As we see, all crypto casinos have a KYC procedure, except casinos without license(the same time it is enough dangerous to gamble in such casino as for me). The difference is just what you have to do. As i see - all casino get your personal data, so i don`t know for what purposes we use cryptocurrencies in such casinos. It doesn`t anonymize us.
PS. Anyway the OP made nice job, thx.
It's not a requirement to deposit and play but these casinos listed will likely ask for KYC if they think your account is abusing like in the case of one complainant
After examining patterns of the bets placed on sports, and noticing signs of abuse, our team has decided to enforce an electronic KYC check on your account.
There may be some reasons like a violation of the terms and the use of VPN when the casino doesn't allow it, it's to protect the rules of the casino and to protect their players as well.
