$BTC $BTC, short for Bitcoin, is the first and most well-known cryptocurrency in the world. Launched in 2009 by the mysterious Satoshi Nakamoto, Bitcoin introduced the concept of decentralized digital money powered by blockchain technology. It allows peer-to-peer transactions without the need for a central authority like banks. Bitcoin is often seen as "digital gold" due to its limited supply of 21 million coins and is used both as a store of value and an investment asset. While its price is highly volatile, $BTC continues to gain popularity worldwide, attracting investors, institutions, and tech enthusiasts looking for financial freedom.
