One of the old coins that I hodl is Minexcoin (MNX), I know the developer is no longer active, but if I sell cheap now then what for, I'd better keep it until it becomes trash.
You can sell it for cheaper and then make money on the DeFi hype that is going around for a while now and when you have made enough money then again buyback MNX if you feel so, just what these coins are doing in your wallet, sitting and waiting for them to die isn't going to solve your problem, you can become hyperactive and can actually do something about it rather than doing nothing.
Me myself was having a lot of tokens in my waves wallet along with a few waves as well. I also sold all my coins and is planning to invest in some other projects that are running right now.
