And it's not gambling sites who want to know their customers, it's the authorities that regulate them. Also, don't you agree that money laundering and gambling by minors should be prevented? That is what KYC on gambling sites for.
Yes, unfortunately, I agree. I think that sooner or later (it can happen in several years) all the regulated casinos will prohibit withdrawing money if you're not KYC verified. We are still far from really widespread use of cryptocurrencies in the gambling world. With the changing legislation and ongoing legislative campaigns, new rules will likely appear that will require cryptocurrency platforms to register as casinos or bookmakers. But for now, there are still plenty of sites on the Internet that don't require mandatory KYC and which support anonymous gambling. I myself don't like the idea that my personal information is in the hands of some authority. They could connect your personal data to your gambling activities which indeed shouldn't be publicized. And I believe that this is not just my opinion. We'll just have to wait and see how things develop.
