The best choice is to have a strategy and use money management. In such way it is possible to increase bet size and not cash out. Or don`t make the main goal to return your deposit and withdraw small enough sums time to time. I`m talking only about sport betting, i don`t try to take profit in random games - it is just fun for me.
In my situation i once per week withdraw 10% of bankroll and recalculated bet size. I`m sure that it is not optimal, but it worked for me.
If you do really want to buy something then it will really be that always the best option is to make use of these winnings to be able to buy on what you do want to buy before and it will really be that better that you should really be that sensible into the actions that you should gonna take and not really that trying out to be impulsive and really that make your greed control over you on which this is the usual case.
There are really just that those situations that mentality of a certain person will really be that definitely be thinking up this way. There are those moments or times that you will be that skeptical because you will be thinking that you might be that lucky even more with the current situation that you are in. There are really just that those moments or time that you will really be that wanting to have more and this is why those winnings would really be that totally be given back or losing back into the casino just because of those kind of hopes on which this is really that not recommended.
Without using maths it becomes to easy to lose control. But when you have an algorithm what to do in each situation - it becomes much easier to control greed and fear. With money management you know(for example i`ll use my situation) that you`ll get some money on Monday. And the bet size you can change only after withdraw. So, you`ll just continue betting events you analyzed and don`t care about the result and bankroll.
