The longer it stays around $100 the better IMO. I think a lot of people who got spooked by the drop will be trying to buy if the price looks stable.
Alternatively, they might think the "get rich quick" opportunity has passed and not bother investing at all.
One question is out of all those new accounts appearing on Gox which were/are planning on going long and which were/are looking for a quick buck?
Another is out of all the EAs with a decent amount of coins, how many believe that they could sell now and buy back in sub 40 or less?
Personally I think the longer the price hovers at $100, the greater chance of a long slide down until the Bitcoin economy has something cheer about other than speculation. Looking at the 3 day chart on Bitcoinity it might already have begun...
