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?
It all depends on the projects in which you participated. If they are promising, just wait for the tokens to show growth. Do not despair, maybe this is a good coin, and when the market turns around you will get a good profit.
