$BTC Bitcoin (BTC) is the pioneering decentralized cryptocurrency, conceived in 2008 by the pseudonymous Satoshi Nakamoto. Launched in 2009, it operates on a peer-to-peer network, independent of central authorities. Transactions are recorded on a public, distributed ledger called the blockchain, secured cryptographically and validated by a process known as mining.

Bitcoin's price has experienced significant volatility, reaching an all-time high of around $109,000 in December 2024. As of today, April 28, 2025, the price hovers around $95,000, with a market capitalization of approximately $1.9 trillion, making it the largest cryptocurrency. Its limited supply of 21 million coins contributes to its scarcity. While initially envisioned as a medium of exchange, Bitcoin is now largely considered a store of value and an investment asset.
