Cryptocurrency is a digital or virtual form of currency that uses cryptography for secure financial transactions, controls the creation of new units, and verifies asset transfers. Unlike traditional currencies issued by central banks, cryptocurrencies operate on decentralized blockchain networks.
Bitcoin, introduced in 2009 by the pseudonymous Satoshi Nakamoto, was the first cryptocurrency and remains the most prominent. However, thousands of alternative cryptocurrencies (altcoins) now exist, each with unique features.
