There is no update on withdrawal fees. When you want to make a withdrawal, there is no estimate of how much you will receive or how much fee you have to pay. I have seen this since Winna was featured on the forum until now, there has been no progress on the exact fee price.
I don't have an account on this casino and for sure, we can point to one factor that have been featured on most casinos which is the withdrawal fees display on the check out page, this is where the whole game ends, but if winna casino doesn't shows such information then it has to be worked on to avoid gambler's just speculating their withdrawals fees.
Maybe one can check their terms and conditions page and find if there is any information written about withdrawal fees. Usually, the casino will show you the withdrawal fee when you go for the withdrawals but if there is no such thing, maybe they offer free withdrawals

By the way any regular active user of Winna casino can confirm this ?
