For bitcoin in 2018 this is definitely very terrible. During yesterday, this currency fell below $ 7,000.
This means the virtual currency has fallen by about 50 percent since the beginning of the year, because four months ago it was trading almost $ 20,000.
The latest losses are followed as a reaction to the acceleration rules of crypto-valves announced in Europe and Asia.
In Japan, two virtual exchange platforms are closed this week due to tighter controls from financial regulators in the country. The two companies failed to obtain a license from Japan's Financial Services Agency.
Japan is one of the countries where bitkoin trading and other digital currencies exploded last year.
Other popular virtual currencies, such as ether and rhythm, have also recently declined.
