What is Bitcoin ?
Each Bitcoin is basically a computer file which is stored in a 'digital wallet' app on a smartphone or computerPeople can send Bitcoins (or part of one) to your digital wallet, and you can send Bitcoins to other people. Every single transaction is recorded in a public list called the blockchain. This makes it possible to trace the history of Bitcoins to stop people from spending coins they do not own, making copies or undo-ing transactions. There are lots of things other than money which we consider valuable like gold and diamonds. The Aztecs used cocoa beans as money! Bitcoins are valuable because people are willing to exchange them for real goods and services, and even cash.
