I think it could go to the very low $1 area (much lower if hit hard by SEC) before resting. I would never be a long buyer though, that is too risk along with bad management.
I guess those that buy low 1's and play possible bounces can make money, but again, very risky. The old highs I don't see happening, those we ALL inflated prices. Someone sitting on $2.50+ per share are simply wasting their time and money. Could it go up and down between low and high 1's......maybe. That would be the area I would look at if I were flipping shares.
As far as covering, probably under 1.25 area, just because it will be dead for a long while after that, not because I think it will pop back up.
