About Bitcoin
Bitcoin is the world's first decentralized digital currency, created in 2009 by the pseudonymous Satoshi Nakamoto. It enables peer-to-peer value transfer without banks or intermediaries, secured by a proof-of-work consensus mechanism and recorded on a transparent public blockchain. Bitcoin has a fixed maximum supply of 21 million BTC, making it a deflationary asset increasingly used as a store of value, macro hedge, and institutional reserve asset. Its four-year halving cycle reduces new supply issuance roughly every 210,000 blocks, creating programmatic scarcity. Bitcoin is held by sovereign nations, publicly listed companies, and hundreds of millions of individuals worldwide.
