optimism in the market leading to an increase in market values. During these times, investors may tend to buy assets to benefit from the value appreciation.


A “crypto block” refers to a fundamental unit in blockchain technology, which is the underlying structure for most cryptocurrencies. Each block contains a collection of transactions that have been verified and added to the blockchain.

Every block has a unique code known as a “hash,” which distinguishes it from other blocks. Additionally, each block contains the hash of the previous block, creating a linked chain of blocks – hence the term “blockchain.” This chaining ensures the security and integrity of the transaction history, as altering any information in a block would require changing every subsequent block, which is computationally impractical.

Blocks are created through a process called “mining” in many cryptocurrencies, where miners use powerful computers to solve complex mathematical puzzles.


Blockchain is a digital ledger technology that stores data in a chain of blocks. Each block contains a number of transactions, and every new transaction is recorded across each copy of the ledger in the network, providing high transparency and security.

The data in a blockchain is decentralized, meaning it is not stored in a single location but is distributed across multiple nodes (computers) in the network, making it highly resistant to tampering and cyber attacks.

One of the key features of blockchain is that once data is added to a block and the block is linked to the chain, it becomes very difficult to alter. This is because each block contains its own hash (a unique digital fingerprint) and the hash of the previous block. Changing any information would require altering all subsequent blocks, which is computationally infeasible in a large network.

Circulating Supply

Circulating Supply refers to the total number of a cryptocurrency’s coins or tokens that are publicly available and circulating in the market. This metric is crucial for understanding the current supply of a cryptocurrency that is actively being traded, used, and held by the public. It excludes coins or tokens that are locked, reserved, or not yet released into the market.

The circulating supply is different from the total supply, which includes all coins or tokens that have been mined or created, regardless of their status.

The circulating supply is often used to calculate the market capitalization of a cryptocurrency, which is done by multiplying the circulating supply by the current price per coin or token. This measure helps investors and analysts gauge the relative size and value of different cryptocurrencies.

Crypto coin

A “crypto coin” is a type of digital or virtual currency that uses cryptography for secure financial transactions, control of the creation of additional units, and the verification of the transfer of assets. Coins are native to their own independent blockchain, where they serve as a medium of exchange, a store of value, or a unit of account.

Unlike tokens, which are built on existing blockchains, coins have their own blockchain. Prominent examples include Bitcoin, Ethereum, and Litecoin, each operating on its own distinct blockchain.

These coins can be used for a variety of purposes, including investment, purchases, and transfers, embodying the decentralized nature of blockchain technology.

Coin burn

Coin burn in cryptocurrency refers to the process of permanently removing coins from circulation, effectively reducing the total supply.

This is achieved by sending a portion of the coins to a wallet that has no accessible private key. Since no one can access these coins, they are considered permanently out of circulation. Coin burning is often used as a mechanism to control inflation, increase the scarcity of the coins, or improve the coin’s economics.

By reducing the supply, the theory is that the value of the remaining coins may increase if demand remains constant or increases. This technique is used by various cryptocurrency projects as part of their tokenomics (token economics) strategy.

Cold Storage

Crypto cold storage refers to keeping a reserve of cryptocurrency offline, away from the reach of online hackers. This method is considered one of the safest ways to store cryptocurrencies, as it reduces the risks associated with internet-based threats like hacking, phishing, and other forms of cyber-attacks.

Cold storage can be achieved through various means such as hardware wallets, paper wallets, or even storing the private keys in a secure physical location like a safe. Unlike hot wallets, which are connected to the internet and more convenient for frequent trading and transactions, cold storage is primarily used for long-term holding, where security is prioritized over accessibility.

By keeping the crypto assets offline, cold storage ensures a high level of protection against unauthorized digital access.

Cold Wallet

A crypto cold wallet, also known as a cold storage wallet, refers to a method of storing cryptocurrency offline to protect it from online hacking risks. Unlike hot wallets, which are connected to the internet and more susceptible to cyber attacks, cold wallets are not connected to the internet, significantly enhancing their security.

Cold wallets can come in various forms, such as hardware wallets (physical devices like USB drives designed to store private keys securely), paper wallets (printed pieces of paper containing the private and public keys), and even steel wallets (engraved pieces of metal with private key information).

These wallets are ideal for long-term storage of cryptocurrencies, as they minimize the risk of theft from online breaches. However, they are less convenient for frequent transactions compared to hot wallets.


