Bitcoin (BTC) is the first cryptocurrency in the world, created by an anonymous figure named Satoshi Nakamoto in 2009. Its purpose is to create a decentralized digital currency system without intermediaries like banks. Bitcoin uses blockchain technology and a Proof of Work (PoW) consensus mechanism to securely and transparently record transactions. The total amount of BTC is limited to only 21 million, which makes it regarded as 'digital gold.' Bitcoin is often used as a hedge against inflation and is now receiving attention from major institutions, including through Bitcoin Spot ETFs that have been approved in the US.
