Sorry, did not see your questions. 

Yes, of course we will pay in the event a book can not. As a matter of fact, you would never know there was an issue with that bookmaker because the Cointeller VIP Host transfers all BTC balances from sportsbooks to Cointeller.  This process occurs 7 days week and the sportsbooks themselves are not involved with this process.  Each deposit/withdrawal a customer makes has an inverse transaction on the sporsbook's Cointeller account.  If unable to maintain a positive balance, the sportsbook will be removed from the Cointeller Network.  In this scenario, all BTC balances would be returned to a customer's Cointeller wallet. 

This guarentee is the MOST IMPORTANT part of the Cointeller product.  The moment one customer is "slow paid", or "no paid" , the Cointeller reputation is permantly broken.  Cointeller will not let one customer go unpaid.