Crypto consensus refers to the mechanism used by a blockchain network to achieve agreement on the state of the ledger, ensuring that all participants in the decentralized network have the same data. In a blockchain, consensus algorithms are crucial because they provide a way to achieve reliability and security in a distributed environment, where there is no central authority.

There are several types of consensus mechanisms, with the most common being Proof of Work (PoW) and Proof of Stake (PoS). Proof of Work, used by Bitcoin, involves solving complex mathematical puzzles to validate transactions and create new blocks. Proof of Stake, on the other hand, selects validators in proportion to their quantity of holdings in the cryptocurrency. This approach is less energy-intensive compared to PoW.

These consensus mechanisms are fundamental to the operation of blockchain networks, ensuring that all transactions are valid, preventing double-spending, and maintaining the integrity and security of the ledger.


A DAO, or Decentralized Autonomous Organization, is an organizational structure built and run through blockchain technology, primarily using smart contracts.

These smart contracts are self-executing contracts with the terms of the agreement directly written into code. DAOs operate without centralized control, meaning there is no single authority like a CEO or board of directors.

The key feature of a DAO is that it’s governed by its members, who typically hold tokens in the organization. These tokens grant voting rights, allowing members to collectively make decisions about the future of the organization, such as managing resources or deciding on project directions.

DAOs aim to democratize decision-making and automate administrative functions, leveraging the transparency and security of blockchain technology.


In the context of cryptocurrency, “decentralized” refers to the distribution of power and control away from a central authority.

This concept is a key feature of many blockchain technologies and cryptocurrencies. In a decentralized system, the control and decision-making are spread across a network of multiple nodes (computers), participants, or stakeholders, rather than being concentrated in a single entity like a government, organization, or individual.

Decentralization offers several advantages, such as increased security (as there is no single point of failure), transparency (since all transactions are publicly recorded on the blockchain), and resistance to censorship or control by any single authority.

This is in stark contrast to traditional centralized systems, where a central authority has significant control over the system’s operation and management. Cryptocurrencies like Bitcoin are prime examples of decentralized systems, where transactions and the issuance of new units are managed collectively by the network

DAPP (decentralized application)

A Decentralized Application (DApp) is a software application that runs on a distributed computing system, most commonly a blockchain. Unlike traditional applications, which run on centralized servers, DApps operate on a decentralized network, supported by a blockchain’s infrastructure.

DApps are built on smart contract technology, which allows them to operate autonomously without the need for a central authority to manage transactions or data. This ensures that DApps are resistant to censorship, downtime, and interference from a central entity.

These applications are often open source, meaning their code is available for review and contributions by anyone. They typically use cryptocurrency tokens to handle transactions and incentivize network participants.

DApps can be developed for a wide range of uses, including finance, gaming, social media, and more, leveraging the security, transparency, and decentralization offered by blockchain technology.

Distributed Ledger

A Distributed Ledger is a type of database that is spread across multiple sites, countries, or institutions. Unlike traditional databases, which are centralized, distributed ledgers have no central data store or administration functionality. In a distributed ledger, each node (participant in the network) holds a copy of the ledger and updates itself independently.

The most well-known application of distributed ledger technology (DLT) is blockchain, which underpins various cryptocurrencies. These ledgers are immutable, meaning once a transaction is recorded, it cannot be altered. This feature adds a layer of security and transparency, as all transactions are recorded and verified by consensus among participants in the network.

Distributed ledgers are used not only for cryptocurrencies but also for other applications like supply chain management, voting systems, and digital identities, offering a secure and transparent way to record transactions and track assets in a decentralized manner.


Ether (ETH) is the native cryptocurrency of the Ethereum blockchain, which is a decentralized platform that enables the creation and execution of smart contracts and decentralized applications (DApps). Ether serves two main purposes: it is traded as a digital currency on various cryptocurrency exchanges like other digital currencies, and it is used within the Ethereum platform to run applications and compensate participants for computations performed.

Ether acts as the “fuel” for operating the Ethereum network. It’s used to pay for transaction fees and computational services on the Ethereum network. When users interact with a DApp, send ETH, or execute smart contracts on Ethereum, they must pay a fee in Ether to compensate for the computing energy required for these operations. This fee is called “gas,” and its price varies based on network demand. Ether’s versatility as both a digital currency and a utility token for running Ethereum’s smart contracts is a key aspect of its design and appeal.

