Actually crypto always has a way of shocking people and one that springs to mind is Dogecoin. It was practically a joke for years with no actual use case and scarcely any development but nevertheless it came back from the dead owing to community enthusiasm and Elon’s tweets. Same with projects like Ethereum Classic and even Verge they was struck hard but found methods to stay alive. You’re right though others like LUNA and FTT are definitely too far gone reputation wise also in crypto never say never but some stains are just too deep to remove.
