The company may start back up again, or do a reverse merger into another private company in the future? Both of which would be good for you. Most likely it will be pumped again before that ever happens. Traders know that this moves easy with volume and different groups may decide to run this again.
Hopefully you did not stick all of your money into just this one stock and you have other money to make trades with. This way you can build your account back up while you wait for this to move again. Which I am sure it probably will go back up again in the future.
By the way I have been where you are at. It happens to the best traders. Don't give up or let this stop you from trading. Trading is where you can make some extremely good money with little effort! Look at ATRN that ran from .012 to .03 cents yesterday! Probably will run again today!
