Cryptocurrency is a digital or virtual currency that uses cryptography for security and operates independently of a central bank. It is decentralized, meaning it is not controlled by any government or financial institution. Some of the most well-known cryptocurrencies include Bitcoin, Ethereum, and Litecoin. Transactions made with cryptocurrencies are recorded on a public ledger called a blockchain. The use of cryptocurrencies has grown in popularity in recent years as a means of payment and as a store of value.
