price predictions, page-2

I bought 2 times before. the first time, 17.c and sell it 20.
and the last one 17c and sold it for 16.5c because i was tired waiting for volumes. Yesterday, I was in again, I paid the plus 20.5c due to the Nasdac listing I will not sell below 28c. 42c why not? but PRR dissapoint people on the last 4 months. I believe in biotechs, because it is the easy way to get good profits 100% 200% in a short time. Also is a high risk. All of us know that, the worst scenario, is that the trial resulst is not good. but we will be at 28c at this moment and many of us already take off.
