You can stay however long you want till it reaches zero but don’t preach others to get out. It’s none of your business. Most of the people invest with proper DD but when investment goes down continuously for half decade or more with zero sales ( recurring revenue) and full of missed milestones , you can’t blame being more critical. Every competitor always seem to be one step ahead of in commercialization . Heck we are not even current with filings ( basic requirement even for a penny company) what gives you so confidence or comfort unless you are a paid pumper or supporter? Of course it’s not that I don’t believe in the company I still believe there is a chance to succeed with all the new developments. But 1+ cent after all these years is beyond disappointment.