Fiat money

Cryptocurrency is a digital asset that operates in a decentralized manner, typically using blockchain technology.

Bitcoin is one of the most famous examples of cryptocurrency. Cryptocurrencies secure transaction records using blockchain and do not require a central authority, such as a central bank. Consequently, cryptocurrencies can be directly transferred between users and operate outside the control of central governments or financial institutions.


A crypto fork is a fundamental change or divergence in the underlying protocol or rules of a blockchain network, resulting in two separate and distinct chains. This can happen for various reasons, such as software updates, disagreements among network participants, or changes in the consensus mechanism.


FOMO is short for Fear of Missing Out. It refers to the anxious state of someone who is experiencing an event right now and feels as though he or she is missing the opportunity.

For example, the position does not hold while Bitcoin increases and the value of the position continues to increase while it does not. As a result, he got caught in the FOMO and opened a position.


FUD stands for “Fear, Uncertainty, and Doubt.” It is a term commonly used in the cryptocurrency and financial markets to describe the spread of negative or misleading information about a particular cryptocurrency, project, or market in order to create fear and uncertainty among investors or participants. The goal of spreading FUD is often to manipulate prices or to discredit a project or technology.

In essence, FUD is a tactic employed by some individuals or groups to instill doubt and anxiety in others, causing them to make rash decisions like selling their holdings or avoiding certain investments. It’s essential for investors to conduct thorough research and critical analysis to differentiate between genuine concerns and baseless FUD in the crypto space.


A “FUDster” is a term used in the cryptocurrency and financial markets to refer to individuals or entities who actively spread FUD (Fear, Uncertainty, and Doubt) about a particular cryptocurrency, project, or market.

FUDsters intentionally disseminate negative or misleading information with the aim of creating fear and uncertainty among investors or participants, often to manipulate prices or discredit a project or technology.

They engage in such behavior for personal gain or to influence market sentiment. FUDsters are generally not interested in providing accurate information but rather in creating panic or doubt to achieve their objectives.


In the context of cryptocurrencies, “gas” refers to a unit of measurement for the computational work required to perform actions or transactions on a blockchain network, particularly on platforms like Ethereum.

It represents the fee that users need to pay in order to execute smart contracts, send tokens, or perform other operations on the blockchain.

Gas is used to ensure the proper functioning of the network and to prevent abuse by requiring users to allocate a certain amount of cryptocurrency (usually Ether in the case of Ethereum) to cover the computational resources required for their transactions.

The higher the complexity or demand on the network, the more gas is needed, and the higher the associated transaction fee will be.

Gas Limit

In the context of cryptocurrencies like Ethereum, the “Gas Limit” is a parameter that specifies the maximum amount of computational work or operations that a user is willing to pay for in a single transaction or smart contract execution. It is expressed in terms of units called “gas.”

When a user initiates a transaction or executes a smart contract on the Ethereum network, the Gas Limit determines the upper limit for the computational resources (gas) that can be consumed during that operation. If the actual gas consumption exceeds the specified Gas Limit, the transaction or operation will fail, but the user will still be charged for the gas used up to that point.

Setting an appropriate Gas Limit is crucial because it ensures that complex transactions or smart contracts can execute successfully without running out of computational resources. However, setting it too high may result in unnecessarily high transaction fees, as users are charged based on the gas consumed.

In summary, the Gas Limit in cryptocurrencies like Ethereum is the maximum amount of computational work a user is willing to pay for in a single transaction or smart contract execution, and it plays a crucial role in managing transaction fees and ensuring successful operations.

Gas Price

In the context of cryptocurrencies like Ethereum, “Gas Price” refers to the amount of cryptocurrency (typically in Ether) that a user is willing to pay for each unit of computational work or gas required to execute a transaction or smart contract on the blockchain network. Gas Price is a critical factor in determining the cost of a transaction.

Users can specify the Gas Price they are willing to pay when submitting a transaction. A higher Gas Price means that the transaction is more likely to be processed quickly, as miners and validators are incentivized to prioritize transactions with higher fees. Conversely, a lower Gas Price may result in slower transaction processing times, as miners may prioritize transactions with higher fees.


