Are you of the opinion then that all these sales at 9, 10, 11, 12 cents are just retail shareholders selling at huge losses? Opty

Sure why not... retail shareholders were able to purchase at .10 /.11 /.12 cents before... perhaps some have bailed out..... traders giving up... perhaps shareholders who rather invest in something else.... some taking big losses... others perhaps not very much...

Can Crossflo shareholders sell their PTSC stock yet?? or still restricted?

Again.. the volume right now is soo low that is probably but a handful of shareholders exiting... one main investor we all know of course...
