Trying any kind of system (betting or otherwise) without a solid knowledge of the game you apply it to is sure to lead to bad results. In this case, trying to apply Martingale to blackjack and concluding after losing that "the count was extremely negative and ended up losing all my money" shows that you don't know nearly enough about blackjack or card counting to attack the game intelligently. Here's why: even in a good count, you're not going to win many more hands than if it's bad. It's not the number of winners that makes card counting work.

That's obviously not considering the fact that Martingale is a bunk system anyway, so even if you were right and a good count would make you win more hands, you'd still go broke in the long run with the system.
