Agree
He doesn't know the site can use (bait-method). Small withdraw getting process, the big withdraw getting hold/blocked with some stupid situation like (KYC) or somethings. There also have some case while the casino buy some times by contacting provider, etc for not process the withdraw (accusing the provider)
The provider came to bitcointalk, clarification the bet is legit & fight againts the accusion from casino. In the end, the provider end-contract with the casino and tell to the people that the casino is not trustyworth due of the situation.
