For me those shit coins i will just make them some kind of surprise rewards if it suddenly has a value on it, but if it's not then i will just let it rest forever in my wallet, thinking about it to much would become a pain for ourself, so just let it be.
I had lots of coins that has really given me hope in the past or favored me with their value and seeing those coins rise again will give me utmost joy, not only for my benefit and for the effort of some of the developers on the projects. We have some projects before turning to shitcoins that really tried its best.
But unfortunately, the market is too big to accommodate lots of competitors and only the mighty at the moment stands, you see, some of the projects we see today that are topping list on coinmarketcap aside BTC, ETH and LTC might end up turning shitcoins too one of these days because we will have thousands of coins that will be launched in the future, so sometimes, we just need to leave the past and move along with the present.
