Cryptocurrency is a type of digital or virtual currency that uses cryptography for security. Unlike traditional currencies issued by governments (fiat currencies), cryptocurrencies operate independently of any central authority. They utilize blockchain technology to gain decentralization, transparency, and immutability. Bitcoin was the first cryptocurrency created in 2009, and since then, thousands of other cryptocurrencies have been developed, each with its unique features and uses. People can buy, sell, and trade cryptocurrencies on online platforms called cryptocurrency exchanges.
