Taking Advantage of BetEd's 1st Bet bonus help

[heyyo2]

I see that they give you a 50 percent addition into your win on your 1st bet if only you win and the maximum is 250 dollars.

So say you bet on a game that definitely will have a winner which would mean the line will be -4.5 or 5.5 so there will be no push. If you bet on a team and risked 550 to win 500 on Beted... you actually win 750.

I was wondering what is the max amount i can bet on another book to hedge this bet for a guaranteed profit. I was thinking aroun 625 or so on another book?

Is this illegal to do? I also heard someone said BetEd took someones entire balanace because that person made a bet on a FRIENDS computer which does not make any sense. That gives me some bad vibes about Beted but their additional points for underdogs makes it look real goood.

Thanks.
