So all in all, roobet is limiting themselves on people who are fine with it and also like their website all at the same time. This is still allowing them to make a good chunk of money as we have seen, just not as much as they possibly could.
I think Roobet is more leaning to follow authorities rules with implementing KYC than getting more profit from Non-KYC lover. They don't want any headaches in the future so they rather implement it early on and besides those who trust Roobet will have no problem with KYC implementation. They maybe missing out on those kind of gambler(non-kyc lover) but it is better to be safe from any future problems.
I think that all crypto casinos will gradually switch to identity verification. All casinos that work with fiat money already work this way. If you are asked to submit a photo for KYC, draw a watermark on your image. This will help protect your data from fraudsters.
