Bitcoin, often described as a crypto currency, a virtual currency or a digital currency – is a type of money that is completely virtual. It’s like an online version of cash. People can send Bitcoins to your digital wallet, and you can send Bitcoins to other people.

The history of Bitcoin started with the invention and was implemented by the presumed pseudonymous Satoshi Nakamoto, who integrated many existing ideas from the cypherpunk community. Over the course of bitcoin’s history, it has undergone rapid growth to become a significant currency both on- and offline.
