Floyd Mayweather tried to bet US$400,000 just hours before fight he would beat Conor McGregor
American boxing star is now millions of dollars richer after extending his record to 50-0 but he could have picked up even more cash

How much is too much money?
Silly question, especially if your name is Floyd Mayweather. The boxer who makes Las Vegas his home has often shared images of how big his bets pay off on social media and, just before a fight against Conor McGregor that he said would bring him around US$300 million, he was so confident of his impending victory that he tried to get a little more action.
There’s no law preventing fighters from betting on themselves and, even at 40 and almost two years removed from his last fight, Mayweather was 49-0 going into Saturday night’s fight against an Ultimate Fight Championship star who had never before fought under the constraints that govern boxing. Seems like a pretty safe bet.
So, at around 3:30pm, Mayweather strode into the bookies at the M Resort with US$400,000 in cash and the itch to wager, according to ESPN.
