Betting on Mcgregor pays out x5. But is he even underdog? My first sport bet.

Hey I was kinda shocked when i saw that betting on Mcgregor pays out x5 so I decided to place a bet on Conor winning. I even placed a bet for a KO in the first minute because we might see an Aldo 2.0. Is everybody on Steem for Mayweather? Honestly I don't think he can win.

-mcgregor in the prime of his life and career.
-mayweather forty years old and idle for over a year.
-mcgregor looks like he's putting effort into his training
-mayweather doesn't look like he's putting effort into his training.
-conor 4 pounds heavier
-conor taller/more reach.
-mayweather literally says he's only back for the money.

Hope you all enjoy the fight.
