$BTC Bitcoin (BTC) is the first and most well-known cryptocurrency, created in 2009 by an anonymous person or group using the name Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology, which ensures transparent and secure transactions without the need for intermediaries like banks. Bitcoin has a limited supply of 21 million coins, making it deflationary by design. It’s often seen as “digital gold” and is used both as a store of value and a medium of exchange. Bitcoin’s price is highly volatile, influenced by market demand, regulation, technological developments, and macroeconomic factors like inflation.
