I'm not saying it can't or isn't being done but my brother has been trying to sell a million shares at .0002 GTC for the past 3 weeks and his order hasn't filled. He's got over 100 million shares so he's not really trying to flip them so-to-speak he claims he's just testing it out to see if it can be done.
Personally my shares are locked up and I have no interest in parting with any of them until this stock is roaring; hopefully to 2016 levels and beyond.
