Bitcoin (BTC) was the first cryptocurrency ever created back in 2009, and it remains the most popular and valuable digital currency in the world today. Bitcoin is a blockchain-based decentralized digital currency powered by a network of users who verify and record transactions without relying on a central authority or intermediary.
Bitcoin is an alternative to fiat currencies, such as the U.S. dollar, that are controlled by governments and central banks. Transactions are verified via a process known as a proof-of-work consensus mechanism. Bitcoin miners compete to verify transactions by solving complex mathematical functions using powerful computers.
