Sorry for my bad English. I'm french Canadian.
I have seen on many forums, that a system good or not will eventually fail.
This fail, for me has for meaning that you overpass your bankroll for playing or you lose all your money.
Two thing that nobody wish to happen.
In my system, it's possible to lose some bet, then I don't say that i never loose,
but with in some kind or martingale, I am still winning since a long time. (real money)
After how many bets or turn do you considering that a system look good?
I played on a casino of state, when I believe they can be trust.
I'm around 10 000 turns or bet put on the table, and I'm still winning.
