Bitcoin is the world's first decentralized digital currency. This currency is fundamentally different from all previously created electronic currencies and payment systems. It is not tied to any physical assets or "official" currencies, and the price digital coin - bitcoin - market is governed solely by supply and demand.

Now the exchange rate BTC/USD:
1 BTC = ~1284.27 USD
1 USD = ~77865 Satoshis

Bitcoin is also a global payments system, through which you can perform operations with this currency. The main difference from traditional payment systems is that the Bitcoin system has no managing and processing center - all operations occur only in the network of peer clients.

The idea of cryptocurrencies "b-money" described in 1998 Wei Dai in the newsletter Shirobokov. Also suggestions made Nick Szabo called "Bitgold".

In 2008, a person or group of persons under the pseudonym of Satoshi Nakamoto published the file with the description of the Protocol and the principle of peer-to-peer network. According to Satoshi, the development started in 2007. In 2009 he completed the development of the Protocol and published the client, after which the network was launched.
Further development organizes and coordinates Gavin Andresen.
