#BinanceTurns8 **Bitcoin (BTC)** is a decentralized digital currency that was introduced in 2009 by an unknown creator using the pseudonym *Satoshi Nakamoto*. It operates without a central authority, using blockchain technology to record all transactions securely and transparently. Bitcoin allows users to send and receive money globally with minimal fees and no need for banks. Its limited supply of 21 million coins makes it a deflationary asset, often referred to as "digital gold." BTC is widely used for investment, online payments, and as a hedge against inflation. Over time, Bitcoin has influenced global finance and inspired the rise of other cryptocurrencies.
