Not really. You can look up similar cases and any lawyer is going to advise you not to take any kind of compensation in any form (gift cards, items, balances, whatever). I think you can find some information in certain subreddits if you don't feel like reading verdicts.
Yet for some reason people still do, but then again they do and they still somehow win. Wonder why that is. Maybe because the legal ramifications in which the problem at hand clearly outweighed the compensation that was received. Idk guess some people look at things many ways and some people look at things like there's no way at all. Just depends how they respond to the lies they just tried to spread about how I procured those winnings.
If you think that you can win, then nobody is preventing you from suing them. A 'might-be-right-might-be-wrong' case on this forum (depending on who sees the case and how) won't bring you back any money.
If you take a compensation (in this case a bug bounty), you are legally entitled to nothing.
This is my
current opinion on bugs and compensations and we can leave it at that.
