Regulated casinos doesn't necessarily mean they won't turn as scam, as time goes by. Because even the casino is regulated and licensed, there are some cases that they turned as shady and eventually scam. Therefore it's still best to choose the casino to play in since you're going to risk your hard-earned money just to gamble. Anyway, nowadays, a casino asking for kyc is not isolated anymore. Thus, expect that you'll be asked of kyc if you're playing on a regulated casino.
Yea, that a casino is regulated doesn't give full assurance or guarantee, but there are some casinos that have been operating for so many years and have not recorded any bad activity related to scam during their year of their services. Those high reputable casinos are the kinds of casinos a gambler should trust while making a choice for the casino to gamble at. We have some old, reputable casinos on this forum, and they undoubtedly have good records, despite the fact that they also ask for KYC.
