#BTC

Bitcoin is the first decentralized digital currency, created in 2009 by the mysterious Satoshi Nakamoto. It operates on a peer‑to‑peer network using a public ledger called the blockchain—transactions are grouped into blocks and secured via proof‑of‑work mining, requiring computational effort to prevent fraud . With a fixed maximum supply of 21 million coins, BTC is often called “digital gold,” valuing scarcity and censorship resistance . It’s used both as a medium of exchange and a store of value, increasingly seen in institutional portfolios. Bitcoin’s decentralized design removes third-party control, emphasizing transparency and global accessibility .
