It is not only about the devs, it is about the community, no matter how good the project is, no matter how great the devs is it will not fly to the moon if the community will not support, in cryptocurrency, it is a power of community or many people if the project will go to the moon or not.
Everyone of course must support and have their respective roles if you want to go to the moon,
just imagine that there is a good project but the developer doesn't work optimally, of course the project will not run
