Deposit times vary based on the Ethereum network load, but normally they are processed instantly or within half an hour. Withdrawals can be delayed during peak traffic times, so plan your activity accordingly. Of course, if you encounter any problems with your withdrawal (for example, the Ethereum network is under a DDOS attack and your transaction is taking longer than usual) or find that you do not have enough funds in your balance to cover the deposit fee, casinos usually reserve the right to extend the time limit.
