#TrumpTariffs Bitcoin (BTC) is a decentralized digital currency that operates without a central authority, such as a government or bank. Created in 2009 by an anonymous figure known as Satoshi Nakamoto, Bitcoin uses blockchain technology to enable peer-to-peer transactions on a secure, public ledger. Each transaction is verified by network nodes through cryptography and recorded on the blockchain. Bitcoin has a limited supply of 21 million coins, making it deflationary by design. It's often seen as both a speculative investment and a store of value, like digital gold. While praised for financial freedom, Bitcoin faces criticism over energy consumption and volatility. It continues to influence finance and technology worldwide.
