Bitcoin is the first and most famous decentralized digital currency, launched in 2009 by an unknown person or group known as Satoshi Nakamoto. Bitcoin aims to provide an alternative financial system that allows for direct transfers without the need for intermediaries such as banks. It relies on blockchain technology, which records all transactions transparently and securely. The maximum total number of Bitcoin units is 21 million, making it scarce and viewed as 'digital gold'. Bitcoin is produced through a process called mining, and its value is influenced by supply and demand. Investors use it as a hedge against inflation, for trading, and sometimes as a means of payment.
