There are plenty of replies and questions, so I will try to read and address them one at a time.
Did JacksClub.io started charging withdrawal fees? I thought they were free.
Yes, they now charge withdrawal fees as shown in the table in OP.
You can also add Gamdom.com since it was free the last time I checked.
I overlooked Gamdom, thanks for the tip. I will take a look at what they offer and update it in the table.
Other casinos that doesn't charged but it's limited and users must meet conditions in some cases,
1. NitrogenSports - once per week
2. OneHash - once per week
I didn't want to include NitrogenSports due to their negative ratings by members of this forum. OneHash is on the list.
Acedbets should be removed from this list because they are totally unreliable and there are many issues with people unable to withdraw anything from their website.
They are no longer active in bitcointalk forum and they don't reply to messages and questions about anything.
I wasn't aware of that. I checked their trust rating, and all they have is a neutral rating mentioning problems with withdrawals. I wonder why they aren't negatively rated if it's a serious problem. Does anyone else feel that Acedbets doesn't belong on the list and should be removed?
1) Are the information up to date?
All the numbers were taken from the withdrawal or payment pages of each individual casino or based on the info given by customer care representatives. If the info on the sites and that provided by customer support is wrong, so is the data in the table.
2) Why would it be free to withdraw fund from a casino when an exchange site don't even do that?
It's one way to incentivize more players to play there. The casinos profit plenty from players who lose every day so they can afford to cover the cost of withdrawals.
@Pmalek, since you add "adjustable" on roobet then you should also add it on duelbits since I believe that duelbits withdrawal fee is also depending on network congestion but I have to admit that the fee is still higher than most other casinos.
The fee changes constantly, but there is a difference between the two casinos you mentioned. Roobet allows the player to select the fees himself. They have a few options like slow, normal, and quick confirmation times. Duelbits doesn't have that. They only have one dynamic fee that changes depending on the state of the mempool. Hence the difference in the wording in my table.
I will check and address the other questions a bit later.
Thanks!
