This is what I think is being used whenever I withdraw. It takes time, but I am not in a hurry, and that's okay. This ensures that Spinly is able to approve the withdrawal requests that are fine and clean. Having that said, being able to wait could be tiring for those who are not used to it but with the withdrawal fee that's low and just a few cents, that's a big savings not just for me but also for Spinly.
Your defense is understandable but as much as the manual processing of withdrawal doesn't meet emergency needs it could be challenging for both the casino and the gamblers. There are gamblers that may not continue to use the platform after discovering the long delays in withdrawal process when they compare it to other gambling platforms they have once used with fast withdrawals in no time. I think it would be nice if Spinly could try and improve on the timeframe for withdrawal it still wouldn't stop them from granting clean withdrawal requests. Just MHO.
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.
