It happens to all of us and Drake is such a rich guy that I don't really feel bad for him losing such large amounts. It's cool that he shares his betting slips online with his fans, but this could also be a marketing campaign for him. We don't know what kind of deal he has negotiated and maybe some of his losses are being paid back by the gambling companies. The good thing about sharing his betting slips before the fight is that we know it's not rigged. Drake lost already a lot of money through his betting, but if you put the money in relation to his total net worth then it not so much. Everybody shoudl be betting within his own means and only use the money he can afford to lose. I just hope that there aren't any young kids that follow Drake and think now it's cool to bet such large amounts on a fight and want to do the same. It's clearly fun and entertainment for Drake betting on these matches and he isn't doing gambling as a side business to make some money.
