Realizing how negatively kyc is seen by many players mostly in cryptocurrency casinos players am confused what kyc does in a casino, why do some casino operators have kyc and others don't have. I email also a part of kyc because most casinos often than not request email. What are KYC's advantages and disadvantages.
This question has already been answered before.
Some casinos want to build a legit and legal business.That's why they are following the rules and regulations by implementing KYC procedures.
Other casinos want to stay in the shadows,but they want to gain more customers by not having a KYC requirement(like you said,most gamblers hate KYC verification).
I don't know about KYC having any specific "advantages".I guess that the casinos complying to the rules and regulations is the only advantage of KYC.
The two main reasons why KYC was imposed are fighting money laundering and users trying to abuse the casino bonus programs,by creating multiple accounts.
