I know some of the celebrities from time to time, but no idea that there are celebrities who are aggressive in gambling. Those are huge stars right there Mayweather and Jordan, no doubt anyway they have a huge amount of money, so gambling all they want would not be a problem.
Mayweather is on a gambling spree because he can easily make millions in minutes, like what happened in his fight against Japan, but if Mayweather continues to do this he will end up like Tyson who lost millions and other celebrities, he needs professional advice I hope people around him are brave enough to tell to him, we all know he is very stubborn.
Also, Mayweather admitted he has always placed a bet on himself on all of his fights. So on top of the millions he got paid for from all his big fights, he also received his winnings from all his bets placed upon himself. Smart player and punter, indeed.
