If you find a bug on the bounty campaign will you use it to gain more coins or email the brand?
Simple! Email the brand and request to show them the bug in exchange for some of their coins as reward. However, care must be taken to not come out as greedy. It's not ethical.

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?
I think this is dependent on the brand as a brand can decide to call your bluff or agree to reward you. It depends on the manner of approach and the laid down rules of the brand. In other words,what works for brand A might not necessarily work for brand B.
