Cryptocurrency markets use a lot of technical language. This glossary explains key terms in plain English so you can understand platforms, guides, and market discussions with confidence.
Core Cryptocurrency Terms
Blockchain
A blockchain is a decentralised digital ledger that records transactions across many computers. Once data is recorded, it cannot easily be changed, making blockchains transparent and resistant to manipulation.
Cryptocurrency
A digital or virtual currency that uses cryptography for security. Cryptocurrencies operate independently of central banks and are typically built on blockchain technology.
Bitcoin (BTC)
The first and most widely recognised cryptocurrency. Bitcoin is often viewed as digital gold due to its limited supply and long-term store-of-value narrative.
Altcoins
Any cryptocurrency other than Bitcoin. Examples include Ethereum, Solana, and Cardano. Altcoins often focus on smart contracts, scalability, or specific use cases.
Stablecoin
A cryptocurrency designed to maintain a stable value by being pegged to an asset such as the US dollar. Stablecoins are often used for trading, payments, and transferring value.
Trading & Market Terms
Spot Trading
Buying or selling a cryptocurrency for immediate delivery at the current market price. When you trade spot, you own the actual asset.
Derivatives
Financial instruments that derive their value from an underlying asset. In crypto, derivatives include futures, options, and CFDs, allowing traders to speculate without owning the asset.
CFD (Contract for Difference)
A contract between a trader and a broker where profits or losses are based on price movement. CFDs allow trading with leverage and the ability to go long or short.
Leverage
Borrowed capital that allows traders to control a larger position with a smaller amount of money. While leverage can increase profits, it also significantly increases risk.
Spread
The difference between the buy (ask) price and sell (bid) price. The spread represents a trading cost paid to the broker or exchange.
Liquidity
How easily an asset can be bought or sold without affecting its price. High liquidity generally means tighter spreads and smoother execution.
Orders & Execution
Market Order
An order to buy or sell immediately at the best available price. Market orders prioritise speed over price precision.
Limit Order
An order to buy or sell at a specific price or better. Limit orders give more control but may not be filled if the market never reaches the chosen price.
Stop-Loss
An automatic order that closes a trade when a certain loss level is reached. Stop-loss orders are essential for risk management.
Take-Profit
An order that automatically closes a trade once a specified profit target is reached.
Wallets & Security
Crypto Wallet
A digital tool used to store, send, and receive cryptocurrencies. Wallets manage private keys, not the actual coins themselves.
Hot Wallet
A wallet connected to the internet. Hot wallets are convenient but generally less secure than cold storage.
Cold Wallet
An offline wallet used for long-term storage. Cold wallets provide stronger protection against hacking.
Private Key
A secret code that gives access to your cryptocurrency. Anyone with your private key controls your funds — it should never be shared.
Two-Factor Authentication (2FA)
An additional security step that requires a second form of verification, such as a mobile app or SMS code, when logging into an account.
Market Behaviour & Analysis
Volatility
The degree to which price fluctuates over time. Crypto markets are known for high volatility compared to traditional assets.
Bull Market
A market characterised by rising prices and positive sentiment.
Bear Market
A market characterised by falling prices and negative sentiment.
Market Capitalisation
The total value of a cryptocurrency, calculated by multiplying price by circulating supply. Market cap is often used to compare the size of different cryptocurrencies.
