It surely won't rise.
Ah... 70 more minutes before we get to watch the pigs get slaughtered.
Of course the price will rise.
You and others will try to sell immediately. The savvy investor knows the suckers will be trying to sell. CASH has been tied up in Mt. Gox for a week. (Bitcoins were freed yesterday, but not so much the cash.... hard to move your whole cash position to TradeHill... easier to wait until today's Mt Gox open).
Savvy investors will be buying up Bitcoins from the amateurs. And some of you will sell your whole position at 15. And when you see the price hit 17, and then 18, and the world didn't end, then you'll be buying back in at 18... And you'll drive the price up over 20. Before it's all over, some amateurs will be out at 15 and back in at 25. Sell low, buy high. Good move!
Then again, what do I know! Trust your instincts! Others will appreciate it.
Why would you not have a poll option greater than 10? Like "It will rise, not fall."
