My point is we could see major Govt. could rush in and buy as much BTC as possible if it becomes mainstream. Major institutions are already starting to use BTC as a hedge. Only a matter of times before the really Big Boys will step in. This way the US could actually control the Global Financial System.
If the US government wanted to do that, it would have been done a long time ago before Bitcoin huge growth in price and acceptability.
Personally I think the USG actually allowed Bitcoin to grow for their own selfish reasons and the moment Bitcoin becomes a threat, they will put Bitcoin in its place.
Bitcoin might just be a tool of the US government.
