The Bank of Russia called operations with cryptocurrency a potentially dangerous, because it can be used for terrorist financing or money laundering. Russian law enforcements are also have this in mind.
However, after press-release of Central Bank the government of Russian Federation have explained that does not apply negative to bitcoin and looking for ways to control it.
So the ruble has never been used for financing terrorism or money laundering? The least these governments can do is come up with better scare tactics.
Of course, rubble, as any other currency can be used for financing terrorism, but any transaction with real currency is much easier, than absolutely anonymous operations without person behind it and without permanent IP. It's obvious, that that drug dealers perfer anonymous TOR, than operations from hand to hand, and if he tries to push heroin - results can be real horrify.
In spite of the fact that Russia is one of leaders in herion application, our politicts in point of any drugs are very tough.
