Wanted to pick USA, but if the EU starts seizing BTC, the US is not far behind - or most likely already started seizing BTC and the EU is just following.
btw, EU != Europe. Switzerland is not a part of the EU but it's in Europe
Not sure if you already know, but reading the polls looked weird to me. The options Switzerland and Malta/Somewhere in the EU except Switz. sounded more like simply Switzerland and EU.
