Once I went all in and I won a lot. Later I did it again and lost Never go all in !
That's a typical situation in gambling. I've done it many times. At first you win, then you win more and then you lose all. The only way to avoid big harmful losses is to not gamble with the money which are big for you.
Hmm.. From what you write here i understand that you won, but you continue to doubling the rate and in the end lost. This is obvious! It's called lose because of greed my friend
Next time take all won after the first doubling, and do not test your luck too much ..
