I read the 2nd link provided by the OP and found several cases of not paying big amounts. Every time they are creating excuses to pay the big amounts. Some times KYC, sometimes multiple accounts etc.
If a casino is really complicant, asking for KYC for insane amounts is nothing unusual. Many see this as a crypto laundering machine, and once they are unable to withdraw without KYC then they complain that the casino is a scam.
