This sound like you're advertising more than anything else. Why would a crypto casino go through the banking system to process crypto withdrawals? I also don't see why would any custodial service take more than 24 hours to process withdrawals, regardless of the coin being used unless they don't have the funds in their reserves.
Have same thoughts about his intention on why he post such thing, since looking at this thread it seems that he's explaining the features of that casino. This is why it leave some thoughts that there's another suspicious actions happening here.
But OP need to answer those replies in this thread to clarify that he is not shilling that casino.
Then clear up his intention that he just want to ask question because he's confused. If OP is legitimate much better for him to search a legitimate casino which have Ann threads here and don't gamble on random casinos they find online.
