but unfortunately not all gamblers want to do KYC, especially gamblers who are more concerned with anonymity. they will not like or perform KYC on any site and especially gambling sites. so they prefer to look for gambling platforms that do not require filling out KYC to keep gambling.
but keep in mind that gambling platforms request KYC not for security but to verify whether the gambler is in a money laundering case or comes from a country that is prohibited by the gambling platform.
Depending on the size of your bets this could be impossible, for whales or people that like to gamble regularly this is not going to be easy and most licensed casinos will at some point ask for this information, however for the people that just gamble once in a while and do so with their spare money such a thing could be possible, especially if they prefer to gamble at several different casinos, as in that way the amount of money wagered will be even smaller and the chances of triggering some sort of flag that makes the casino to ask for this information will be even lower.
You are absolutely correct, for the high rollers, KYC verification is inevitable, its a process they must pass through as long as they are gambling on a licensed casino, except the casino is not licensed, but its simply stupid and very risky to go gambling on casinos that are not licensed all because of trying to avoid being asked to go through kyc verification...
As a high roller who has not committed any money laundering crime, or does not have any intent of doing such, and also, you are not in a region that is banned or not supported by the casino, i see no reason why the gambler should be avoiding KYC, i mean its better to pass KYC verification and have your money, than losing it in an attempt to avoid being asked for KYC verification.
Stupid decision for high rollers to avoid KYC compliance casino since this could make them more secured especially when dealing on their accounts and transactions happening there, hackers cannot easily withdraw especially with huge amount of money since for sure they will be flagged and ask for KYC for verification.
Compare to Non Kyc casino where hackers can easily take out their balance and worse the casino where they trust is a scam and they cannot withdraw their money deposited on scam casino.
