Forget oil, Russia goes crazy for cryptocurrency

Marinichev's virtual currencies mining farm operates in a former Soviet-era car factory warehouse in Moscow.

Standing in a warehouse in a Moscow suburb, Dmitry Marinichev tries to speak over the deafening hum of hundreds of computers stacked on shelves hard at work mining for crypto money. 

"The form of currency we are used to is about to disappear," predicts the 42-year-old entrepreneur, who also works as President Vladimir Putin's adviser on Internet matters.
