Bitcoin (BTC) is a decentralized digital currency that operates without a central authority, using blockchain technology to record transactions. Launched in 2009 by an anonymous entity known as Satoshi Nakamoto, Bitcoin was designed as a peer-to-peer financial system. It enables users to send and receive payments securely and transparently across borders. Bitcoin's supply is capped at 21 million coins, making it deflationary and often compared to digital gold. Its value is driven by supply and demand, market sentiment, and macroeconomic factors. While it has faced criticism for volatility and environmental impact, Bitcoin remains the most widely recognized and adopted cryptocurrency, influencing the development of the broader crypto and decentralized finance (DeFi) ecosystem#btc
