I am not surprised at all. The reverse split was so large it reduced current holders from roughly 975m shares to 243K shares. The 17,284,000 you reference equates to 4,321 post split. Why would the remaining holders of 240K shares not have sold - why would they? The price as of this writing is 2.80 post split. This equates to a price of .0007 pre split. Very possiblle that many, if not all, of these shares are underwater. Why not let them ride? I think it is human nature. Look st how many lottery tickets are sold each week, to buyers who don't really expect to win but maybe, just maybe they might. PS Holders pre split that purchased shares at .005, and some bought much higher during the recent rise, need a price of $20 to just get their money back. I seriously doubt $2.80 excites them.
My opinions.
I am surprised only 17,284,000 pre split traded since the split,
