What is Bitcoin?

Bitcoin is digital money that lives on computers instead of in your wallet [2]. It's like electronic cash that you can send to anyone in the world without needing a bank [1][3].

Why is it special?

Instead of one company or government controlling the money, thousands of computers around the world work together to keep track of it [2][3]. This means nobody can cheat or fake Bitcoin because everyone's checking everyone else's work [1].

How do you use it?

You can buy things with Bitcoin just like regular money, and you keep it in a special digital wallet [1]. When you send Bitcoin to someone, the whole network checks that you actually have it before the payment goes through [3].

What's the catch?

Bitcoin's price goes up and down a lot [4], so it's risky to use for everyday shopping. You also can't get your money back if you make a mistake or someone tricks you [1][2].
