#BinancePizza Cryptocurrency, or crypto, is a digital or virtual currency that uses cryptography for security and operates independently of a central authority like a government or bank. Most cryptocurrencies are based on blockchain technology—a decentralized ledger that records all transactions across a network of computers. Bitcoin, created in 2009, was the first cryptocurrency and remains the most well-known. Cryptocurrencies can be used for peer-to-peer transactions, investment, or as a store of value. They are known for their volatility, innovation, and potential for both high returns and high risks. Popular examples include Bitcoin, Ethereum, and Solana, each with unique features and use cases.
