I feel you!!! we are totally dealing with the same dilemma. I have been holding 5 kinds of altcoin that doesn't worth that much even if i sell them all.
so what i choose to do at the end is that, i hold all of my alt coin, and i don't know for how long i'm going to hold it.
But I have a pretty good reason to do so, it is because if i sell it, it won't make me rich because it does not worth that much. But if i hold them all than i get to face 2 possibility, it might make me rich if the price rising but it won't make me poor even if its price falls down.
