Bitcoin (BTC) is a decentralized digital currency that operates without a central authority. Created in 2009 by an anonymous person or group using the pseudonym Satoshi Nakamoto, Bitcoin allows peer-to-peer transactions through blockchain technology. It relies on cryptographic proof rather than trust, making it secure and transparent. Bitcoin transactions are recorded on a public ledger and validated by miners using a consensus mechanism called proof-of-work. With a capped supply of 21 million coins, Bitcoin is often seen as a hedge against inflation. It has sparked the development of thousands of other cryptocurrencies and revolutionized global finance and digital ownership.
