$BTC

Bitcoin (BTC) is a decentralized digital currency that operates without a central authority, using blockchain technology to record transactions. Created in 2009 by an anonymous person or group known as Satoshi Nakamoto, Bitcoin allows peer-to-peer transactions across the globe. It is often seen as digital gold due to its limited supply of 21 million coins and potential as a store of value. Bitcoin is highly volatile, making it popular for both investment and speculation. It has inspired the development of thousands of other cryptocurrencies and plays a central role in the broader world of decentralized finance (DeFi) and blockchain innovation.
