There used to be 2 coins that the purpose of them was to burn dead coins. The problem was the coins had to at least have a value on the currency checking websites like coingecko or it wouldn't be accepted. The idea was to "clean up" al the dead crypto and trapped crypto in peoples wallets that will probably never see the light of day again. You were meant to exchange these for the projects native token. This is why if you holding coins you have a bad feeling about or coins that do not appear to be doing well or have no use. Rather sell them and make something then keep them forever and make nothing.
Once I spot a coin in my possession which belongs to a project with zero progress, even if I got the coin via airdrop, I don't hesitate to dump. The problem is that, most of such Shitcoins never get listed or have very poor trading volume even if they are listed officially or unofficially on DEX mostly which permit that. I have a few in my possession, I already counted as loss.
