$BTC Bitcoin (BTC) is the world’s first and most well-known cryptocurrency, introduced in 2009 by an anonymous entity known as Satoshi Nakamoto. It operates on a decentralized blockchain, meaning no central authority controls it. Bitcoin allows peer-to-peer transactions worldwide, offering a secure and transparent alternative to traditional money. Its value is determined by supply, demand, and market sentiment, often making it highly volatile. Many see Bitcoin as "digital gold" due to its limited supply of 21 million coins. Over time, it has gained popularity as both a store of value and a speculative investment. Bitcoin continues to shape the future of finance, pushing forward innovations in decentralized technologies and digital assets.
