I see no reason why bitcoins won't fall back to $300 or lower now.
Lets face it, it seems the whole reason bitcoin boomed recently was China. I wish I knew just how much they were buying, but they seemed to be the big player. With the government cracking down over there and if china is pretty much out of the game, who is going to be buying $750 dollar bitcoins?
Surely not the people who bought them for $100 and lower. These people are probably the majority of the people who have the potential to buy bitcoins. They talk about going to the moon, but I doubt any of those people are going to fork $750 of their fiat dollars for a bitcoin especially when they are holding some already. They talk about going to the moon because they want their value to increase. They are not taking $750 dollars and buying a single digital coin.
More and more people should start selling their bitcoins as the price stagnates and signs point to another drop. Right now the price looks very weak and no signs of any recovery.
For their to be another speculative bubble and price to go to the moon again, bitcoin will have to lower in price enough for new people to want to buy them. The price will have to go to a level where people feel they are undervalued and another buying frenzy gets pushed forward. I don't see this happening until the price reaches at least in the $200's.
The reason for the boom is more complicated than just China (as for China, only Hong Kong, Shanghai and Beijing areas were really involved).
IMO the recovery from the SR crash (which crash was corrective wave 2) was the start point of the boom and China only strengthened the uptrend.
Once price started to rise sharply, more people got interested, and new fiat flowed into the exchanges for quite a while.
As for the price at the very bottom, I said before that it depends how many more coins will appear in the asks, right now about 51k on Gox, according to trading.i286
In April, at this stage of the market, the biggest dumps already happened, so the most important information now should be the amount of coins transferred to the exchanges.
I believe the next days will see greed turn into fear, as the buyers look weak, and more coins will appear in the ask sum, building up seller pressure.
