I'm about to dump my 700,000 shares ,someone pleas

I'm about to dump my 700,000 shares ,someone please talk me out of it. All these fluff pr's announcing "the next piece of the puzzle" haven't done anything for the share price. If this company really was as promising as I thought it was ,wouldn't others be investing in it? The MM manipulation reasoning just can't be the explanation ,and why would insiders be dumping 100's of millions of .0001 shares if this was about to explode?Either they're making the dumbest business move ever ,or the smartest. Gonna wait til the end of the day ,but I've got a dreadful feeling about what's going on and don't want to have done all this to get nothing out of it. Thanks for any replies (if anyone is still on here)
