Bitcoin

Bitcoin is the first and most well-known cryptocurrency, created in 2009 by an anonymous entity known as Satoshi Nakamoto. It operates on a decentralized digital ledger called the blockchain, allowing peer-to-peer transactions without the need for intermediaries like banks. Bitcoin is often referred to as "digital gold" and is used for various purposes, including online purchases, investment, and as a store of value. It uses a process called mining to secure the network and issue new bitcoins. Its limited supply of 21 million coins contributes to its reputation as a deflationary digital asset.
