It should be beneficial for the casino to try to identify errors/problems in the operation of the website or casino software. Because the financial security and profit of the casino directly depend on this. Any sane casino will offer rewards for finding bugs for white-hat hackers and ordinary users, or even organize hackathons.
For sure before a casino is launched, there is what operators always do and that is make sure to test all the system of the casino systems to make sure they are bug-free because any casino that has a bug problem will likely not succeed in terms of revenue generations which is an integral part of the casino operation.
Some casinos even give incentives to expect bug hunters to run several private hunts on their systems before the site goes live, The majority of the casinos that crashed along the way are all doing so because of a lack of proper bug tests and exploitation of the system via the bug or other system failures.
Yes, most of the time on which these platforms are completely ready on the time that they do launch, only a few will really be having that kind of bounty program into those the public
if ever they would really be running one but its not really that something common on which they would really be making announcement if ever they would really be giving some rewards
but somehow people or users could really be able to experience some possible problems on which they might be able to encounter. So the best way to do is to report it to
support and tell them but never expect about bounty or reward not unless if it is really that a serious bug that had been found.
