Casino should act fair and write up that their casino is a KYC compliant platform since if they say about that they are not but at the end they ask this when certain withdrawals has been executed then they are just telling a lie or not true to their words regarding on what they right at their thread. If they are just transparent at first for sure that they will not get questioned by anybody since many will get used to it and comply especially if they see that the casino they are playing is a good option to use since this is reputable platform.
Also gamblers should not do that actions like register immediately and then play without knowing the rules since this could put them in huge harm especially if they asked a KYC by the casino they played.
That is why I join others to advocate for the KYC at the point of registration and not at the point of the withdrawal. All this things make me to like Centralized Exchange Platform like Binance, they would asked your KYC at the beginning of the registration and once you provide everything they need and that is all. But coming to casinos we always see the opposite of it. And most number of players didn't read the ToS of the casinos they play with. They only went to register and start playing games and when they are hook up then they will start complaining, while the fault was from them. We have seen a lot of dollars have been lost because of these nonchalant attitudes.
