You are assuming that the price rise is due to short term speculators looking to make a quick buck. I think a lot more people are buying into the philosophy, politics, and revolutionary technology and won't be so quick to sell.
I think that most people buying know fairly well that it can crash, so they dont acquire more than they are willing to loose completely. So in the event of a crash, they are not necessarily going to sell, they might just keep them around in the hope that it will go up later.
