My idea is that sport fans are very good target group to propose them smth a-la "special for you".
It is easier and safer to understand and communicate (in terms of nobody else but you and the shop knows your name, e-mail and address) with what you like personally than listening to broker's "everything you want, just give us the link".
It is just my own opininon, of course...
That is an interesting sentiment the way bitcoin and sports betting seem to pair together so naturally.
Is there any existing examples?
I only bet on BeatTheStreak, which is free to bet, but has only one big prize in fiat.
There's two I really use:
bitbook.biz - features accounts where you can maintain a balance and betting is comparatively easy
bitcoinsports.eu - accountless betting, a bit more challenging to track your bets, but you don't keep a running balance there.
This site's a bit different from a traditional book in that its parimutuel event betting, but I've probably the most reliable site in the long run:
BitBet.us - Number of events they carry is low, but the variety is rather large (as are the sums bet), the operators also have much more to lose in reputation needed for their other businesses as an incentive to not go rouge.
Read through the gambling forums to do a bit of research on your own though. Bitcoin betting is still a bit of a wild west and its hard to tell when an operator is going to go rogue or just suddenly close up shop. There might be better books that I've just been afraid of or not had time to try.
