Personally I am not interested in how to double money because the results are not certain to be good and according to our expectations I prefer to play fairly and not force things that are not in accordance with my own abilities.
For example, I want to bet I will look at the contents of my wallet first and if I am sure I will play but if I am still in doubt then it is better not to.
And if at that time I win then I will take and immediately cash out the winnings to enjoy with happiness and return when my condition and situation are back to normal.
