I guess you are just too emotional, same here, when I played, I wish I have more capital so that I can wager max bet every game or even in every slots. But it is what it is, we have to take into consideration our budget and we have to play around with it. Specially if you have sort of experience better betting huge because you have big capital back then. But as time goes by, we need to adjust so that we can continue and play. As for the Martingale, it's a hit or miss strategy, it is still have some element of luck in order for this strategy to work.
