"Direct investments in this area have recently exceeded $2 billion USD, in more than 500 companies. Russia is now facing a boom of cryptocurrency mining and Blockchain startups number growth." - seems like Russia is big on crypto these days
"Boom of crytocurrency mining in Russia"? Are you serious? As far as I now, there are still no regulatitons for ICOs in Russia, and according to the statements of Russian mininstery of Finance, which claims cryptocurrency to be not stable and almost illegal, I think it is still a long long way to the possible boom of it in this country.
