I agree with ihrhase wholeheartedly about the government. The government doesnt like competition and if you do enough to get their attention, they'll spare no cost to bring the network down. Sad but true. It doesnt even matter if its legal or illegal. Legality has nothing to do with it. The US government always has and always will bend laws or manufacture crimes to make an example of those who contest its power in any way shape or form. I dont agree with the US Government one bit but when it comes to the government the old maxim is true. Whoever has the gold makes all the rules.
So until things changes, we're all criminals whenever the government decides so. And Im not just referring to Bitcoin or its users.
As to bitcoin's value, its all a matter of basic economics... Supply VS Demand. Currently I see a lot of supply but almost no demand. Unless demand is created in volume nothing else matters. With excess supply and little demand...there is very little value and it will remain so until demand is created. If the demand doesnt increase proportionally to the supply IE if supply increases and demand stays the same or lessens then value will decline of course.
People tend to make economics far more complicated than it really is.
Sorry DwDollar but Ihrhase has it on the nose with what he's saying.
