It happens very rare when someone can actually find and report a bug, and I think the rewards for that should be big. In my opinion, it should be like an additional game on the platform: finding and reporting a bug. But again, I think it would be less often than once in a year, if ever, when a bug worth reporting is found.
Front end or UI bugs maybe isn't get a big rewards, if we wants to found a critical bugs we need to be a programmers or like a white hacker.
Even reports of the front end bugs should be rewarded, but, I agree, it's not something critical so the reward can be small, like $10 maybe.
Since our money under casino provider accounts, they are easy to freeze our money if we are take advantages with that bug. Because take edvantage of it was like a cheating activity, I believe we will hard to withdraw our money after it happens..
If someone left their house open, and someone goes inside and steal something, it's stealing. Taking advantage of a bug to make money and trying withdraw it is an attempt of stealing, no doubt about that.
