The problem is not, not knowing the bitcoins. The problem is getting anything for RUB, like USD or bitcoins. There is a limit for buying USD and there is not many place to echange RUB.
You can use some indirect transfers of rouble with lots of fees. And the process is complicated.
Once You get ie. USD what to do with them? Send them back to Your account and risk it will go away ? Sure You can always send it to a bank account abroad.
Wow, some load of misinformation, from start to end not a single word of truth.
No, there is no problem buying anything for rouble. In fact, the russian exchange btc-e is one of the top exchanges in the world by volume, there are many localbitcoins high volume sellers, etc etc. The problem is, as was said above, not many people view bitcoin as a safe haven, most people with money flee to USD/EUR, and most common folk just spend their roubles on merchandise like cars and electronics while it's cheaper than anywhere else in the world.
