Sportsbetting.ag Big Money Only...wtf

So I had a buddy lay some bets for me this weekend just for fun.  I started with 50 and won the SF, ATL, and NE game and am at 190.  He looked to withdraw the money and the least you can withdraw from that site is 500 bucks!? This seems ridiculous. Does anyone else use sportsbetting.ag and have this issue too?
p.s. My buddy must really suck at gambling because he has been using this site all season and just realized the least you can withdraw is 500 lol 

tell your buddy don't worry they will paid you. they know in the long run most gambler will lose, that how they run the business.
