Bitcoin is a revolutionary invention of the last decade. Its essential meaning is money digitization.

It became the first decentralized peer-to-peer payment network for using without any central authority or middlemen. In a nutshell, bitcoin is the money for Internet. Its original purpose is providing all people with universal currency for different operations. Bitcoin can also be described as the most prominent triple entry bookkeeping system in existence. Bitcoin has already changed people's understanding of currency, payment and monetary system in whole. Its crucial feature is that there is no need in third party actions as people make peer-to-peer (P2P) payments just in 10 minutes, unlike credit cards which can take up to weeks to process payment.
