$BTC (Bitcoin) is the world's first decentralized digital currency, operating on a transparent public ledger called the blockchain. It enables peer-to-peer transactions without central authority, like banks.
Currently, BTC is hovering around $103,000, down slightly from yesterday but up significantly (around 59%) from a year ago. Its price is known for volatility, influenced by market sentiment, institutional demand (e.g., ETFs), and its limited supply of 21 million coins. Bitcoin's unique properties make it a fascinating asset for investors and a pioneer in digital finance.
