Since a couple of days the bookmaker 18bet.com has been published its lines at betbrain.com
I looked into it and they seem to have fair odds (almost as good as pinnacle on NBA and MLB) with a very good sign-in Bonus (50% up to 100€, 6x roll-over, 1.80).
To good to be true?
I do not find any reviews with google. Has anyone made experience with them? (Espcially payout)