“Gwei,” short for “gigawei,” is a unit of measurement for the Gas Price in cryptocurrencies like Ethereum. It represents a tiny fraction of one Ether (ETH), which is the native cryptocurrency of the Ethereum blockchain. Gwei is used to express the cost of computational work or transaction fees on the Ethereum network in a more user-friendly and manageable manner.

Since Ether (ETH) can have a high value, expressing transaction fees in terms of Gwei makes it easier for users to understand and work with smaller denominations when setting Gas Prices for their transactions. For example, a Gas Price of 20 Gwei means that a user is willing to pay 20 billionths of one Ether for each unit of computational work or gas required for a transaction.


“Halving” in the context of cryptocurrencies, especially Bitcoin, refers to a pre-programmed and periodic reduction in the rewards that miners receive for validating and adding new blocks to the blockchain. It’s called “halving” because the rewards are cut in half.

In the case of Bitcoin, which experiences a halving approximately every four years, the initial block reward for miners was 50 Bitcoins when the network started. After the first halving event, it was reduced to 25 Bitcoins, then to 12.5 Bitcoins, and so on. The next halving would reduce it to 6.25 Bitcoins, and this process continues.

Hard Cap

Cryptocurrency “Hard Cap” refers to the maximum supply or limit of a specific cryptocurrency that will ever be created. It represents the highest quantity of coins or tokens that can exist within a particular blockchain or crypto project. Once the hard cap is reached, no more units of that cryptocurrency will be generated, making it a finite and limited digital asset.

For example, Bitcoin has a hard cap of 21 million coins, which means that only 21 million Bitcoins will ever be mined. This scarcity is often seen as a feature that can influence the cryptocurrency’s value and adoption, as it contrasts with traditional fiat currencies that can be printed in unlimited quantities by central authorities.

Hard Fork

A hard fork is a major alteration to a blockchain’s rules and protocol, leading to the emergence of two distinct and incompatible blockchains.

This typically occurs due to disagreements or changes in the network’s consensus mechanism, and it can result in the formation of a new cryptocurrency. Participants must usually update their software to continue using the network after a hard fork.

Hash Function

A cryptographic hash function is a mathematical process that converts any form of data into a fixed-size string of bytes, creating a unique “fingerprint” for the data. This function is deterministic, meaning the same input always results in the same output.

It’s designed to be fast, yet secure against reverse-engineering (pre-image resistance) and producing the same output for different inputs (collision resistance). It’s widely used in various security applications and for integrity verification.


Hashrate in cryptocurrency refers to the speed at which a computer is completing an operation in the cryptocurrency’s code. In other words, it measures the computational power being used to mine and process transactions on a blockchain.

A higher hashrate means greater mining power and efficiency, increasing the chances of solving the cryptographic puzzles and earning cryptocurrency as a reward. It’s typically measured in hashes per second (h/s).

HFT (Higher Frequency Trading)

High-Frequency Trading (HFT) in cryptocurrency is a trading method that uses powerful computers to execute a large number of orders at extremely high speeds.

These systems utilize complex algorithms to analyze market conditions and execute trades based on market conditions within fractions of a second. HFT can be used to capitalize on very small price differences, and it’s known for its efficiency and high trading volume. In the crypto markets, HFT can significantly impact price discovery and market liquidity.


“HODL” in cryptocurrency is a term derived from a misspelling of “hold,” used by the crypto community to refer to a strategy of holding onto cryptocurrency rather than selling it, even in the face of market fluctuations.

It represents a long-term investment philosophy where investors believe in the future value of a cryptocurrency, regardless of short-term market trends or volatility. The term gained popularity and cultural significance within the crypto community, symbolizing a belief in the enduring value of cryptocurrencies.

Hot Storage

Hot storage in cryptocurrency refers to a method of storing digital assets, like cryptocurrencies, in wallets that are connected to the internet. This type of storage is convenient for frequent access and transactions, as it allows users to send and receive cryptocurrencies with ease.

However, because they are online, hot wallets are more susceptible to hacking, cyber-attacks, and other online vulnerabilities compared to cold storage solutions, which are offline. Examples of hot storage include software wallets, mobile wallets, and online exchange accounts.

Hot Wallet

A hot wallet in cryptocurrency is a digital wallet that is connected to the internet. It allows for easy and quick transactions, making it convenient for regular use in trading and spending digital currencies.

