Forget oil, Russia goes crazy for cryptocurrency

MOSCOW, Russia - 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.
Marinichev is one of Russia's leading crypto-businessmen at the helm of operations in this facility larger than a football pitch located in a former Soviet-era car factory, which collects virtual money on the accounts of its clients.
Individuals, or firms like Marinichev's, provide the computing power to run the so-called blockchain which records the world's virtual money transactions. In return for providing that service they receive virtual money, of which bitcoin is the most popular, as payment -- a process bitcoiners call "mining".
Mining farms like this represent a growing craze in Russia for bitcoin and other virtual currencies not backed by governments or central banks that are increasingly used for goods and services on the internet.
