In February 2010, the network appeared the first service to buy bitcoins the Bitcoin Market, and in may the forum user of bitcoin decided to buy two pizzas for 10 thousand bitcoins. However, in July about bitcoins wrote on a popular among computer geeks portal, Slashdot, and the number of users of virtual money started to skyrocket. As a result, after a month of 10 thousand bitcoins were worth $ 600, and many netizens have begun to actively mine the cryptocurrency itself. This has led to the emergence of the first bitcoin exchange MtGox, which allowed not only to buy bitcoins, but exchange them for real money. The rate of bitcoin has grown rapidly — from 6 cents per unit in July to 50 cents in November; then the total volume of the market was estimated at $ 1 million.
