$BTC Bitcoin (#BTC) is a decentralized digital currency that operates without a central authority, such as a bank or government. It was created in 2009 by an anonymous person or group under the pseudonym Satoshi Nakamoto. BTC uses blockchain technology, a secure and transparent ledger, to record transactions. Unlike traditional money, Bitcoin is limited to 21 million coins, making it scarce and potentially valuable over time. It is used for online purchases, investment, and even as a hedge against inflation. Transactions are verified by a network of miners who solve complex mathematical problems. Despite its volatility, Bitcoin remains the most popular cryptocurrency. #Bitcoin #Crypto #Blockchain #DigitalCurrency
