Bitcoin (BITCOIN) - a digital protected currency, more precisely - a crypto currency. It does not have the usual equivalent for us of gold, diamonds or bundles of banknotes stored somewhere. And its value is determined only by the value of all goods and services offered with payment through bitcoin.
According to the description, the output of the first client program and the actual launch of the currency service network into "independent navigation" took place in 2009. And already in May 2010, the first purchase using BITCOIN - 2 pizzas for 10 thousand bitcoin coins was made. For an incomplete 4 years, the Bitcoin course has grown a million times!
The BITCOIN service system does not have a central authority, it is not officially registered in any state. It does not have special centralized servers for storing and processing operations (transactions) - all this work is done on the computers of network participants all over the world.
