What is Bitcoin
Bitcoin is a cryptocurrency invented in 2008 with a developer under a group of programmers under the name Satoshi Nakamoto. It was released to the Internet as open-source software in 2009. A "decentralised" Internet of Money without a central bank or government control, Bitcoin's circulation is provided by a network of its clients, that have a financial incentive to make sure each transaction without an intermediary is fulfilled, recorded and secured.
Its central cohesive source is named blockchain; a visible ledger which enables anybody to verify a Bitcoin trade.
Bitcoin gained high popularity as time went by. In the Aftermath of the Cyprus Banking Crisis, Bitcoin's worth more than doubled in the spring of 2013. As investors from Asia and elsewhere started to realise the potential of this digital currency, the price of Bitcoin has ever reached USD $2900+.
