If you find a bug on the bounty campaign will you use it to gain more coins or email the brand?
Also, it is not said by the brand that rewards will be given for finding the bug. Will they still give reward if you email them about the bug?
They will promote honesty and respect you about it. However, if there are issues in the bounty campaign, help them overcome it. As for the rewards, I think it will be fixed when it is sent to the devs team. If you email them, after the token is distributed. That is a difficult problem to solve. Or normally, when the bounty ends there will be time for your complaint. When you miss it. That would be another story.
