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.
Lol what is it there to video tape? @OP already shows the screenshot of his bets. So I do not think that there is a need of another evidence here. He also stated that he did not get any bonus despite of the huge wager he did for the casino while his friends received bonuses which wager less than him. @OP is not accusing the casino as scam but instead the bonuses it should give to any loyal client. Not because he is winning, he should be deprived of the bonus that is enjoyed by other player.
