Based on my personal opinion only, you can try the following gambling sites.
1- sportsbet
2- stake
3 - duelbets
4- rollbit
5- roobet
6- bk8
I ranked it based on my experience, and as you can see sportsbet gives me the best exprienced.
From all your list above have any gambling platform site without passing KYC? I worry with my document upload on several gambling site depending with identity is most prohibited document. All site above ever with Stake only and 5 site from sportbet, duelbets, rollbit, roobet and bk8 still new and not active or have account there. I think most important to know with term of service each casino site before active playing, actually have several casino need trough KYC when withdrawing assets although withdrawing support with cryptocurrency only without have option by fiat.
As far i know KYC requirement is a very common issue to sign up any gaming platform. The authority of the game sites also does not want one of their clients to fall down in trouble. They store KYC securely. However, nowadays there are more sites in gaming platform in which no need to pass KYC. One of them is Bet furry, Bitgame and according to me both are the best online gaming platform.
