I guess that hurts. Knowing that Biden won the election but as always probably this is a whale and doesn't care about his bet since no idiot will place bet with such amount if he is afraid to lose it.
Everyone has fear, even in gambling, in fact, I would say that I can afford to lose $1000 in a single game but I'm afraid to lose it, because that is my money and when I gamble I always aim to win, and therefore I believe this bettor is feeling down now.
