$BTC
Bitcoin ($BTC) is a decentralized digital currency that operates without a central authority or government. It was created by an anonymous person or group known as Satoshi Nakamoto and released in 2009. Bitcoin transactions are recorded on a public ledger called the blockchain, ensuring transparency and security. Bitcoin can be used for a variety of purposes, including as a store of value, for peer-to-peer transactions, or as an investment. Its supply is capped at 21 million coins, which contributes to its scarcity. Bitcoin has become increasingly popular over the years, attracting both individual and institutional investors.
