#CryptoStocks Bitcoin (BTC) is a decentralized digital currency that operates without a central authority, using blockchain technology to enable peer-to-peer transactions. Created in 2009 by the pseudonymous Satoshi Nakamoto, Bitcoin allows users to transfer value globally with transparency and security. It relies on a public ledger, cryptographic verification, and a process called mining to validate and record transactions. Bitcoin has a fixed supply of 21 million coins, making it resistant to inflation. Widely considered the first and most influential cryptocurrency, Bitcoin is used as both a store of value and a medium of exchange, often referred to as "digital gold."