However, being online, hot wallets are more vulnerable to security risks like hacking and cyber attacks. They are typically used for holding smaller amounts of cryptocurrency that a user might need for daily transactions, as opposed to cold wallets, which are used for safer long-term storage. Examples include mobile and desktop wallets, as well as wallets provided by online crypto exchanges.

KYC (Know Your Customer)

KYC, or “Know Your Customer,” in the context of cryptocurrency, is a compliance process used by businesses, especially exchanges and wallet providers, to verify the identity of their clients. This process is part of anti-money laundering (AML) measures.

KYC involves collecting and verifying personal information like name, address, and government-issued IDs. It’s intended to prevent fraud, money laundering, and terrorist financing by ensuring that businesses are not used for illicit activities.

While KYC can enhance security, it also raises concerns about privacy and the decentralized nature of cryptocurrencies.


In cryptocurrency, a ledger is a digital record-keeping system that tracks all transactions of a particular cryptocurrency. It’s decentralized and distributed across a network of computers, known as nodes. This ledger is updated and maintained through a consensus mechanism, ensuring that each copy of the ledger is identical and accurate.

The most well-known form of a cryptocurrency ledger is the blockchain, which records transactions in blocks linked together in a chronological order, providing transparency and security against fraud and tampering. This decentralized nature makes the ledger a key component of the trust and security in cryptocurrencies.

Market Capitalization (Market Cap)

Market capitalization, often shortened to market cap, is a measure used to determine the total market value of a company or asset.

In the context of stocks, it’s calculated by multiplying the total number of a company’s outstanding shares by the current market price of one share. For cryptocurrencies, market cap is determined by multiplying the current price of the cryptocurrency by its total circulating supply.

Market cap is a critical metric used by investors to gauge the size and growth potential of a company or the relative size of a cryptocurrency in the market, providing a quick and straightforward way to compare the value of different assets.

Max Supply

Max Supply in the context of cryptocurrency refers to the maximum number of coins or tokens that will ever exist for a given cryptocurrency. This is a fixed limit set by the cryptocurrency’s protocol and cannot be changed.

It’s a crucial part of a coin’s economic model, influencing its scarcity and potential value. For example, Bitcoin has a max supply of 21 million coins, meaning no more than 21 million bitcoins will ever be mined. The concept of max supply is important for investors and users as it helps in understanding the potential supply-related constraints on a cryptocurrency’s value over time.


MetaMask is a popular cryptocurrency wallet and gateway to blockchain-based applications, commonly used for interacting with the Ethereum blockchain.

It allows users to store and manage account keys, broadcast transactions, send and receive Ethereum-based cryptocurrencies and tokens, and securely connect to decentralized applications (dApps) through a compatible web browser or mobile app.

MetaMask functions both as a wallet and a browser extension, providing a user-friendly interface to access the Ethereum ecosystem, including its many smart contracts and decentralized applications. It plays a key role in facilitating access to the decentralized web, often referred to as Web3.


A “crypto miner” refers to an individual or device that solves complex mathematical problems to earn blockchain-based cryptocurrencies (like Bitcoin, Ethereum, etc.). This process maintains the security of the cryptocurrency network and verifies its transactions.

Miners create new blocks by solving these problems and are rewarded with units of the cryptocurrency. This activity typically requires significant computational power and can consume a lot of energy. Crypto mining plays a crucial role in maintaining the decentralized nature of the blockchain, ensuring that transactions are securely and transparently recorded.


Crypto mining is the process of using computer hardware to perform complex calculations for a blockchain network in exchange for rewards in the form of cryptocurrency. It involves validating data blocks and adding transaction records to a public ledger known as a blockchain.

This is essential for maintaining the integrity and security of the blockchain. Miners compete to solve mathematical puzzles, and the first to solve it gets the right to add a new block to the blockchain and is rewarded with cryptocurrency. This process requires significant computational power and electricity, making it both resource-intensive and competitive.


“Crypto mooning” is a slang term used in the cryptocurrency community to describe a situation where the price of a cryptocurrency is experiencing a very sharp, rapid increase. The term is derived from the phrase “going to the moon,” implying that the value of the cryptocurrency is soaring high like a rocket.

This term is often used in informal discussions among traders and investors when a cryptocurrency sees significant gains in a short period, leading to excitement and speculation about its future value. It’s important to note that such rapid increases can be volatile and speculative in nature.

