I deposited .64 btc with Jetwin a few days ago.  I only made 1 small bet  and tried to withdraw my .64 btc .  I was met with a message that says unable to withdraw, user is not active.  Here is Jetwin's reponse to my ticket:

So Jetwin straight up stole my BTC.  I would not use this site anymore.  Betters beware.  I have done nothing wrong, only thing I did was deposit btc and make some tennis bets.
