 Cryptocurrency.

Cryptocurrency is a digital or virtual currency that uses cryptography for security and operates independently of a central bank. Cryptocurrencies use decentralized systems, such as blockchain, to maintain a secure public ledger of all transactions and to verify and process transactions. The most well-known cryptocurrency is Bitcoin, but there are many other examples, such as Ethereum, Ripple, and Litecoin. Cryptocurrency can be used for a variety of purposes, such as purchasing goods and services, trading, and investing. Some people also see it as an alternative to traditional fiat currencies due to its decentralized nature and potential for increased privacy and security in transactions.
