Bitcoin (BTC) is the world’s first decentralized digital currency, created in 2009 by an unknown person or group using the pseudonym Satoshi Nakamoto. It operates on a peer-to-peer network without a central authority, using blockchain technology to securely record transactions. BTC is limited to 21 million coins, making it a scarce asset. People use Bitcoin for various purposes — from online purchases to long-term investments, viewing it as "digital gold." Its value fluctuates based on supply, demand, and market sentiment. As the pioneer of cryptocurrencies, BTC continues to shape the future of finance. #bitcoin #crypt #blockchain #BTC
