It's not OK to use the word free. We all worked for it and we deserve something in return.
What I do is I sell half of my reward i.e if I'm not in need of cash urgently.
And then when that bounty token worth nothing that will be the same as the hunter was wasting all of his efforts. I have seen so many people have been getting the same situation like that. That's why just try to sell it when it worth something will be a good decision.
