$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 technology called blockchain. This public, distributed ledger records all transactions, secured by cryptography, without the need for a central authority like a bank.
Bitcoin's appeal lies in its fixed supply (21 million coins), making it a deflationary asset often compared to "digital gold." It enables peer-to-peer transactions globally, offering faster and cheaper transfers than traditional systems. While highly volatile, BTC continues to be the leading cryptocurrency and a significant force in the evolving financial landscape.
