$BTC Bitcoin ($BTC) is the first and most well-known cryptocurrency, introduced in 2009 by the anonymous creator Satoshi Nakamoto. It operates on a decentralized peer-to-peer blockchain network, allowing users to send and receive value without needing banks or intermediaries. Bitcoin's limited supply of 21 million coins makes it scarce, which contributes to its appeal as “digital gold.” Many investors view BTC as a hedge against inflation and a store of value. Its price is highly volatile, influenced by market sentiment, regulation, adoption, and macroeconomic factors. Bitcoin continues to be a driving force in the growth and recognition of the cryptocurrency industry.
