Given that Drake is the official ambassador of Stake, I wouldn't be surprised if he
staked that amount of money in order to promote their brand. Additionally, I fully believe that majority of that money is sponsored by their website which came from the pockets of Stake itself.
While I do think that Drake is an obsessive gambler, I doubt that he would bet that amount of money in a small amount of time. With that kind of spending in the gambling, it is just too obvious that majority of that would be sponsored by their gambling website.
Do you remember that we have topic here, discussing that rich people have less chances to become gambling addicted. On Drakes example, his involvement in gambling industry and bets he made (he bets on every major event), have your opinion changed? Without Stake advertisement contract, I think he would be gambling similarly, same amounts and frequency of bets. Can we also consider that Drake is addicted to gambling?
I remember Drake playing a lot, but I think he still does it, he surely does it for publicity reasons, he surely doesn't have any problems, the fact that he has so much visibility surely makes him a person who gets paid to make those crazy bets that he does, no one can get that out of my head
The capacity of a person to gamble is relative as it depends on the amount that they are willing to allocate or budget in it. With Drake's influence and status, he definitely has the capacity to do such kinds of crazy bets. Given the fact that he is the ambassador of Stake, I really wouldn't be surprised it this would be one of the reasons on why he would experience financial troubles in the future.
