Bitcoin is a new form of money that is completely independent of centralized companies (banks, governments, etc.). It was created back in 2008 during the financial crisis here in America. It was the first digital currency to come to market in the world. Bitcoin continues to be the most decentralized [owned by the people of the world - Peer to Peer (P2P)], secure, private, auditable, cannot be counterfeited, and finite (limited to 21 million to be made for total supply) on the planet.
