The only circumstance a purchase of PXYN is advisable is during a severe, heavy volume sell off, for a day or swing trade at most.
The last time (only time) PXYN capitulated was when it broke down to .0071, at which point I gobbled shares up to .01 and flipped it back 10 minutes later for over 60%.

My reasoning is 1) the company will not survive 2) there is zero sponsorship for the stock, not even by management and 3) the relentless, never ending DUMPING by the Convertible Preferred will not stop until an appx 7-800M more shares are liquidated.
Even at that point, Id expect additional preferred to be issued and the dumping to start over again coupled with a reverse split
