Well, what I believe is that if a coin is sleeping, then the team behind the project are the one to be blamed, because there cannot be a working project with great potentials that is not being used by people in the crypto space, so if people abandon a project, then it just mean the project has nothing to offer to them, so the my advice to the team is to make sure they work faster and bring the project back to life before it dies finally and then I don't think anyone would be able to save it because every would have forgotten it exist.
