just remember that your experience is not universal
even though your main goal when gambling is to make money others won't care about it or simply will have other goals (show off, have fun, etc) before making money, they could see making money as a plus factor, something that adds to the fun, but not the main thing that would motivate them to keep gambling or to quit it
You’re correct since there’s no universal strategy that will work for everyone although he mention on his that the strategy don’t apply on
him so he is not generalizing his statement rather just sharing an experience that different from others.
I’m always gambling in calculated by availing bonuses and tournaments while wagering using my bankroll normally. This way I will have other goal that can be achieved using my normal bankroll instead of no bonus.
I have limits on how much I can spend so that can control my losses to don’t exceed the amount of potential bonus that I can get.
