Bitcoin (BTC) is the first and most well-known cryptocurrency, created in 2009 by an anonymous individual or group known as Satoshi Nakamoto. It operates on a decentralized peer-to-peer network, allowing users to send and receive value without relying on banks or intermediaries. Bitcoin uses blockchain technology—a public ledger of transactions secured by cryptographic algorithms and maintained by miners through a process called proof-of-work. With a capped supply of 21 million coins, Bitcoin is often seen as “digital gold” and a hedge against inflation. It has influenced the development of thousands of other cryptocurrencies and remains a dominant force in the digital asset market, used for investment, payments, and decentralized finance.
