While process time of withdrawal is an important factor for most of the users. But if a user enjoys to stick around, there is no need for them to get bored and can wait patiently. A casino that's been of great service and use to the users will make them stay for as long as they can. And to me, the process and wait is tolerable and that's why it's no feat and problem for me.
Most people can not wait patiently if it is related to the withdrawal process. They want an automation process that will send their money to their wallet. Perhaps that can be done if the money is not too big but if that is too big, the casino may need to do verification and many people fail to verify themselves. This makes them difficult to accept because they will complain to the casino and the accusations start.
