Correct, so even if your mythical ASIC miners are willing to sell at $2 a bitcoin, doesn't mean anyone else will be
Mythical? You do know that there's at least one person using ASICs since several months back - just as he began using GPUs before everyone else?
Anyway, I don't know why you believe Bitcoin wouldn't follow free market rules but the answer is that it would indeed cause a downwards price pressure.
Did the price crash when ppl started using GPUs?
Back then people weren't as price obsessed (may - sept 2010)
