Well, I think so. Since the rise from the 20 cent range, it is normal for the shorter to bet against a further rise!
They probably set the 50 cent barrier as "the last line of defense" on the way to $ 1.
I've been looking very closely at trading for 2 weeks. Look at the wall @0.49!
Normal shareholders don't sell with these great prospects after all those long years of waiting but not before reaching the finish line!

or is there someone here who currently sell?
Don't be afraid for your " coming out".... lol
