A casino will always have the advantage, and when a person wins, they should take their winnings and even half of them should be enjoyed and the other half should be dedicated to investing in anything, be it crypto, real estate, or something similar.
If the person/gambler have that kind of mindset, he will enjoy those earnings and it will change his financial capabilities, if you can divert those winning money to a new passive ways of investment, the chance that while enjoying your gambling you are also getting a good amount of money from your investment, though it's not easy and maybe there are few gamblers who are good in terms of controlling their bankroll but most of the time, those who's been so drunk with winning amount mostly ends up in losing everything back into gambling.
Do you think that controlling yourself is an easy task in gambling? This is one of the most difficult tasks for me. That is why before gambling one should be sure about the purpose of gambling. If a gambler is financially well and spends his busy days with his working, the word addiction will never come up. But most of the time what happens is long time gambling in a day leads to addiction.
I agree with you, controlling emotions when gambling is very hard and requires a lot of discipline. Even now after years of gambling my brain likes to play mind games with me and tries to trick me into playing longer than I should. Especially during losing streaks I feel the pressure to play one more round, because my brain tells me I am going to win and recover. It's all about staying rational and keep reminding myself that the odds of winning in a casino are independent and not cumulative. I think that addiction starts to manifest when we use money for gambling that we can't afford to lose and shouldn't have touched. Once we give into that pressure it's hard to come back. That is why it's so important for me to have fixed boundaries I will not break, one of them is to a fixed budget per week and month dir gambling. It gives me freedom to decide when to gamble, but once I reach my loss threshold I have to stop. And of course l have to stick to my own restrictions, there is no point in cheating myself.
It's more on how you condition yourself and how you seriously practicing your strategy, not easy and with how I understand your reasons it's really something that demand inside your mind each time you are suffering from losing streak, that echo who keeps telling you to try it again and giving your the boost that you will win on your next try..
