I never knew that there are online casinos that gives out winning delayed. I thought everything online is instant, that is why most gamblers prefer gambling online than in real life. That's also one of the main reasons why online casinos are famous.
Actually there are people out there who prefer real life casinos because the payout is instant, once you decided to call it a day, just walk in the cashier to exchange your chips to fiat and its all done, unlike online casinos, if you plan to call it a day and collect your winnings, you need to cashout in BTC and send your BTC to your local exchanger to convert to fiat. But to those who loves online gambling, everyone loves to have their payment in an instant, nobody want's to wait.
