$ETH Bitcoin (BTC) is a decentralized digital currency created in 2009 by an anonymous entity known as Satoshi Nakamoto. It operates on a peer-to-peer network using blockchain technology, a public ledger that records all transactions securely. Bitcoin eliminates the need for intermediaries like banks, allowing users to transfer funds directly. It is secured by cryptographic principles and relies on a process called mining, where powerful computers validate transactions. With a fixed supply of 21 million coins, Bitcoin is often referred to as “digital gold” and is widely used for investment, remittances, and online payments. Its value fluctuates due to market demand, regulation, and adoption trends.
