A run-up to over $3 again? It could happen. But, my observation of many of these biowreck scams is that only lower highs are ever consecutively achieved, 100% of the time. And I'm talking about companies run by more youthful and skillful con men who had put far more energy into promoting their thing, than Seymour could ever be capable of conjuring up on a triple-dose of Geritol.
Many who got sucker-punched by buying into the last pump-up of NNVC will be looking to get out, thus creating a lower ceiling.
Getting out with some fraction of what you've invested is better infinitely better than losing everything. There's only a small chance a tired old con man who doesn't give a shit about stock price might try to run it up one more time before all the money is milked, and he can finally retire. There's an even smaller chance he'd be successful if he found the motivation to try.
