Bitcoin is a decentralized cryptomoeda, constituting an alternative economic system (peer-to-peer electronic cash system). Initially presented in 2008 on the Cryptography Mailing mailing list [10] by a programmer or group of programmers under the pseudonym Satoshi Nakamoto, is considered the world's first decentralized digital currency [15]. ] and responsible for the resurgence of the free banking system. [16]Bitcoin allows financial transactions without intermediary, but verified by all users (nodes) of the network, which are recorded in a distributed database, called blockchain.The decentralized network or alternative economic system Bitcoin has the peer-to-peer (P2P) topology, [17] ie a structure without a central administrative entity, which makes it impossible for any financial or governmental authority to manipulate the issue and value of bitcoins or induce inflation with the production of more money. [18] [19] However, large speculative movements of supply and demand influence the fluctuation of their value in the foreign exchange market, being freely defined during the 24 hours of the day. That is, the value of the crypto currency is not derived from fiduciary currencies or other assets, that is, it is not backed by any asset; Bitcoin is the commodity, it is the asset itself unprecedented.
