it's really a mystery what will happen. If goverments will start to control bitcoin like they do with fiat currencies, or ban it entirely, the price may acctually drop. I really hope this doesn't happen.
On the other hand I would really prefer if the price of bitcoin stopped at what it ist now. The variability in BTC price is really bad, `cause services are affraid to accept it as a currency, as it is risky. Little more stability would really help bitcoin to be widely accepted imho.
