betting on the fights

is there any legit online places to place bets or is it just a pain the ass?

The great state of Nevada sir. Take your pick.

Sportsbook and 5dimes seem to be the last legit out there, from what I heard.

i don't even know if there's anything worth betting on in this event.

IMO the best odds are against one of the 4 horse faces of mma.
