$BTC
Bitcoin (BTC) is a decentralized digital currency that operates without a central authority or bank. It was introduced in 2009 by an anonymous person or group known as Satoshi Nakamoto. Bitcoin uses blockchain technology to record transactions on a public ledger, ensuring transparency and security. Users can send and receive BTC through a peer-to-peer network, and transactions are verified by network nodes through cryptography and mining. Bitcoin is often seen as digital gold due to its limited supply of 21 million coins. Its value is highly volatile but continues to attract investors and technology enthusiasts worldwide.
