$BTC Bitcoin (BTC) is the world’s first decentralized digital currency, created in 2009 by an anonymous person or group using the name Satoshi Nakamoto. It operates on a peer-to-peer network without the need for intermediaries like banks or governments. Bitcoin transactions are verified by network nodes through cryptography and recorded on a public distributed ledger called the blockchain. With a capped supply of 21 million coins, Bitcoin is often referred to as "digital gold." It is used for various purposes, including online payments, remittances, and as an investment asset. Its value fluctuates based on market demand, technological developments, and regulatory news.
