Where are you? I think you have said Canada. I’m in Ontario.
Betway has the most MMA Organizations and has live betting many times for it, but their live betting isn’t nearly as good as bet365. Ive been semi limited on it for a while, but it is very inconsistent. It will let me get decent sized bets (for me) most of the time, but stopped allowing me to cash out quite quickly.
My books in order of familiarity and use:
1. Bet365 - I think it is far and away the best except when it limits you.
2. Betway - many different mma organizations and has more types of prop bets. Odds are not typically great.
3. BetMGM - Getting used to it. It has let me do a $1,000 bet (that was my biggest ever - it was on Clarissa Shields Moneyline)
4. DraftKings - Getting used to it, but I find on live boxing their odds seem to remain the same for longer than Bet365 which I find to be an edge. This is the only place I was able to find the Road to UFC bet that you suggested last week at +250. It let me put two bets of $125 each in it (thanks again for that).
I am also interested in who has live betting for boxing with live props (like bet365) and offers many fights (like bet365).
