I haven't tried martingale, when I'm new to this forum it was the first time that I have read. And after reading more post and reactions about it, I don't think that it's suitable for everyone. Most of those opinions said that it's not really worth for someone who gambles and that's why I haven't tried it. To the new gamblers there, you shouldn't try it but if you insist, charge to experience but the most important part was already given and told that you shouldn't.
