Cryptoassets are digital representations of value or rights. They typically use a shared ledger, such as a blockchain, rather than taking the form of a coin you can hold. The FCA’s introduction to crypto explains the terminology and risks.
This section of The Coin Expert explains crypto language for readers familiar with physical money. It does not recommend investments, exchanges or wallets.

A reading route for beginners
- Start with cryptoasset and cryptocurrency.

Keep definitions separate from investment decisions
Understanding a term does not establish that a product is suitable, authentic or safe. The FCA warns that crypto investments are high risk and that investors should be prepared to lose all their money. Read its consumer guidance rather than treating a familiar name as reassurance.
