Yes, limit the amount played in the casino to overcome not going bankrupt, because there have been many cases where they did not control the budget for gambling and ended up losing everything.
Just 5% of the total income is more than enough because the purpose of playing in the casino is only for fun not profit.
But somehow until now there are still many people hoping to win a big jackpot from a small budget.
Before getting into gambling one thing must be clearly understood that in gambling its the casino who is the ultimate winner, while gamblers mostly lose money in gambling. It's best to invest in gambling that you can easily afford to lose and it's also equally important that you know what's your limit to quit. If you are losing then quit once your allocated quote is exhausted. If I want to have fun then I will prefer going to dine out with friends rather then placing bet.
