Brief summary of crypto currency

A cryptocurrency is a digital currency, which is an alternative form of payment created using encryption algorithms. The use of encryption technologies means that cryptocurrencies function both as a currency and as a virtual accounting system.
What is a token

Technically, “token” is just another word for “cryptocurrency” or “cryptoasset.” But increasingly it has taken on a couple of more specific meanings depending on context. The first is to describe all cryptocurrencies besides Bitcoin and Ethereum (even though they are technically also tokens). The second is to describe certain digital assets that run on top of another cryptocurrencies’ blockchain, as many decentralized finance (or DeFi) tokens do. Tokens have a huge range of potential functions, from helping make decentralized exchanges possible to selling rare items in video games. But they can all be traded or held like any other cryptocurrency.
