Casinos that charge the highest withdrawal fees:1. BetHash - 0.002 BTC:

2. BitDouble - 0.001 BTC:
3. Cloudbet - 0.00054240 BTC:

4. Fairlay - 0.00043 BTC:

I am surprised by these casinos with high withdrawal fees. What are these numbers related to? Is it really only with simple greed and the desire to keep the money of their users on their site, so that they subsequently lose them? Free - $85 is a huge range of commissions.
Yes, I see that the prices in BTC are indicated. These casinos could not put floating prices depending on the rate of BTC?
