Yeah... users have been complaining about not being able to withdraw money from it for over a day now... so... hrm....
The owner is the sole developer so there are sometimes technical difficulties. He does however always resolve them. If you're unable to withdraw you can contact him at
http://www.reddit.com/u/BitVegas or wait for him to log onto the server. If the server has difficulty sending the withdrawals he always does them manually.
The majority of the time, when withdrawals don't work it's just because that wallet is empty. He usually fills it up from his personal wallet within 12 hours or so.
