As we are in an era of cryptocurrency gambling we need to pay more attention to how much in total we use to gamble at a time and what are the outcome of our games, let say if you set aside 0.002 bitcoin to gamble with for a period of one week, what becomes the outcome of the total balance in bitcoin in the last day of the set date.
It is a good example, because as you say, if that is the total that you are willing to lose, then in the interval of a few weeks, let's say 4 weeks, you divide it and bet the same, either once a week if the results are positive or negative, obviously something always happens in the game, that when you don't pursue something you get it, but if you pursue it too often it gets away from you, so basically chance is unpredictable, it is something that is in that "magic" of doing things, that is why you have to put reason and not heart into this.
I don't think that everything you want too much will go away... there's also the law of attraction, have you read about it? I still think that everything is energy, the more energy you emanate towards something, the more likely you are to achieve it.
In the case of gambling, it may not be the case, because it depends a lot on luck, but in the rest of life, it works very well.
