I'd say people aren't anymore or less greedy than they were before. Many people believe we simply had a much needed correction, and a bottom arrived in the 50s. There is plenty of media still taking bitcoin seriously rather than just dismissing it as a failed bubble. They discuss volatility and 'last weeks high' rather than laughing it off. That causes other people to take is seriously too including the 20,000+ a day of new people signing up to MtGox. Many of these people are get quick rich newbs, but plenty of others will genuinely love the concept and will join as new 'true believers.'
If Bitcoin is to grow, then it must stagnate and find a stable base at any given price. I would suggest that it would be very unlikely that this stable base remains around the $100 mark, as their as still plenty holders of Bitcoins seeking short term profits and once these hands see that Bitcoin isnt going anywhere anytime soon, they will pull out, thus lowering the price further. Such people may be those who rushed in to capitalise on the dead cat bounce, those who have already seen the opportunity to make glittering profits and seen their equity savagely reduced, or indeed those who have infact lost money on bitcoin (often the most stubborn sellers). As it becomes obvious that the price is only going to slip lower over time, practically everyone holding Bitcoin as a store of value will seek to take some gains and or cut losses.
Whatever the price turns out to be, a stable baseline price is needed in order that real Bitcoin economic transactions have time to recover (yes, many business people have been totally fucked over by the April crash, as was totally predictable, just nobody knew for sure when this would happen), and time to further develop itself which will result in a steady flow of price insensitive Bitcoin users, i.e. people like myself who buy them and then spend them right away, rendering anything other than wild flucatations as inconsequential to our financial health. Either this happens, or Bitcoin continues to be hijacked by the spirit of parasitic speculation, which will destroy the fundamentals upon which Bitcoin relies, and the whole thing goes up in smoke and goes down n history alongside Dutch Tulips and French Colonial Bondsi as another classic lesson in self imploding speculative mania.
