Yes that is also my main point of view because gambling without having to set a specific fund to gamble would lead to uncontrollable lose as well, so as a gambler it's advisable to have fund you can afford to lose to gamble than following the rules number 7. which i think should not be followed to avoid misleading users who are yet to understand how the gambling works or those who are desperate to double their money would eventually go to increase their bet with the hope they would win in next the round or bet.
I agree with you, when gambling, you should definitely set a specific budget, which will not have any negative financial impact even if you lose, that is, you gamble with what you can afford to lose.
There are some gamblers who, after losing money in gambling, try to make bigger bets to recover the lost money and make more profits, which leads them to even bigger losses.
This is why it is important to have self-control when gambling and never consider gambling as a means of making money, gambling should be seen as just a part of entertainment.
We should be able to allocate some money that we can afford to lose in gambling, the behavior of people who bet more when they have lost in order to get back the money that was previously lost is wrong behavior because such actions will likely only make them addicted to gambling with the provision that it is definitely addicted to gambling. When you have lost, you should be able to accept it, and those who bet more after losing may be people who cannot accept losing.
In addition, there are also people who return to gambling because they use a strategy and when they lose they think that their strategy is not working and there is a possibility that they will look for another strategy to be able to make them win in gambling, this can be a repeated action. In fact, for slot gambling, it seems that there is no strategy that needs to be done other than good self-control.
