It really depends on the person who owns the altcoins as they should be the ones to decide waht to do with it since it is theirs. But I understand that trying hodl it might actually yield to a greater amount.
but it can also yields to losing,so depends on every holders prerogative.i guess what we must consider is to research to movements of your coins,if the projects seems so unresponsive so maybe ibetter to reconsider the holdings coz our funds is precious enough to bet on other coins if the first doesnt seems to profiteering
