$BTC Bitcoin (BTC) is the world's first 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, ensuring secure and transparent transactions without the need for intermediaries like banks. Bitcoin is often referred to as "digital gold" due to its limited supply of 21 million coins. It has gained global recognition as a store of value and investment asset. BTC's price fluctuates based on supply, demand, and market sentiment. Many investors see it as a hedge against inflation, while others use it for online transactions.
