You can win in gambling only when you have a well thought strategy before betting and also you bet money you can afford to lose, have a lot of discipline to make this strategy work.
Basically 0% of people in the world can achieve this, but you can try. If you don't follow the rules you will play gambling without thinking and destroy yourself. Better quit.
The best I can tell you is, you will be richer and have more money in your pockets if you don't gamble at all. This one too still very difficult to achieve.
as far as i know, there are no good, 100% win, strategy in any game, not in dices, slots or anything else, and even if there is and someone knows it, they won't tell you that and will keep it as secret
if you don't want to loose money, try to find other hobbies, that will help
What if other hobbies doesn't give you bitcoin like gambling will? I think people that are into gambling always go with instant money and a lot of people are being practical right now if it doesn't profit they will not do it and if it is a hobbies they can muster up cash they will go for it.
