....They are probably afraid of bitcoin because it's a way of hiding money from the oligarchs - can't take a cut of money you don't know exists!

I think you are badly mistaken here. BTC and other cryptocurrencies are great for oligarchs. Just look
at the recent events in the Ukraine. The cabinet members had to disclose their BTC holdings and there
were many ministers, who owned the BTC equivalent of several million $ or more.
And this is only what has been published, many people probably haven´t been caught or didn´t report their full cryptocurrency holdings.
I assume that the politicians in Russia are as heavily involved as their Ukrainian equivalents.
If you would get a bribe would you prefer a BTC payment or a wire transfer?
