It really depends on the person if he/she prefer sports betting rather than casino. KYC is not important for gamblers and I would say that KYC is rather important for the site which is implemented to less the chance of someone laundering money using the site where in my opinion that a gambler able to launder money means that the site doesn't have strict rules or whatsoever that can prevent a person from doing illegal stuff. Good luck from Nakamura12, Ciao.
At least if we have to provide KYC, the casinos better invent sth pleasant to do with it, for example do some little bonuses for birthdays

And also it would be an interesting idea to create gift vouchers for friends.
