That means that let a bot free martingale 24/07 will only slowly make you lose money
Actually, it won't make you slowly lose money. It will make you slowly gain money and then suddenly, unpredictably, lose it in one fell swoop.
Yep, I don't think martingale will work for a long time.. So, its better to bet big and set your target profit.
there is no such as winning strategy here, if there is such strategy, why would anyone need to work ? and why would someone open up a gambling sites? it will better that everyone play at the gambling sites if there is such winning strategy
