$BTC Bitcoin (BTC) is the world’s first and most well-known cryptocurrency, created in 2009 by an unknown person or group using the name Satoshi Nakamoto. It operates on a decentralized network called blockchain, which ensures transparency and security without the need for a central authority. Bitcoin is often referred to as “digital gold” due to its limited supply of 21 million coins and its potential as a store of value. It has gained popularity as both an investment asset and a means of payment. Despite its volatility, Bitcoin continues to influence global financial markets and remains at the forefront of the cryptocurrency revolution.
