$BTC Bitcoin (BTC) is the world’s first and most widely recognized cryptocurrency, created in 2009 by the pseudonymous Satoshi Nakamoto. It operates on a decentralized peer-to-peer network without the need for intermediaries such as banks. All BTC transactions are verified by network participants using cryptographic techniques and are recorded on a public ledger called the blockchain. Bitcoin is often seen as digital gold due to its limited supply of 21 million coins and its store-of-value characteristics. Its price is influenced by supply and demand, investor sentiment, regulatory news, and macroeconomic factors. BTC can be used for transactions, investment, and as a hedge against inflation in some economic environments.
