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 seems like you hope you can use that coin later. Because from the first you get coins until now the price doesn't go up and it still can't be sold. Not only you, I also experienced things like you. What I do is not look at the coin and focus on the new bounty. It's better to look for new coins sourced from good projects, hopefully they can be sold after they are received.
