Cryptocurrency, or simply "crypto," refers to a digital currency that uses encryption techniques to regulate the generation of units and verify transactions. The most well-known cryptocurrency is Bitcoin, which was created in 2009. Unlike traditional currencies, cryptocurrencies are decentralized, meaning they are not controlled by any central authority such as a government or a bank. Instead, transactions are recorded on a public ledger called a blockchain, which is maintained by a network of computers around the world.
