Do Established Casinos protect our KYC better than the New Ones?

I have some doubts on that. I dont think there is a real difference between new and old casinos.

Both new and old could rely on third part or just having a strong standard operating procedure for storage of these precious data.
If players doesn't want complete a KYC there are tons of options for gambling with crypto and Bitcoin.
However (my 2 satoshi) i would prefer to stick on local rules and avoid issues on this matter...

New casinos can offer modern security but may not have the long-term track record to prove it.
The safest approach is to judge each casino by how transparent they are, how they handle past security incidents, and whether they use strong, verifiable security practices. Whether old or new, no platform should be trusted blindly, especially when it involves KYC documents.

You don't know certainly which casino takes care of your personal information more securely but the past is a good indicator of the future, so if there is a well-established casino that has never had a problem with keeping users' data secure, then for maximum safety, it's better to stick with that casino instead of newer platforms. Btw as I said, in theory, this doesn't mean that new casinos don't have a better data security and management. It depends on you, if you want, you can risk and try a new casino, everyone was new after all and gained reputation over time but if you are extra cautious, then it's better to stick with old ones.

Some platforms claim that their use KYC data are properly protect but I don't believe it because they contract third party to handle the KYC and they cannot guaranty that the data will be protected. But I agree with you, most reputable casinos that ask for KYC also try to protect user data so they don't make mistake that will lead to litigation. We can then say that the reputation of a casino have correlation to their ability to maintain confidentiality.
