KYC can be solution to prevents the money laundering and other illegal things and even for people under 18 years so those people can't playing gambling on that casino.
But is that the only thing they can do to prevent money laundering? I honestly doubt any business provider care about that, they do all of these check because the government demanded them to do so. How effective is KYC from preventing people launder their money? Why not block transactions above specific value to begin with if they don't want to risk their platform being used as a money laundering spot? Another issue is how unreliable business data protection with so many data leaks, not to mention false positive or terrible system that failed to detect individual as a non-dangrous player because one or two things like faulty image processor.
KYC verification is very important in every case. By sharing our personal information when making an account on a casino site, we cannot commit a crime like money laundering because our personal documents are submitted there. Those involved in money laundering always try to maintain their privacy in every case, in this case if any casino site asks for OIC verification before using it, then they try to avoid such casino sites. But in all cases KYC verification does not bring us anything good. Many times it is seen that we do account verification in some casinos or gambling sites where those gambling sites themselves work like money laundering, as a result of which every user of that casino may be in danger for the activities of that site. So whatever we do, we must think carefully and then do it so that later our mistakes do not become too big.
