$BTC Bitcoin (BTC) is the world's first decentralized digital currency. Created in 2009 by an anonymous entity known as Satoshi Nakamoto, it operates on a peer-to-peer network without central authority like banks or governments. Transactions are secured by cryptography and recorded on a public, immutable ledger called the blockchain.

Bitcoin's limited supply of 21 million units makes it deflationary and often referred to as "digital gold," serving as a store of value. While its price is volatile, its innovative technology has revolutionized finance, paving the way for thousands of other cryptocurrencies.
