I don't believe the question can be intelligently answered, or at least addressed, until we get a handle on what, specifically, drives the price of a Bitcoin.  This is the component of it that drives me crazy.  Why do we think that more widespread acceptance will make the price go up, or this or that government taking a benign position on it, or whatever? 

Let me put it this way...a dollar has the same "price", the same buying power, the same "value", whether a hundred thousand merchants accept it or a hundred million merchants accept it.  The relative general acceptance of the dollar has nothing to do with its price or value.  It certainly is a stablizing force, but not a price mover.  I can't wrap my head around what, precisely, is driving the price of Bitcoin, up or down, other than the actions of a few wealthy Chinese speculators at this point.

Please, if I'm missing something damn simple, explain it to me.  I would love to comprehend a connection between some market fundamental and the Bitcoin price.
