You're all right, why would you provide your personal and private informations to someone and expect things to be alright when they gave those informations stored on their personal centralized system and they can make use of it anything we are less aware to tackle us, in this instance i will only made a suggestion that gambler should always go in for a casino that has no KYC requirements when they are gambling provided they are privacy consciouss.
That's why it's important to determine first the credibility of the casino that you will submit your KYC information. Most of the centralised casino doesn't stored KYC on their own system since they hire 3rd party KYC services to collect and verify all the data. A casino usually not allowed to hold the KYC information by themselves if they don't have license to do it even if they are a gambling license. KYC requires another license in able for a casino to handle it by themselves.
It can be found if we can look for it carefully because with so many casinos nowadays, not all casinos will allow gamblers not to do KYC. Casinos today are different than they were a few years ago, and with government interference, they have to keep up if they want to continue doing business. And if we have found a casino that really can be trusted, we should also be able to be calm about doing KYC because the casino will try to protect the important data of its customers.
