They charge 0.00025btc, but what purpose? you also have to realise that.
I can say about freebitcoin, they cost a little higher fee when you make a withdrawal request but you can't blame them for that. all of those fees they use to boost your transactions.
How could you give them blame when they didn't take anything to their pocket! ~
Freebitco withdrawal fee is reasonable. They have dynamic withdrawal fees and they don't charge anything high. Currently they are charging less than 800 satoshi for instant withdrawals. ‘Pmalek’ has mentioned about 3 types of withdrawal fees. ‘No fee for withdrawal’ is always attractive. And I prefer the dynamic one too. But most of the casino sets pretty high amount as fixed withdrawal fee. There is a little explanation behind it. Few casino sends withdrawal from their hot wallet. And they have to pay fees to accumulate individual users deposits into their hot wallet. For this reason they charge extra amount from user withdrawals.
