Cryptocurrency is a type of digital or virtual money that uses cryptography to secure transactions and control the creation of new units. Unlike traditional money issued by governments, cryptocurrencies are usually decentralized, meaning they are not controlled by a central bank or authority.

The most well-known cryptocurrency is Bitcoin, but there are thousands of others, like Ethereum, Ripple, and Litecoin. Transactions are recorded on a blockchain, which is a secure, public ledger that prevents fraud and double-spending.

People use cryptocurrency for various purposes: online payments, investing, trading, or as a way to transfer value across borders quickly. However, cryptocurrencies are highly volatile, meaning their value can rise or fall sharply in a short time, which makes them risky compared to traditional investments.
