$BTC Bitcoin (BTC) is a decentralized digital currency, operating on a peer-to-peer network without central authority. Created in 2009 by an anonymous entity known as Satoshi Nakamoto, it introduced blockchain technology – a secure, transparent, and immutable public ledger of all transactions. BTC's finite supply of 21 million coins makes it a deflationary asset, often compared to "digital gold." It enables fast, secure, and borderless transactions, offering an alternative to traditional financial systems. While volatile, its increasing adoption for payments, investments, and remittances highlights its evolving role in the global financial landscape.
