Bitcoin (BTC) is a new kind of digital money called a cryptocurrency or crypto. It’s powered by blockchain technology and is one of the most secure financial systems in history. Unlike the cash in your wallet, bitcoin is run by computers, not people. That means you don’t need a bank to buy it, sell it, use it, or keep it safe—all you need is an internet connection. It also means that no single person or government gets to decide who gets access to bitcoin or what it’s worth. Its price is determined by supply and demand. As the world’s leading crypto, Bitcoin is changing the way people send, save, and use money.
