Because people are playing with the stock to get people to bail out. Thats the way it is in the pinks and with this stock in particular because it has an extraordinary chance of succeeding. They're going to try to short it to death so they don't have to pay back the naked short shares. If the shareholders stay strong, they wont do it. If you can't handle the heat....you should probably bail now. People will be there to buy your shares because they know the potential of the company...JMHO
