Trying to panic the bitcoin market is a dangerous game. That appears to be a game played by someone yesterday. For those that panicked and sold yesterday, I hope that you weren't risking more on bitcoin than is prudent at this stage of development. I also hope you are able to recognize it for what it really is: someone or a group trying to manipulate the market to their advantage or scare people away from bitcoin.
If you were panicked out, I hope that you will re-assess the amount of risk you're willing to take on bitcoin and, if you still desire, are able to recover some or all of the position you lost before the price rebounds.
Trying to manipulate a digital commodity a dangerous game for would-be manipulators. If panic was your objective, you may well have succeeded, but the market will learn and adapt from this. In the future, panic might not be so easily achieved and you may spend a lot to try and generate a panic and fall well short of your goal.
A digital commodity like bitcoin is a far different animal than a physical commodity where most of the trading is in various derivative paper contracts (due to the obvious cost of taking physical possession). With paper derivatives, a lot of firepower can be brought to bear on the market with relatively little capital. Since it is possible and cost effective to take possession of bitcoins, people will want to take possession of them. This means that naked shorting (in all it's various forms) will be nearly impossible with bitcoin (perhaps on very, very minuscule time frames). So inducing a panic will be a very capital intensive affair...and when the market becomes more educated in this area, it will be the market the takes advantage of the people trying to create panic.
