Hello. Actually, if you play in a decentralized way (with your own EOS account) - there are no deposits or withdrawals. You bet directly from your EOS account and winnings are sent to it after the settlement of the bet.

In case you are going to Sign In with FB, Google, or Twitter account, EOS-based tokens withdrawals are instant.

BTC withdrawal deadline for both cases is 48h but in most cases, it is processed within 12h.
