Bitcoin is the largest cryptocurrency, with a total value of over $200 billion for all Bitcoins in circulation. Bitcoin was designed to be a decentralized currency, backed by no physical asset or government entity and requiring no middleman or bank to conduct digital transactions. Payments are sent via a digital ledger known as the blockchain and no personal information needs to be exchanged. Bitcoin is a purely digital asset and there are no physical Bitcoins available.
