Manual withdrawals aren't a big problem if you don't need the money urgently. I waited 2 to 3 hours for my first withdrawal. The money arrived without any issues as USDT in Solana chain. Of course instant withdrawals would be better. Perhaps they could offer this for accounts with high wagers and top-level security. Processing all withdrawals manually also requires a lot of manpower.
I understand what you're saying, and you're right, automatic and instant withdrawals are much better and can be the solution, but you have to see how the structure they are managing internally is, a casino like spinly is constantly improving, we can't stalk them just like that, that's the solution, we don't know their internal problems, but depending on how much the money came to you, at the end of the day that's what matters, some casinos are improving little by little
I agree that if there's no urgent need and we have time to wait until we need the money, then it's not a problem at all. However, it's usually in urgent situations that people withdraw their funds, so they don't have time to wait any longer.
I think psychologically, as humans, we want things quickly; we can't deny that waiting is boring.
However, on the other hand, we can't interfere with the casino; all we can do is suggest that withdrawals be made automatically.
