I have bought over 100,000 between .50 and .70.
If your not in yet I would scale in 4 different times,for example,1000 at .60,1000 at .58,1000 at .61,1000 at .55.... if no news and your lucky,can't tell size of bids around .55 but there are a bunch,me included.
I will buy a few more times,one at bid if I'm lucky and news takes another 2 weeks and one or two at assk at crucial resistance points if need be but it could go 2x or 4x.
We were at 1.80 with a PR of revs to be 20 Million,[later scaled back to be half that]now were looking at 44 Million plus and it will be in writing.
