To answer your questions generally speaking it is not harder nor impossible to short any stock let alone a now compromised stock like BPTH. To my knowledge the only place that at the very least slows down the shorting and massive speculative trading is the OTC.
On a different topic related to BPTH unless a miracle happens with the clinical results AND these trials move at a MUCH faster pace AND with excellent results the institutional investors will think twice about buying again shares when a potential future reverse stock split can occur should this company decide on it.....nothing surprises me at this point. PN-DM & Co. are a role model of how NOT to run a biotech.
It already a SLAP ON THE FACE of particularly original investors and long investors that believed in this company but unfortunately came too late to realize how bad the founding board members were running this business.
