That's why we don't have to think about it too much because we don't know the truth. Maybe it's true but maybe it's not. And if he is telling the truth and can show even more valid proof, he is really very lucky because he can win a lot of money from gambling because not many people can. We also don't need to be fascinated by other people's wins because everyone has different levels of luck. Maybe our turn will come later to get a win from gambling, so be patient until that time.
Maybe he is a new member registering on the forum to discuss gambling, but the evidence provided is not reliable enough from his statement so videotape evidence is more valid to be trusted, but he must be satisfied with his winnings even without expecting a bonus from the casino, but actually the most important factor is the platform is still legit because requests for high withdrawals are still being processed at any time. Hope you find the new casino platform giving bonuses as expected.
He is lucky enough to make big money out of gambling. It is better to feel happy with the win than feeling bad out of the bonus inavailed for him. Maybe the platform hadn't stuck to its promises. On seeing this thread it reminds me of the thread where a person losing 1.4 million in a single bet placed @!.01 and losing the entire bet comes to the mind. He's much lucky tha many other gamblers which itself a big blessing.
