Unlike nation’s currency, Bitcoin is a form of digital currency which is created and held electronically. They are not printed like any other currency as they are lines of computer code. They are digitally signed each time they travel from one owner to the next. Also, transactions can be made anonymously as no one controls it. Bitcoins are mined, using computing power in a distributed network. This network also processes transactions made with the virtual currency, making bitcoin its own payment network.
