I think the problem of multiple accounts cannot really be solved that easily. What comes into my mind first and foremost is just getting someone elses or a fake ID and using that to create a account. You can also use some undetectable VPN to make it look like each account is coming from a different place.
Although that being said, a lot of VPN providers are being detected by online gambling casinos, so I guess its up to you whether or not you would want to risk it on such a scheme. I really do not see the benefits of gambling on multiple accounts. The cons outweigh the pros.
I guess, for now, the problem of multiple accounts is not a big deal for the casinos because they must have found a way to detect those multiple accounts. Even though they might be using a VPN, I guess the casino will find it and it's just a matter of time for the casino.
People shouldn't try to use a VPN if they are in countries where gambling is prohibited or their country is on the no-go list for that casino because that could create problems in the future. But we can't force it on them because they play gambling or not, it's up to them and they should understand the risks.
That's not the point, what I mean is truly and technically censorship-resistant like Bitcoin. Because the purpose of decentralization isn't decentralization in and of itself, but censorship-resistance.
Plus I'm asking, are these Web 3.0 casinos not merely centralized websites running on top of centralized data-centers/servers?
I apologize if I don't understand the point. But if it's for that, I don't know for sure but it looks like it can survive because the casino can adapt to the situation and conditions.
Web 3.0 casino itself is just getting started and I think it's still a long way to go.
I believe not always, that's why they require KYC, it's easier for them than developing a security system which smart users can go around eventually. Plus casinos without KYC can also be used as mixers/tumblers.
Hopefully, the request to fill out KYC is only used for gamblers who use a lot of money so that it doesn't burden small gamblers who don't use a lot of money. If the user uses the casino as a place to launder money, then the casino can ask or request KYC from them.
