I was reading your FAQ did not found any minimum withdrawals were mentioned there. If it was there then might be missed by me. As well, would like to see more competition here as well along with weekly, if can have a daily it would attract more users to play your site.
^ Probably because they removed it as what has stated in the service section on the signature campaign thread.
https://bitcointalk.org/index.php?topic=5339647.msg57081851#msg57081851There are many complaints that they had high fees upon withdrawal but now, it is good news that they remove it and I think this will also attract gamblers to visit their site. The last promotion I saw was on Games and Round bords, if there is, it would be announced here.
The fees they have removed is just for the signature campaign people I think and not for other users. So if you register and play there and not part of the signature campaign then you would have to pay the high fees this is what I have understood it. OP will clarify this and accordingly we can think about it.
