Based on the Sportsbet.io contest here on bitcointalk, most people are picking Barrios to win.
I can't find this match on stake, I'm sad that even if I want to bet for Pacquiao on this match, I cannot. I think many doesn't believe in Pacquiao anymore because he has aged already. But I still think that he's got that power in speed although might be slower nowadays. We'll see if the younger caliber is going to win against him or it's still the pride that Pacman has got in winning this fight.
