yes. it is possible to buy Rubles as it is not banned. Whether you are going to make or lose money is another story.
CFD trading is illegal in the US. Apart from that, CFD transactions ultimately at some point need to be settled (AFAIU) in real FX.

You won't find a regulated U.S.-based broker to trade CFDs since they're banned in the U.S., but international traders still have plenty of brokerage choices. ... Step 2: Find an instrument you want to trade. ... Step 3: Fund your account and execute your trade."
