I don't know why you should even ask, pump and dump tokens are not exactly the kind of project you would want to keep long term, so if you already made some profit sell without wasting much time, if not you will be the one who will lose later, better to sell and buy projects worth holding for long term.
Agreed, also with its not really good reputation project on Bitcointalk, its preferred to be sell off rather than regret it later because its dumped hard or even rug pulled.
