It is highly unlikely that various casinos will stop claiming KYC procedures. Because regulatory requirements aimed at preventing money laundering, fraud and other financial crimes are unlikely to stop it. Casinos are required to verify the identity of their patrons and ensure compliance with the law. So that it can provide complete protection against illegal activities. All of these issues are troublesome for the customer but are an essential part of the casino industry to maintain security.
It quite unfortunate that Casinos only ask if the user registering the account is up to 18 without them working on further verification process, and children below 18 can simply register without the casino even knowing. Though even some adult would prefer not to go through the process of providing a means of verification to prove that they are actually up to 18, and I believe this is among the reason why casino decided to start showing less concern for the verification process. The KYC process is really important to the casino and also and also to the society as it would also reduce the number of persons creating multiple accounts for abuse.
