$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, meaning transactions occur directly between users without the need for intermediaries like banks or governments.

All Bitcoin transactions are recorded on a public, distributed ledger called the blockchain, secured by cryptography. This technology ensures transparency and prevents fraud. Bitcoin's supply is capped at 21 million coins, making it a scarce asset often compared to digital gold. Its value is determined by market demand, leading to significant price volatility.
