man you gave away too much game brehParlay. Lol. Or Just Bet more money. If you really think Canelo is gonna win just put more cash on the line. If you're too afraid he might lose then just don't bet and save your bread Simple
Also You could bet on a specific method of victory if you want. For example Canelo by decision is at like -130. So if you put $200 on that you'd make $142 if that's the outcome of the fight.
Or find another fight that has more favorable odds with a greater payout. You don't always have to bet on the big popular fights with the star studded coverage. I make most of my bread off of fighters who most casuals never heard of
