Many of us have experienced experiences like yours where we mistyped the betting money, which caused us to experience a bigger loss than we expected. But it has all happened, and we can't do anything about it or even try to recover from that loss. That could make some gamblers think about activating the self-exclusion feature so they can't use more money. But some people type the wrong amount of money that they want to exclude from those who originally only wanted to write down half of the total amount of money they had, but instead, they wrote down all the money. But if the person has strong self-control, he doesn't need to activate the self-exclusion feature because he can control himself when gambling and can also manage the amount of money for gambling. He also won't lose much money because he always uses small bets whenever he gambles.
Of course, limiting the size of bets and the maximum amount you can lose is quite important, but simply not allowing casinos to give credits is enough. Then it will be impossible to win more than the player's balance. And restrictions sometimes due to software and other errors can simply not work
I guess you made mistakes with is and isn't here, I was able to detect it due to the incoherence of your discussion even though I was able to understand what you wrote to an extent. Many approaches work for gambling, it is we who should know the ones that work best for us. Limiting the time of betting, betting with a small amount, betting only what you can afford to lose, betting with a sector of gambling only, abstinence from betting for a while etc, are all good approaches to moderate our betting lifestyle, and the ones that works best for us is what we should use the most. For example, reducing the amount of betting per time has been a very good way to gamble and get to stay on without losing much money. I urge gamblers to do this often so that they will not just be wasting money, especially on the casino aspect of gambling. This is the issue that has been discussed here many times and the limitation to it is the money, much can't be made either. But when the account is well managed, the end will surely justify the mean.
