Even if the casino is good I don't think I will sign up I will have to check the terms of service of the casino why they are asking this information and if they ask KYC to all their members, Crypto casinos follow and adhere to anonymity and they only ask for KYC if the account is abusing, so far all the casino I sign up only ask for usernames and emails no basic information.
I salute your decision. But casinos/gambling site should take KYC to avoid abusing their system. Either that is for privacy or for abuse any of their system eg: bonus, referral, fraud or something like that. Hope, you will be agreed with this argument.
KYC can be asked if they see something suspicious on your account and that’s on ToS on most of the gambling site but requiring it in the first place is not a good one though. 5BTC bonus is quiet big for me, and too risky for a big players since this site has a few review so far. I wont sign up as well, KYC is very important to me and its too early for me to try this site.
