I am going to answer these questions, you can chose to believe me or not.
First point you are assuming it started today. And, it didn't. The selling pressure was tested on 10/29 and then a full press was on 11/07. The reason it collapsed today was because today was the first day there were a lot of shares to be taken on loan.
Well, because the natural state of this stock was flat, trending down slightly. As soon as the everyone covered it returned to buoyancy. I have already demonstrated why it wouldn't cross $2.50. It bounced off of $2.65 today.
The volume is because of all the selling. People are showing interest. But, most people are traders not investors. This is true for most stocks not just the OTC.
See above. Most likely this will drift closer to $1.85 though.
