If you have any you more you can add don't hesitate, now is there any way to get rid of this problem? i know some will say its bounty manager's fault but now that this have happened is there any solution?
Not really.
Just because a token is listed on an exchange doesn't necessarily mean that it is 100% legitimate, as demonstrated as your discovery here. Especially when you consider the fact that these entities are largely unregulated and there is virtually no oversight on any of the activties they do, let alone bounty campaigns.
I think you just need to be more careful. Do your own due diligence, try to pick bounties which you know are from known teams, and try to pick bounties which don't have a KYC clause that can be used against you.
