I want to emphasize that I am not accusing Bitcasino.io of any involvement in the loss of my 88 ETH. I'm sharing this experience to highlight the need for better security practices and more empathetic customer support in such situations.
From your whole narration, it is already an accusing casino because you said, it is only you and Bitcasino.io knows the 114 ETH in the account and after 10 minutes of withdrawal of 26 ETH, the remaining 88 ETH disappeared. This is not indirect accusation but direct accusation. Well I will say you even have luck because they would have wipe your account and told you that it was hacked. And thank for bringing this to the forum to inform others.
