$XRP 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, allowing users to send and receive payments without intermediaries like banks. Bitcoin transactions are verified by network nodes through cryptography and recorded on a public ledger called the blockchain. Its supply is limited to 21 million coins, making it scarce and often compared to digital gold. Bitcoin has become a popular investment asset and is also used for online purchases. Its price is highly volatile, influenced by market demand, regulatory news, and technological developments.
