First attempt at withdraw was June 19, 2015 04:39AM. 30+ hours ago. They also don't allow you to make another withdraw request while one is active. I know I've seen the comment about weekends being slow to respond so keep this in mind if you want to try playing at Betchain. Personally I don't play at Bitcoin Casinos that can't get the withdraw moving as fast as the deposits.
Just noticed that the twitter account has been used many hours after my cash out request. So someone is available...just not when money is leaving them.
