I have a few coins I earned from doing bounty campaigns last year and they're pretty much useless since its worth is only like less than a dollar. I don't wanna just dump it because I worked hard for it but I can't exactly sell/trade it either.
So my question is, is there anyway I can still make use of these coins?
Sorry, I do not understand your question. You do not want to sell them but you want advice? What can you do with them, I think there is nothing if you do not want to sell them and invest in other coins. If these projects have a platform where can you increase the number of your coins?
