If you ask me, this is the right way to handle your losses in case you are actually going to chase them. In other words, martingale is the way to deal with your emotions as you come prepared for the losses (even though this approach doesn't guarantee you won't bust later, of course)
Martingale is not best for me because I long for big win and want to play longer, with martingale, I could wipe my bankroll if I am not too lucky and if I win, I will just win a small amount, not satisfying at all. Everyone have their experience on this method for sure but for me its not working anymore, and one thing I learn is never chase your loses in a fast manner, its not wise.