On chain

“Crypto on-chain” refers to transactions and activities that occur directly on the blockchain and are recorded on the network’s public ledger. This includes cryptocurrency transfers, smart contract executions, and any other actions that are processed and validated by the blockchain.

On-chain activities are immutable, meaning once they are recorded on the blockchain, they cannot be altered or deleted. This ensures transparency and security, as all transactions are publicly visible and verified by the network’s participants. On-chain operations contrast with “off-chain” activities, which occur outside of the blockchain network and are not recorded on the public ledger.


“Crypto P2P” refers to peer-to-peer transactions in the context of cryptocurrencies. It means the direct exchange of digital assets, like Bitcoin or Ethereum, between individuals without the involvement of a central authority or intermediary, like a bank or a traditional financial institution.

These transactions are facilitated by blockchain technology, which ensures security and transparency. P2P crypto exchanges allow users to trade cryptocurrencies directly with one another, often using a decentralized platform or application. This approach to trading is valued for its privacy, reduced transaction fees, and increased control over the trade process.


A “parachain” in the context of cryptocurrency refers to a type of blockchain that operates in parallel to a main chain or “relay chain.” Parachains are individual blockchains that connect to and run alongside a central blockchain, enabling multiple chains to work in tandem and share the main chain’s security and processing power.

This concept is integral to some blockchain networks like Polkadot, where parachains can have their own tokens, governance rules, and specific functionalities but benefit from the security and interoperability provided by the main chain. Parachains are designed to increase scalability and efficiency, allowing for specialized, optimized blockchains that can communicate and interact with each other within a larger ecosystem.

PoS (Proof of Stake)

Proof of Stake (PoS) is a consensus mechanism used in some cryptocurrencies as an alternative to Proof of Work (PoW). In PoS, the right to validate or mine new blocks is determined by how many coins a user holds.

This means that the more cryptocurrency a miner owns, the more mining power they have. Unlike PoW, which requires significant computational power to mine coins, PoS relies on the stake or ownership of coins to secure the network.

This method reduces the amount of computational work needed, making it more energy-efficient. In PoS systems, validators are often chosen randomly but with a higher chance for those who hold more coins. PoS helps to maintain the integrity and security of the blockchain without the extensive energy use associated with PoW.


A crypto pre-sale is an event where a new cryptocurrency or token is sold to investors before it is made available to the general public. This stage usually occurs after the initial development of the cryptocurrency and before its official launch or Initial Coin Offering (ICO).

During a pre-sale, these tokens are often offered at a lower price or with other incentives to attract early investors. The purpose of a pre-sale is to raise funds for the further development of the project and to gauge the interest of potential investors. It’s important for investors to conduct thorough research before participating in a pre-sale, as such investments can be risky and the value of new cryptocurrencies is highly unpredictable.

Pump & Dump

“Pump and Dump” in the context of cryptocurrency refers to a manipulative scheme where the price of a crypto asset is artificially inflated (pumped) by a group of individuals or an entity through misleading or false statements, or coordinated buying.

Once the price has been pumped and reaches a higher level, these individuals then sell (dump) their holdings at the inflated price. This selling typically causes the price to crash, leaving other investors, who bought in at the higher price based on the hype, with significant losses.

Pump and dump schemes are illegal and unethical, and they are a form of market manipulation. They are more prevalent in crypto markets due to less regulation compared to traditional financial markets.

Relay Chain

A “Relay Chain” in cryptocurrency is the central chain in a blockchain network that interconnects various individual blockchains, known as parachains. This concept is prominent in the Polkadot network. The Relay Chain is responsible for the network’s security, consensus, and cross-chain interoperability.

It allows different parachains with diverse functionalities and structures to communicate and transfer value or information in a secure and trust-free manner. The Relay Chain achieves this while maintaining high scalability and efficiency by offloading most of the transactional and computational work to the connected parachains. This design enables various blockchains to work together seamlessly within a single ecosystem.

Satoshi Nakamoto

Satoshi Nakamoto is the pseudonymous person or group of people who created Bitcoin, the first decentralized cryptocurrency, and authored its original white paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System” in 2008. Satoshi also developed the first blockchain database as part of Bitcoin’s implementation.

