Martingale method may work for few people that are lucky enough to recover the losses but for most people it will never work. Rather it will just going to make the losses become even more bigger. I will never ever recommend this to some for people who are worried about the losses they have made when they are planning to chase for it and try to take it back. I simply suggest to cool down call it a day and get to gambling on the other day or on the next day. It is hard to see people getting broke because of this common mistake.
