$BTC Bitcoin (BTC) is a decentralized digital currency introduced in 2009 by an anonymous individual or group known as Satoshi Nakamoto. It operates on a peer-to-peer network, allowing users to send and receive payments without relying on a central authority, such as a bank or government. Transactions are recorded on a public ledger called the blockchain, which ensures transparency and prevents double-spending. Bitcoin is created through a process called mining, where powerful computers solve complex mathematical problems to validate transactions and secure the network. With a limited supply of 21 million coins, BTC is often referred to as "digital gold" due to its scarcity and potential as a store of value. Over the years, Bitcoin has gained widespread attention as both an investment asset and a tool for financial freedom. Despite its volatility, it continues to influence global finance and inspire the development of other cryptocurrencies and blockchain technologies.
