I'm sure everyone here still keeps dead coins in their wallets to this day because we really can't do more with dead coins in our wallets, even though there is a dex platform for coin issues, but if we look at the high fees on ethereum then it will only be a waste to sell the coins and it is better to leave the coins as they are because they will never get any development from the coin owner.
Yes.
That's for sure and there is no choice but to just keep it and if something odd happens like the price of that coin starts to increase somehow. You'll get some break even or at least recover a few loss upon selling it.
As these dead coins are good to be dead and forgotten that will eventually have them almost zero volume.
