Bitcoin

Bitcoin is like a kind of digital money. It lets you send money to people over the internet, just like you would send an email. But instead of sending paper money or coins, you are sending totally digital money that only exists on computers. Nobody prints out new coins or bills, but new coins are created by special computers that are good at solving mathematical problems – these are called "miners". Just like with real money, you can use it to buy things online, like in stores or online games. But you can also send bitcoin not only to people you know, but also to strangers. So it works just like cash, only its digital!
