$ADA Bitcoin (BTC) is a decentralized digital currency that operates on a peer-to-peer network without the need for intermediaries like banks. Created in 2009 by the pseudonymous Satoshi Nakamoto, Bitcoin uses blockchain technology to ensure secure and transparent transactions. Its supply is limited to 21 million coins, making it deflationary. BTC is widely used for investment, remittances, and as a store of value, often referred to as "digital gold." It is highly volatile but has gained mainstream acceptance, with institutions and governments exploring its potential. Bitcoin's impact on finance and technology continues to evolve, shaping the future of money.
