$BTC Bitcoin (BTC) is the pioneering decentralized digital currency, established in 2009 by the enigmatic Satoshi Nakamoto. Operating without central authority, it enables peer-to-peer transactions recorded on a public, distributed ledger called the blockchain.

Its finite supply of 21 million coins contributes to its scarcity and potential as a store of value. Bitcoin's price volatility and regulatory landscape continue to evolve, making it a subject of intense interest for investors and technologists alike. Its influence has spurred the creation of thousands of other cryptocurrencies, solidifying its place as a transformative innovation in finance.
