The only strategy that can beat the house is to quit while still winning profits. This way the house can't have the chance to recover the winnings of the player. And best if the player withdraws it and use it elsewhere worthy.
The question is how much profit is enough to quit gambling completely? Most gamblers try to earn huge profits to try and change their lives, but they end up succumbing to the house edge later on and screwing themselves in the process.
Very, very few gamblers get extremely lucky by winning huge amounts and some of them quit gambling as you mentioned and invest elsewhere.
I think the same, sometimes when a person has a good streak and wins and wins, it is difficult for them to retire, all or the contrary, their logic will tell them that they have to keep trying to increase their capital more, and in this order of ideas each player Are you the owner of what you choose, if you choose to bet and keep winning? That's what happens in their heads, in how I'm a bit more conservative, if I see that I have a very large profit, what I do is start to leave the game and retire, before I lose.
But there are players who are not like that, who cannot control themselves and continue playing, the truth is they are very risky, but if they continue trying to get more profits, their winning streak ends and that is the danger, because they can lose everything.
Some players who have a lot of money, because they don't mind losing a lot, even though sometimes they do a great job because luck accompanies them, these are very rare cases, however here we can talk about self-control, about measures so that the person avoid falling into addiction, and other things.
My strategy is very basic, I don't bet a lot, also because my financial capacity doesn't allow it, I prefer to bet with little money and it's incredible, but when I see that I have profits I leave it there and then I go another day and continue trying my luck, when the least of my luck hears, I only see and accumulate, although it is not a short-term strategy, I can say that it works in the long term, but you must have a lot of patience, a lot of restraint, because there comes a time when One would try to make big bets to win a lot of money, but it is better to control oneself, because losing hearing what has been done is worse.
Some think that making small bets will never win, but they are wrong, unlike many players, I see the fact of playing in a casino as a business, as well as trading, because a small profit is a profit, it is better that nothing, then everything that adds up is good for the economy.
