If you are just a recreational bettor and not trying to bet off numbers, your best choices are:
Heritage
Bookmaker
Youwager
If you go a step below those, Jazz has a reduced juice skin called "Looselines" that offers -107 sides and totals
Betmania is also -108 and has some good bonuses.
All 5 of those have been in business at least 15 years
All of them accept and payout in Bitcoin. Even if BTC seems foreign, take an hour to learn how to use it, you'll be very glad you did.
