Before accepting the term of service of the casino we must first of all be willing to hand out our documents for verifications because this is the most important stage that always gets gamblers stock at some point if they don't understand what really is happening.
Maybe that only applies to big gamblers so far, as a small gambler, I don't need to send any identification, just do level 1 verification, filling in the information data is more than enough, I can still withdraw money without having to be asked to send documentation for level 2, every KYC there is always a level. That's why gamblers who have a lot of money should read the rules first before making a large deposit.
Usually people like that never know how the online casino system works where there are rules and requirements that must be read regarding KYC so most of them make large deposits and bets until they end up confused when the casino asks the user to provide their identity and complete their KYC. My suggestion is that rich users should complete their KYC at the beginning
