Bitcoin is the brainchild of Satoshi Nakamoto, who published a white paper on the invention on October 31, 2008, namely “Bitcoin: A Peer-to-Peer Electronic Cash System”, describing what Bitcoin is. It was on January 2009 when Version 0.1 of Bitcoin was released. And, soon, Satoshi and Hal Finney, a cryptographic activist, transacted in bitcoins.During October 2009, an exchange rate for the bitcoin was established, which was US$1 = 1,309.03 BTC. This rate was decided after framing up an equation as to how much is the cost of the electricity to run a computer, generating bitcoins.
