I hate Bitcoin investors

Fluctuating the damn Bitcoin price.  The SilkRoad is the true determiner of the value of the Bitcoin.  Stupid investors.

So if data-mining is how the currency is processed between users, then how do the miners get paid if there are a limited amount of bit-coins in existence to go around? What will happen to the currency when there are no miners remaining to process exchanges?
Or even worse, what if our local government pulls the plug on the internet? Don't tell me that they can't. I've seen the swtich with my own eyes.
