Somehow, this had to happen
Having an unregulated currency in Putinland was always something of a surprise to me. When China put the kibosh on funny money, it was a "duh" moment, because of course the PRC government was not going to accept people having anything out of its control.
I think that the only reason Putin has not yet actually put his foot down on this market is because of all the blackhats he has creating mischief and mayhem everywhere else. He might lop off a head here and there, when the Western nations come crying too loudly, but otherwise it's all good for him.
Now the central bank is saying nuh-uh. It'll be interesting to see how this goes.
