Not all altcoins are waste, it seems that a few altcoins is a back up for bitcoins and use for exchange and tradings... I use my altcoins exchange to cloud mining that I got it from faucets. I can't participate regularly in exchange services due to my busy time.
But nevertheless each of their coins are used at their discretion, despite how much you extracted them from the tap. I have more than once met people who do not want to trade out for little things and concentrate their attention on more important things.
