$BTC Bitcoin (BTC) is the world’s first and most widely recognized cryptocurrency, created in 2009 by an anonymous figure known as Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology, allowing users to send and receive digital currency without the need for intermediaries like banks. Bitcoin has a capped supply of 21 million coins, contributing to its scarcity and appeal as "digital gold." Its price is highly volatile, influenced by factors like investor sentiment, regulatory news, and macroeconomic trends. Over time, Bitcoin has evolved from a niche experiment into a major asset class and store of value.
