So hilarious to read such claim because I don't think gambler a exact person playing on a casino can earn passive income by continuous winning on a casino. They might win once or twice then conclude that its really possible to win always her, but in reality its not always like thay since not everyday you are luck to win each game you played.
But we have seen few users in this forum asking someone to bet behalf of them or they're complaining because the casino limit their bet, I don't think if a gambler keep losing on the casino, his account will get limit. A casino will limit someone account when the gambler mostly win and take their money.
But still hard for me if there's a gambler make a living from gambling, but we know they're can beat the house.