Satoshi’s true identity remains unknown, and they have become a legendary figure in the cryptocurrency world. The smallest unit of Bitcoin, the “satoshi,” is named in their honor. Satoshi’s contribution to digital currency and blockchain technology has had a profound impact on finance, technology, and the global economy.


A crypto scam refers to fraudulent activities in the cryptocurrency market. These scams can take various forms, such as fake ICOs (Initial Coin Offerings), Ponzi schemes, phishing attacks, and fraudulent investment platforms.

Scammers often lure investors with promises of high returns, manipulate cryptocurrency prices, or steal sensitive information to access digital wallets. Due to the decentralized and somewhat unregulated nature of cryptocurrencies, these scams are prevalent and can result in significant financial losses for victims.

It’s crucial for individuals to exercise caution, conduct thorough research, and use reputable platforms when engaging in crypto-related activities to avoid falling victim to such scams.


Crypto shilling refers to the practice of aggressively promoting a cryptocurrency for personal gain, often in a misleading or deceptive manner. This can involve individuals or groups hyping up a specific crypto asset on social media, forums, or other platforms to increase its price or trading volume.

The intent is usually to create artificial excitement or FOMO (fear of missing out) to persuade others to buy the asset, thus inflating its value. After the price rises, those who were shilling the asset might sell their holdings for a profit. It’s important to be wary of such practices, as they can lead to financial losses for those who invest based on these exaggerated or false promotions.


“Shitcoin” is a colloquial term in the cryptocurrency community, typically used to describe a cryptocurrency that is considered worthless, has no clear purpose, or is deemed to be a poor investment. These are often cryptocurrencies with little to no technological or unique business advantage, minimal or no real-world use, and are sometimes created as jokes or scams.

The term can also be used to describe coins that have seen significant price drops and are not expected to recover. It’s a derogatory term that reflects the skepticism or criticism of certain cryptocurrencies within the diverse and volatile crypto market.

Stable coin

A stablecoin is a type of cryptocurrency that is designed to have a stable value, as opposed to the high volatility typically seen in cryptocurrencies like Bitcoin or Ethereum. This stability is usually achieved by pegging the stablecoin’s value to a more stable asset, such as a fiat currency (like the US Dollar or Euro), commodities (like gold), or a basket of assets.

The most common type of stablecoins are fiat-collateralized stablecoins, where each coin is backed by an equivalent amount of fiat currency held in reserve. This linkage helps reduce price fluctuations, making stablecoins a more reliable form of digital currency for everyday transactions, remittances, and as a safe haven for crypto investors during market volatility.


Crypto staking refers to the process of actively participating in transaction validation on a proof-of-stake (PoS) blockchain. In this system, instead of miners, validators are chosen to confirm transactions and create new blocks based on the amount of cryptocurrency they hold and are willing to “stake” or lock up as collateral.

Staking helps secure the network and in return, stakers earn rewards, typically in the form of additional coins or tokens.

This is considered a less energy-intensive alternative to the proof-of-work (PoW) mechanism used in networks like Bitcoin. Staking not only supports the blockchain network’s security and efficiency but also allows coin holders to earn passive income from their holdings.


A crypto testnet is an alternative blockchain used for testing purposes. It’s a separate network that mimics the main blockchain network (mainnet) but is used specifically for experimentation and development without risking real funds. In a testnet, developers can test new features, run experiments, and detect bugs or vulnerabilities in a controlled environment.

The coins used on a testnet have no real value, allowing developers and users to simulate transactions and smart contract execution without financial risk. Testnets are crucial for the development and smooth functioning of blockchain projects, ensuring that any major updates or changes are thoroughly tested before being deployed on the mainnet.


A crypto token is a type of cryptocurrency that represents an asset or specific use and resides on its own blockchain. Tokens can be used for investment purposes, to store value, or to make purchases.

Unlike cryptocurrencies like Bitcoin or Ethereum, which are intended to be used as digital currencies, tokens are often issued within a specific project or ecosystem and can have various uses such as utility, governance, or representation of an asset.

They are created through a process called an Initial Coin Offering (ICO), similar to an Initial Public Offering (IPO) in the stock market. Tokens can be built on existing blockchain platforms like Ethereum, which supports the creation of tokens through its ERC-20 and ERC-721 standards, among others.

Total Supply

Crypto total supply refers to the total amount of a cryptocurrency that currently exists or will ever exist. This includes all coins or tokens that have been mined or created and are in circulation, as well as those that are yet to be released but will eventually be part of the market.

