Cryptocurrency is a digital or virtual form of currency that uses cryptography for security. It is a decentralized form of money that operates on a technology called blockchain, which is a distributed ledger that records all transactions across a network of computers. Unlike traditional currencies issued by governments (such as the US dollar or the Euro), cryptocurrencies are not controlled or regulated by any central authority, such as a central bank.
One of the most well-known cryptocurrencies is Bitcoin, which was created in 2009 by an anonymous person or group of people using the pseudonym Satoshi Nakamoto. Bitcoin introduced the concept of decentralized digital currency and served as the foundation for the development of numerous other cryptocurrencies, commonly referred to as altcoins.
