That’s a massive win indeed but this guy must be a highroller as his stake was 10,000$ on 7 fold multibet. Chances you would win this are very low and I wonder what his ROI will be on the long term if he mainly places bets like this.
when a person manages to take 10,000$ and makes multibet bets then we are facing a very rich person who can afford to bet with very high amounts of money, it would be very interesting if the casino could show us his statistics so that we can see how many times he has bet with 10,000$, how many losses and wins he had until today, that would help and we can see if the guy is in profit or if he is in losses and we could also see if the guy is or is not a professional bettor.
professional bettors have hardly been making multibet bets and constantly, while guys who have some knowledge about the game and want to test their luck have been making multibet bets constantly, but they don't have a very large number of wins, their advantage is that with multibet bets odds of more than @5.00 is profitable in the long run, but we don't know if that's the case for this guy who won that amount of money
It seems that to show the statistics of gamblers the casino cannot publish, because it is one of the customer's privacy which is not to be published.
But I am more certain that this gambler has at least lost a large amount in the previous bet.
Because every big gambler must have had experience of losing at gambling. But that's just my thought.
