Casinos existed without the need for KYC's until the government made it a requirement, and they started demanding it. IMO If the government no longer requires casinos to do KYC verification for new gamblers, casinos will go ahead and still do KYC verifications because they have seen the benefits of knowing their customers better than when they just allowed people to come onto their platform and gamble without their knowledge of who they were. What do you think? Do you think some casino's will revert back to non-KYC and allow money launderers, plus other fraudulent people have their easy way with them as a way to attract customers, or since they recognize the personal benefits of KYC to their casino, will continue demanding it even if it affects their customers?
that day will only come when the government fight against decentralized systems ends and of cause, I don't think it will. Kyc before now was a thing of choice on most online platforms or casino to be precise. Users loved to protect their privacy and identity and thus stayed away from any means of verifications that would expose their identity. Though privacy and anonymity was an advantage of the non kyc, but then every good side has a bad side.
We heard of stories how criminals used casinos to steal funds with no trace. They make deposits to their casino accounts and since there was no identification, they can go scout free without being caught. Government got tired of all these and thus verifications were imposed on these non kyc casino. So I don't see the casino stoping the kyc verification anytime soon as the government are still trying to fight against decentralized systems.
