What further proof would you want? I had lots of USDT + ETH in my account after a lucky streak, they refused to let me withdraw, removed all balance from my account and suspended my account. The reason? Non compliance issues but AFTER turning over 450k USDT at them and after using them more than 2 months! LOL
Plain scammers, not much to say. They were all too happy to take my deposits however.
It sounds like you had a very frustrating experience with this casino. But, without more information, it's difficult to say exactly what happened or why your account was suspended. I understand that it may be difficult for you to provide additional evidence if your account has been suspended, but maybe you could share proof of deposit and any communication you had with the casino staff. This could help us better understand what happened and why. In my experience, it's rare for a casino to suspend an account without providing any sort of explanation.
