First point, looks like there are approx 8M $0.52 warrants remaining. More than half of those 8M warrants are held by a small number of Canadian investors who do not need to sell stock to exercise the warrants. They will put up the cash.

I wonder if the warrant holders who were using them to short at will have closed their positions to put an end to the malfeasance. Hopefully none of this "small number of Canadian investors" are part of that group.
