House edge ensures your loss in the long term. You don’t really need to think that hard to figure this out. Whether you use martingale, reverse martingale, modified martingale, random martingale, martingale’s boyfriend… It doesn’t matter… the house doesn’t care. As long as you are playing, the math works.
Don’t get me wrong thoe, I ain’t saying don’t play at all. You can play occasionally, get lucky and leave. That’s how I do it. As long as you don’t chase your losses, you can’t do no wrong. Be a responsible gambler.