The total supply can vary greatly between different cryptocurrencies. Some, like Bitcoin, have a capped total supply, meaning there’s a maximum number of coins that will ever be created.

Others might have a dynamic supply policy, allowing for new tokens to be created under specific conditions. Understanding the total supply is important for investors as it can influence the value and scarcity of a cryptocurrency.


A crypto transaction is the process of transferring cryptocurrency from one account (or address) to another within the blockchain network. This involves the sender initiating a transaction, specifying the recipient’s address and the amount of cryptocurrency to be transferred.

Each transaction is then verified and recorded in a block by network participants (like miners in Bitcoin or validators in proof-of-stake systems). Once a transaction is confirmed and added to the blockchain, it becomes immutable, meaning it cannot be altered or reversed.

This ensures the integrity and security of the transaction. Crypto transactions are known for their speed, global reach, and often lower fees compared to traditional banking systems.

Transaction Fee

A crypto transaction fee is a charge that users have to pay to make a cryptocurrency transaction. This fee is used to compensate blockchain network participants (like miners in Bitcoin or validators in proof-of-stake systems) who validate and record transactions on the blockchain.

The fee amount can vary based on the network’s congestion, the transaction’s complexity, and the blockchain protocol. Some blockchains have higher fees due to more intensive computational requirements, while others may have lower fees.

Paying a higher transaction fee can also result in quicker transaction processing, as miners or validators are incentivized to prioritize transactions with higher fees. Transaction fees are essential for maintaining the security and efficiency of the blockchain network.


“Crypto volatile” refers to the characteristic of cryptocurrencies to experience rapid and significant price fluctuations within short periods.

This volatility means that the value of cryptocurrencies can increase or decrease dramatically over a very short time, often influenced by factors such as market demand, investor sentiment, regulatory news, technological advancements, and broader economic factors.

The high volatility in cryptocurrencies contrasts with traditional fiat currencies, which generally see much more stable prices. While this volatility can present opportunities for high returns, it also carries substantial risks for investors and traders.


Crypto volatility refers to the characteristic of cryptocurrencies to experience significant and rapid fluctuations in value. This means the prices of cryptocurrencies can swing widely and unpredictably over short periods.

Factors influencing this volatility include market demand, investor sentiment, regulatory news, technological developments, and macroeconomic trends. Crypto markets are known for their higher volatility compared to traditional financial markets, which can lead to substantial gains or losses for investors and traders.

This volatility is partly due to the nascent and evolving nature of the cryptocurrency market, its relatively low liquidity, and its sensitivity to speculative trading.


A crypto wallet is a digital tool that allows you to store, send, and receive cryptocurrencies like Bitcoin, Ethereum, and others. It doesn’t actually store the physical coins; rather, it saves the cryptographic keys – private and public keys – that provide access to your crypto holdings on the blockchain.

The private key is like a password that gives you access to your cryptocurrencies, making security crucial. Wallets come in various forms: they can be software-based (like mobile apps or desktop programs), hardware-based (physical devices), or even paper wallets (printed keys). They are essential for managing your cryptocurrency assets and performing transactions in the crypto ecosystem.


A crypto whitepaper is a comprehensive document presented by a blockchain project that outlines the concept, objectives, technology, and details behind the project. It typically serves as a technical and marketing document designed to inform and attract potential investors, users, and enthusiasts.

The whitepaper explains the problem the project aims to solve, how the blockchain technology and the proposed cryptocurrency or token will address this problem, the economic model, the technical architecture, and often the roadmap for development and growth.

For many projects, including well-known ones like Bitcoin, the whitepaper is the foundational document that lays out the vision and technical underpinnings of the project.

Zero Confirmation Transaction

A crypto zero confirmation transaction refers to a cryptocurrency transaction that has been broadcast to the network but has not yet been confirmed or recorded on the blockchain. In simpler terms, it’s a transaction that has been initiated and is visible but hasn’t been included in a block and verified by network participants, like miners or validators.

These transactions are considered less secure because they haven’t undergone the usual confirmation process that prevents issues like double spending. However, zero confirmation transactions are sometimes accepted by merchants or individuals for small or time-sensitive payments, trading increased risk for convenience and speed. The level of risk depends on the specific cryptocurrency and its network.
