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.

If the platform is still online and the community is still active, there is a possibility of rebranding or relaunching, so its better to get updates, but if all traces are gone—platform, community and volume—then better move on and consider it as a loss; its part of being an investor in a highly volatile industry.
