What i check first before is decide whether or not to olay on any site to see if the casino is reputable enough to handle my KYC data and keep them private, even though we can guarantee that but we can at least be careful about the kind of casino we lodge our details on as long as it not safe then not need to play there.
No matter how much reputed the casino is they can't guarantee that any of the details given by their customers will not be exposed because we all knew that anything that's uploaded into the internet is vulnerable to hack so when we are ready for KYC compliance then we also have to be ready with the consequences as well. But with the reputed names we can feel that they will have better security in their platform where the attacks from hackers can't do anything. All we can do is hope like no such thing will happen to the website where we completed KYC and it's also important to stick platforms which asks basic details for KYC not too much.
