That's gambling man.
Sometimes you lose, others you win.
But usually loosing is a bit more frequent!
... and losing is always bigger and more painful !
gambling is about 99% losing

Nope gambling is always 50/50 percentage of winning or losing, it will always be like that. So either you win or lose depends on luck and may be you really need some strategy too although the result of a solid strategy is not always good but its better rather than randomly gamble your money, this will just make you suffer more
