Honestly, this was really a huge sum of money this gambler played with, which shows that he may have this money in excess for him to have been able to afford to gamble a whooping $30million on a single bet, predicting who is likely to win the just concluded US Presidential Election, and I'm happy he actually won his bet, as I'm sure these are the kinds of people casino usually limit their earning potential, due to their high risk ability to risk everything. Because though we have seen celebrities, in the likes of Drake wager a million dollar. This is indeed the highest wagered amount I have come across.
This bet is getting so much attention because the amount is huge, you are right to mention Drake, who bets millions, this is an indication of how a wealthy person can act, but I have never heard of him betting millions. So in this case, the bet could have been made on the 30th for the reason that he could have known how the election would end, I don't know if that is possible. I would also like to know when he made this bet, on election day or earlier, because that could also be significant.
