Does anyone know of a company that sells Bitcoin odds feeds?
If you meant by comparing the odds of different bitcoin sportsbook on the same match like the nba then go visit
bitedge they offer this service for free but they only cover a few sportsbook. If you want to bet with lesser juice go to a betting exchange like fairlay.
If I'm not mistaken, is he looking for an odds to do sports arbitrage? If not, I believe that odds comparison is not important anymore because it's easy to find a site that offers great odds. There is a competitive market in sports betting nowadays hence sportsbook always consider giving a competitive odds to attract sports bettors like us.
I guess that is what he wants to do. I believe there have been plenty of services that are offering sports arbitrage betting on their sites and you get information on what to bet and how much you will bet. Though be careful with sports arbitrage, there have been instances that sports books lock the accounts of people doing this as there are more sports books that are against this than the ones that allows it.
