PP is necessary and is capping price - $.50 unit + news hold during placement period. There is no reason for this stock to be at .60 or .70 right now. If PP is successful, and the company starts to release more meaningful information - then there could be some upside.
I don't understand the impatience. The high SP came during a period where they saw regulatory approval and coverage from zacks. It's share structure was also quite different back then. We have not seen events like that since.
wait it out.
