Is Bitcoin

bitcoin is an electronic currency that was launched in 2009 by a pseudonym named satoshi nakamoto.

bitcoin is used in transactions over the internet without using an intermediary alias not using bank services.

basically bitcoin uses a peer to peer (P2P) system. It's just that this system works without a single storage or administrator where the United States Treasury calls bitcoin a decentralized currency.

Unlike other currencies in general, bitcoin does not depend on one large issuer. Bitcoin uses a distributed database and spreads to nodes from P2P networks to transaction journals.
