In such a scenario, what would you do? Keep "holding" until the coin comes back to life (revival/relaunch)? Erase all of your wallet data (private keys, seeds) and forget about everything (burn)? Or simply give it all away to someone else?
Your input would be greatly appreciated. Thank you.

It is a situation that most old hodlers have had or would have had. So it is not strange. Well I don't believe that it is good to delete all about a coin or shitcoin because the value has gone low irredeemable because another developer might take it up and restrategize on it, change the name etc. I would delete a shitcoin if the exchanges that has listed them also have deleted the coin. I think I have once experienced such with a coin and it got deleted in then coin exchange.
