Stake, BC.Games, Coins.Game, I think I can include Freebitcoin (they have some betting market), and there are some other good & old casinos that will not ask for KYC just like that. I had many deposits/withdrawals, so I can say that I trust them with my money and I am active in these casinos.
But I don't like when casinos have mandatory KYC rules and I am not playing in those casinos. Roobet is a good example, I remember when they introduced that rule, I withdrew my funds before that and I never opened their site again.
Sooner or later we may see that all casinos will have mandatory KYC, so actually we cant guarantee that those casinos where we play now without KYC will keep the rule as they may implement mandatory KYC in the future. Once it happen there are only 2 options for us, follow the rule or leave the casino because we do not want to undergo KYC. I'm in the position as you who dont like mandatory KYC, now I become more selective in registering an account in new casinos.
