Cryptocurrency is a digital or virtual currency that uses cryptography to secure and verify transactions as well as to control the creation of new units. Cryptocurrencies operate independently of a central bank and are based on decentralized systems that use blockchain technology to record and validate transactions. The most popular cryptocurrency is Bitcoin, but there are many other cryptocurrencies such as Ethereum, Litecoin, and Ripple.
