Laziness sometimes gets you and you just hold your coins hoping that they will go up in value and then you see it crashing and missing out. It's laziness, sometimes it's just easier to think that something is going to go big and go into that denial. My advice is to take it as a loss and not waste too much time still hoping that somehow they will be worth something. If they're worthless, then don't bother selling them, and just hold them on the side just in case. Understanding that mostly likely nothing will happen with them.
