and it is very likely that the main goal of this man is just for fame and maybe to be recorded in history..
No, I wouldn't believe on that, pulling the trigger for a $5 million bet is not easy, one should be fully convince that his pick will win, and that is his main goal which is to win, getting listed in the history is just another thing, he maybe even not aware on that.
I'm wondering on how such a person can able to risk a $5m bet just to be included in the history? For sure that doesn't make sense at all. For sure he though that trump will win that's why he's confident to put that huge amount to bet on trump but things goes crazy and now he lose and for sure he will be remembered in history as big loser on trump.
