Russia is not USA.
Yes, I know, you probably have a short position, but no, Russia is not USA and actually has no power to seize something outside.
I have no position. I do have 18K USD on Bitstamp, which I consider to be the most trustworthy and best run of all the major Bitcoin exchanges.
Also, I don't think a short position would help me very much in a scenario where exchanges start disappearing off the scene.
