I think they are aware that people don't like KYC.
But if they can't do something with that then that's it, nothing to do with that. And those players that want to use them continuing with the KYC process is/are aware of the rule that they are implementing.
No idea about the last question because haven't tried them. They have free play tickets, you can try.
I think they answered it already and they don't require KYC to their players.
What I'm concerned about is their 0.001 BTC minimum bet, which is a huge amount for a single bet unlike crash game where you can bet at least 100 sats.
This Binary option like a crash game to me but the difference is that the crash game is randomize and Binary is by exchange price.
