if people are gambling for fun then they will stick with very least bet amount or they will gamble only for free like with faucet money. Then the survival of gambling houses will be very challenging.
That is the reason some gamblers are making good profit and they are promoting themselves as the winner in gambling and making others to follow him to gamble for making profits.
Yes gambling for fun will be an end to gambling houses.
Still there are people who want some realistic gambling experience and they will spend big money into gambling and still will expect only fun.
I agree this type of gamblers will be very less because in long run no one will be able to afford to lose big amounts. They will start having other type of entertainments instead of gambling.
