yeah thats true, we all know that we can actually win in gambling but after that I will gamble again my winnings then after that I will all my winning because of the greediness that we felt is always there when we wins. But not all person are like that, some of them that wins the game will put their winning in their savings.
gambling is all about luck so there is one thing i always try and it kind of working i just bet all my fund with x2 one time per day i start like that and now i just bet with the profit i get from last day. that will show if you are lucky today or not i stop after that one bet even if it is a win or lost.
and the profit is getting bigger each week.
It is good that YOLO is working for you. I also tried that once but it does not work for me. I guess I do not have enough luck to win even if I use YOLO or martingale or any other gambling techniques out there. So I stopped gambling so that I will not cry if I lose big amount. Good luck with your technique.
