Cryptocurrency is a digital or virtual currency that uses cryptography for secure financial transactions. Cryptocurrencies are decentralized and operate on a peer-to-peer network, meaning they are not controlled by any central authority, such as a government or financial institution.
The most well-known cryptocurrency is Bitcoin, but there are many other cryptocurrencies available, such as Ethereum, Litecoin, and XRP. Cryptocurrencies can be used to make purchases or transferred between individuals, and they are stored in digital wallets.
