#BitwiseBitcoinETF Bitcoin is an electronic currency created in 2009 by Satoshi Nakamoto. The name is also associated with the open-source software he designed, and also uses a peer-to-peer network with no centralized storage or single administrator where the United States Department of the Treasury calls bitcoin a decentralized currency. Unlike most currencies, bitcoin does not depend on trusting a central issuer. Bitcoin uses a distributed database spread across nodes of a P2P network to journal transactions, and uses cryptography to provide basic security functions, such as ensuring that bitcoins can only be spent by the person who owns them, and never more than once.
