Bitcoin (BTC) is a decentralized digital currency that operates without a central authority, using blockchain technology to enable secure peer-to-peer transactions. Created in 2009 by an anonymous individual or group under the pseudonym Satoshi Nakamoto, Bitcoin allows users to transfer value globally with low fees and without relying on traditional banks. Transactions are recorded on a public ledger maintained by a network of nodes, using cryptographic proof and mining. Bitcoin is often seen as digital gold due to its limited supply of 21 million coins, and it has become both a speculative asset and a hedge against inflation.
