OP: Please help me understand your poll.  At 118 US dollars = 1 BTC; does that equate to 3 figures (digits)?  If so then 1,000,000 US dollars = 1 BTC is the threshold you are concerned with, right?  That's a lot more demand than we have right now.  I would be very surprised if that much fiat shows up at the exchanges anytime soon.  Can *anyone* say how much fiat has been pumped into Bitcoin through the exchanges and other avenues?  The Bitcoin capitilization is something like $1.2 billion right now *but* it did not take that much fiat to get it there.  Fundamentally it is a confidence game.  If buyers believe then they will bid higher and higher.  If one buyer showed up and bought 1 BTC for $1,000,000 through an exchange that reports it then for at least a brief moment your threshold would be met.  The next exchange might happen back down in the hundreds but so be it.  Btw, I'd be delighted to be the one to sell one of my own Bitcoins to acheive this.  Or are you rejecting any and all such artificial occurances?
