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. 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..
It is better to join bug bounties rather than using these bugs for our advantage, especially used cheats by many players can be easily detectable by system admins and they will surely find out what causes this. I mostly prefer to report such bugs or critical errors to the support team and they sometimes send small rewards depending on the level.
