Howdy,
The NFL season is finally here and we have great FREE offer for all existing players to kick off the season - NFL is American Football for those of you that do not know!
Respond to this email with your Betballer username and we will credit your account with 10mBTC.
This 10mBTC must be placed, as one bet, on any NFL market we offer at odds of over 1.80/-125. If the bet wins, you keep the PROFIT from the bet.
The funds will only be credited to accounts that have registered up to and including today.
Good luck! Team Betballer
