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 is difficult to give accurate advice, you need to know what tokens you are talking about. There are promising projects whose tokens are best kept for a long time and they will grow in value. The tokens of other projects are best sold immediately at any price, because they do not have the prospect of speedy growth.
