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
Yes most of those that are asked for kyc is those big bag holders and that os part of the anti money laundering laws which some time are effective in making it hard for corrupt politicians and criminals to use gambling sites as a mix for their stolen funds, mostly at a time we have to look in the direction of that, so the casino is always on the lookout for any possible loopholes that is why their place minimum $5,000 one time deposits or withdrawal on none KYC gamblers but any amount above that $5,000+ it may require the account to go through verification, so for sure a lot has to do with why casino act the way they do and what the reason for kyx demands is because in most cases, the gamblers are the one that has failed to follow the terms and conditions of the casino.
Unless for scam casinos who may deliberately lock a person out and for some reason to scam the gambler such as in cases with 1xbits unless that, if not KYC is a prerequisite for higher wagerers.
