Both parties the player and the casino can agree to do a mediation through third-party/parties. but do you think it has bad consequences if the third party proves the player is right in establishing his identity, then the casino's KYC is not reliable?
If the third-party proved that the casino is right but the player swore that he submit all the documents and is willing to do the extra mile to establish his identity, can we conclude that Casino's KYC procedure is different and we have the right to know how and what system they are using to decline our submission because we can be the next to suffer from this Casinos' KYC system?
This is my opinion about online casinos and the KYC process, why would you want to verify a Bitcoin player when cashing out when the entire point of playing in crypto is privacy. I think this is almost against the rules of using bitcoin option for gambling. And I know that I am not alone in this . Don't you think so? One encounter I had with a casino is that after I had requested my withdrawal of funds, it was then I was informed that my account was not verified even though I had my uploaded his driver's license, utility bill and a picture with ID upon signing up. When I contacted Live support on chat to inquire further and the agent informed him that one of his colleagues will call him shortly to confirm his identity. I honestly see no reason for this when my payment method of choice was Bitcoin. After the call, my account was verified and I withdrawal was successful. It was terribly frustrating.
Casinos would love to go back to that system, but governments are pressuring them to comply with their laws, now a small casino may be able to get away with this for a time, but as it gets more popular and the amount of money moving in that casino increased then the government will make them to comply with threats of jail time if they do not, so instead of closing the casino as it would be the right thing to do, they decide to comply as the money is too good for them to give it up at the time.
