$BTC $BTC is the ticker symbol for Bitcoin, the first and most well-known cryptocurrency, created in 2009 by an anonymous person or group known as Satoshi Nakamoto. Bitcoin operates on a decentralized network using blockchain technology, allowing peer-to-peer transactions without the need for intermediaries like banks. It is often referred to as digital gold due to its limited supply of 21 million coins, which contributes to its value. Bitcoin has gained popularity as a store of value and a hedge against inflation, attracting both individual and institutional investors. Its volatility and potential for high returns make it a significant player in the financial landscape.
