Did Floyd Mayweather win the lottery? ?

He is probably smarter in negotiating his contracts when he fights than almost anyone else I can think of in the History of Boxing. if you pay attention to Pay Per View Buys for example, Mayweather has drawn more Pay Per View Buys than anyone in History. He was also smart enough to negotiate a percentage of the revenue streams from his fights. He's a smart man. You do know he lives in Las Vegas? He's been pretty astute when it comes to gambling as well.

Floyd Mayweather reportedly drops $2,000 on Mega Millions tickets. Don't feel bad if you spent $2 on a Mega Millions ticket Friday and did not win the jackpot. Feel good. Undefeated boxing champion Floyd Mayweather reportedly spent $2,000 Thursday trying to win the $1 billion jackpot, and he didn't win, either.

Im not sure but i think a lot of it was just borrowed from his friend 50 Cent. And he took a picture 📷 to make it look like a lot of money💰

maybe hes very rich

He's astronomically overpaid and loves to flaunt his wealth. One day, he'll come unstuck and regret it. 

He wins most things

Good morning Jean, how is the birdy ?
