However, I still don't get it, why still so many are willing to sell their shares at these levels. If they wouldn't for some penny gains, the RS would potentially be lower, as the shareprice would be allowed to settle at way higher levels.

I am not selling one single share with the current prospects. Never felt so good with my POET shares like 2021 as this is finally the "POET year" I had been waiting for since 2014.
