Bitcoin is a crypto currency, with the creation and the transfer of the bitcoins being based on a protocol that does not depend on the central authority. The coins can be transferred through computers or through smartphones and related devices, without the necessity of having a financial institution as an intermediate. This concept was established by Satoshi Nakamoto in 2008 and it was geared towards the world of electronic cash systems.
