my strategy gambling is marti
martingale is literally the worst thing you can do while gambling because most of the time it is going to make you lose a lot of money
Since only luck can bring us money in gambling. All other strategies will work only in short time or even single time so don't waste your money in finding an effective strategy instead just enjoy these games sometimes when you're free. Invest some other places to earn money but not in gambling.
Why only luck? so you do not consider the knowledge and skills in gambling, I think you will increase your chances if you have those and luck is just a gift for a person to win in gambling in a good rate, but there are days that you are not lucky so it is better if you have the skills as you can minimize your loses.
Of course knowledge is also important because without knowledge in gambling you will end up losing more of the time, when you are gambling you need to understand the game so you know that is your advantage and how would be your approach.
