No one bets on sports and brags about their winnings quite like Floyd Mayweather, who has earned more than a quarter of a million dollars betting on the Golden State Warriors in the last nine days.

Mayweather posted a few of his bets on Instagram, and before Game 1 of the NBA Finals he placed a $70,000 bet on the Warriors to outscore the Cavaliers by more than three points in the first half. Golden State held a 52-43 advantage at halftime, which won Mayweather just over $60,000.

Mayweather doesn't publicize his bets quite as often as he used to, but he's a prolific gambler. He made more than $4.3 million according to betting slips he shared on Instagram and Twitter in 2012 alone.
