If we cannot afford to lose a part of our income, then we should not take risks.
If we only started from that premise and played intelligently there would never be cases of addiction, but it is impossible, not all people think like that, at some point they will risk more than they can afford to lose and that is when the problems begin, there is nothing worse than going into debt for making a decision driven by emotions, that is paid dearly because it is more effort, more stress, a commitment that is acquired almost unnecessarily.
