Back to my ethereum wallet, each time I see those worthless token I just laugh and continue with what I login my wallet to do. If you ask me why I'm still holding does tokens in my wallet I can't give a reply. Why are you still holding those
Sometimes its best we still keep holding and follow it till the end since the market is so full of uncertainties and like you said, it is not that the coin you are holding doesn’t have a project or the developers have given up, just that the competition in altcoins market is just way too much and that is why many of these coins are not growing because many of the new investors that ought to have invested in it are exposed to various option, this is why a project with products will always be the best, at this time of bear market is when their product should speak for them.
