Note the regions;
1. Russian Federation
6. United States
If you are worried Bitcoin will collapse because "they" will just make it illegal, many of these countries are unlikely to do that. Note the US is number 6! That's great news, even with the US' humongous economy Bitcoin has a bigger following in 5 other jurisdictions!
Switzerland will probably want to attract tax shy money for decades to come, I doubt they'll declare it illegal.
I've said it before; if Bitcoin succeeds in one economy it has succeeded globally. Nothing but the most totalitarian of regimes would be able to outlaw it.
PS I'm not referring to price collapse, that might still happen a few times before the game is over.
