In my opinion, martingale with luck is very profitable, i earned 200k satoshis everyday without loss, just dont get caught by the house edge mates.
don't be greedy and know when you must stop maybe the main key for martingale , how much your capital to get 200k satoshis everyday ?
Every method can be successful but the only thing that would affect the gambler in a negative way is when they become greedy, when they are affected with their emotions. A gambler can only win if you treat gambling as your business and not just an entertainment.
