i think on fortunejack there is no withdraw fee ?
But sadly the most other casinos where iam playing have fixxed fees like 0.001 XD
Which casinos charges fees that high? Most casinos that I know charges fees lower than
BTC.001
The gambling site I tried so far is windice. Their trasaction fee for every payout is at .0009+ which is very reasonable for me because my money got already transferred to my wallet just few minutes after. I don't know to your perspective if it's really good since I haven't tried other sites for comparison but I'm definitely satisfied with their service

Ps: I'm not shilling.
