It is natural that online gambling companies will require KYC to prevent any kind of money laundering and they will take this step to confirm the legitimacy of the funds in your wallet. But i think it's fine not to search for personal information in very small cases. On the other hand it will be considered as the best security because when your fund is considered valid they will ensure your fund is always safe. Even if you violate their terms, you may suffer a lot. So i think key is always better if your mean amount is big. But according to your secret report you can gamble from hide.
