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.
Processing transactions
manualmanually may require manpower but it is cheap when you send everything in bulk than to be processing the transactions everytime a player made
aapply for withdrawal. This would require manpower and stressful for the team processing transactions
andevery minutes as users keep applying for withdrawals.
I think the Spinly team carry out a bulk withdrawal method which is easy and less expensive for the team but many users may not understand this and want to see an improvement which is not going to be easy for the team if every single withdrawal is process immediately and manually.
