He is very greedy indeed who refuses to withdraw such a large amount from just $4. It's hard to accept that no one would cash out because it's such a big Odd. He had confidence that his side would win which is why he didn't cash out but luck played a different game with him. He lost his bet his chance. This is his great misfortune. I certainly wouldn't have missed that opportunity at $444 or if $200 was offered for $4 I would have cashed it out.
That's relative. You might as well argue why every gambler out there doesn't just withdraw their winnings, when they are on top of their game and have gained the peak.
Because we live in linear timeline and we can't see the future. If he would have won, people would be calling him lucky instead of stupid or irresponsible.
The fact that he seeks donations makes sense, as you would want to ride the wave of publicity. Sadly this kind of publicity doesn't work. For some reason people avoid poor people like a plague. They must be subconsciously thinking that some of that poorness with brush off to them.
Because when rich influencers ask for money, the opposite happens. Remember Pauly0x (influencer) in twitter giving his ETH address and saying that he is offering to his followers “absolutely nothing” for sending him ETH. He got over
$1M in eth in 24h. People are weird like that.
