Before you gamble, you should determine how much money you will use. Limitations really help you to manage your money in gambling so you will not spend too much money. If you don't use limitations, you will still deposit more money when you lose without thinking about the losses.
That is why there is a saying to use your money you can afford to lose in gambling. That will not make you want to spend more money on gambling because you know the risk. You will limit your time and money and you will obey that as your rule.
Playing gambling using enough money is okay so you don't waste the money on gambling. It is our responsibility to take care of ourselves in gambling so there is nothing bad happens.
