#SpotVSFuturesStrategy Bitcoin (BTC) is the first and most popular cryptocurrency, created in 2009 by the anonymous figure Satoshi Nakamoto. It is a decentralized digital currency that operates without a central authority, using blockchain technology to record transactions publicly and securely. Bitcoin is often called "digital gold" due to its limited supply of 21 million coins and its use as a store of value. It enables peer-to-peer transactions worldwide with low fees and high transparency. Over the years, Bitcoin has gained mainstream attention as both an investment asset and a tool for financial freedom in decentralized finance (DeFi).
