ADA
Cardano's native cryptocurrency (ADA) serves as the backbone of the Cardano ecosystem, named after Ada Lovelace, a 19th-century mathematician. The token plays a crucial role in the network's proof-of-stake consensus mechanism, allowing holders to delegate their tokens to stake pools or run their own pools to participate in network validation and earn rewards. It's designed to be a more energy-efficient alternative to proof-of-work cryptocurrencies.
ADA also functions as the primary medium of exchange within the Cardano ecosystem, enabling users to pay for transaction fees, participate in governance decisions, and interact with smart contracts and decentralized applications (dApps) built on the platform. The token's supply is capped at 45 billion units, making it a finite resource with built-in scarcity mechanics similar to Bitcoin.
Address
A unique identifier that serves as a destination for cryptocurrency transfers, similar to an email address or bank account number. Cryptocurrency addresses are typically long strings of alphanumeric characters derived from the user's public key using a hashing function.
Each blockchain network has its own address format. For example, Bitcoin addresses start with '1', '3', or 'bc1', while Ethereum addresses start with '0x'. Addresses are case-sensitive and include built-in error checking to prevent users from accidentally sending funds to invalid addresses.
Airdrop
A marketing strategy where cryptocurrency projects distribute free tokens or coins to specific wallet addresses, often to raise awareness or reward early adopters. Airdrops can be based on various criteria, such as holding certain tokens, previous interaction with a protocol, or simply having an active wallet address.
While airdrops can be legitimate marketing tools, they have also been used in scams where malicious actors attempt to deceive users into connecting their wallets to fraudulent websites or sharing private keys.
Algorithmic Stablecoins
Altcoin
Short for "alternative coin," this term refers to any cryptocurrency other than Bitcoin. The term emerged as Bitcoin established itself as the first and most dominant cryptocurrency, making all subsequent cryptocurrencies "alternatives."
Altcoins can range from serious projects with unique technological innovations to meme coins with little practical utility. Some notable altcoins include Ethereum, Litecoin, and Cardano.

BEP-20
BEP-20 is a token standard created for the Binance Smart Chain (BSC) network, modeled after Ethereum's popular ERC-20 standard. It defines a set of rules and functions that tokens must implement to be compatible with the BSC ecosystem, including functions for transferring tokens, checking balances, and approving spending limits. This standardization ensures that BEP-20 tokens can seamlessly interact with decentralized applications (dApps), wallets, and other smart contracts within the Binance Smart Chain network.
The BEP-20 standard has gained significant adoption due to the lower transaction fees and faster processing times offered by the Binance Smart Chain compared to Ethereum. It includes mandatory functions like "transfer" and "balanceOf," as well as optional features such as token name, symbol, and decimal precision. Many popular cryptocurrencies have BEP-20 versions of their tokens to take advantage of BSC's efficiency, and the standard has become a cornerstone of the BSC DeFi ecosystem, enabling everything from token swaps to yield farming and lending protocols.
Bitcoin
The first and most well-known cryptocurrency, created by an anonymous person or group using the pseudonym Satoshi Nakamoto in 2009. Bitcoin operates on a decentralized peer-to-peer network using blockchain technology to record and verify transactions.
Bitcoin has a fixed supply cap of 21 million coins and uses a Proof of Work consensus mechanism to secure its network. It is often referred to as "digital gold" due to its perceived role as a store of value and hedge against traditional financial systems.
Bitcoin Cashh (BCH)
Bitcoin Cash (BCH) is a cryptocurrency that emerged from a hard fork of Bitcoin (BTC) on August 1, 2017, primarily due to disagreements within the Bitcoin community over scaling solutions. The core dispute centered around Bitcoin's block size limit, with BCH advocates arguing for larger blocks to enable more transactions per second and lower fees. Bitcoin Cash increased the block size from Bitcoin's 1MB to 8MB (later increased to 32MB), allowing for more transactions to be processed in each block and theoretically enabling BCH to function more effectively as a medium of exchange for everyday transactions.
Bitcoin Cash maintains many of Bitcoin's original characteristics, including the same proof-of-work mining algorithm and the 21 million maximum supply cap, but diverges in its approach to scaling and network development. Supporters of BCH argue that it better fulfills Satoshi Nakamoto's original vision of peer-to-peer electronic cash by prioritizing on-chain scaling and lower transaction fees. However, this has come at the cost of more centralized block validation due to larger block sizes requiring more computational resources. The project has itself undergone subsequent forks, most notably the split into Bitcoin Cash ABC (now simply BCH) and Bitcoin SV in 2018, reflecting ongoing debates about the best approach to scaling blockchain networks.

H
Halving (Bitcoin)
Bitcoin halving is a pre-programmed event in Bitcoin's code that occurs approximately every four years (or specifically every 210,000 blocks) where the block reward given to miners for successfully mining a new block is cut in half. This mechanism was designed by Satoshi Nakamoto as a way to control Bitcoin's supply inflation and maintain its scarcity. The process started with miners receiving 50 BTC per block in 2009, then reduced to 25 BTC in 2012, 12.5 BTC in 2016, and 6.25 BTC in 2020. The next halving is expected to occur around April 2024, which will reduce the block reward to 3.125 BTC.
The halving events are considered significant because they directly impact Bitcoin's supply dynamics and potentially its price. The reduction in new Bitcoin supply, combined with continued or increasing demand, has historically led to price increases in the periods following halvings. This is based on the economic principle of supply and demand - as the rate of new Bitcoin creation decreases while demand remains constant or grows, the price tends to rise. However, the impact of halvings also affects Bitcoin's mining ecosystem, as miners must either compensate for reduced block rewards with higher Bitcoin prices or improved mining efficiency to maintain profitability. This mechanism will continue until approximately the year 2140, when nearly all 21 million bitcoins will have been mined.

Impermanent Loss
'Impermanent loss' occurs when you provide liquidity to a decentralized exchange (DEX) and the price of your deposited assets changes relative to when you deposited them, potentially leaving you with less value than if you had simply held the assets. The term "impermanent" comes from the fact that the loss is only realized when you withdraw your liquidity - if prices return to their original ratio, the loss disappears. For example, if you deposit equal values of ETH and USDC into a liquidity pool, and ETH's price doubles, the automated market maker will rebalance your position, effectively selling some of your ETH for USDC to maintain the pool's ratio.
The larger the price divergence between the paired assets, the greater the impermanent loss. In many cases, the trading fees earned from providing liquidity can offset this loss, but in periods of high volatility or strong directional price movement, impermanent loss can exceed trading fee revenue. This is why some liquidity providers prefer to pair assets that tend to move in correlation with each other, or to provide liquidity to stablecoin pairs where price movements are minimal, reducing the risk of impermanent loss.
Initial Exchange Offering (IEO)
An 'Initial Exchange Offering' is a fundraising event administered by a cryptocurrency exchange on behalf of a startup.
