What can be done? Do you need to do something with them? There is nothing that can be done with these coins. I made a worthless coin / rubbish coin as a collection because I thought it was very good, because there is a possibility that a coin that is not worth the future will have a high price. Let the coins be stored neatly in our wallet.
I think that today we have such circumstances in the cryptocurrency market, that no one else would act. Only long-term storage of our assets. May continue to bring us a good profit, and not lose today what we value. Although it is very difficult to determine the current trend and market correction, since many projects may not survive what is happening.
