I saw a video of someone giving him shit and him stacking "fuck you, fuck you" left and right back at the man. This guy seems to lose his cool quite a bit. He seems like an old fart but if you look up his history, he's bet millions upon millions of dollars, both winning and losing TONS of money.
Here's the recent bet/story ( could you ever bet millions if you had it? )

I never really understood the allure of gigantic bets. If you were to see that amount of money from his perspective, I think you would agree that it is not really impressive, considering how much money he makes/has. I bet that for him, betting millions of dollars is like losing a small chunk of his immense fortune. He has a net worth of $ 300 million. So he lost a bit more than 3% of his money.
People here have bet their entire life's savings. Or money worth years of saving up. If you ask me, that is both more impressive and dumb.
