Calling martingale a strategy is like calling burning money a strategy. Most people gamble because they want to get rich, which suggests that they are starting with a comparatively small pool of money, and most big casinos will have quite large reserves which are many times bigger than the average player. If we are considering that every play is equivalent to a 50/50 chance of winning (it's not - the house always has at least a slight advantage), then you are guaranteed to run out of money long before the casino runs out of money, it's a simple numbers game. It also relies on greed, which is where the casino always makes it's money back - a player simply doesn't know when to take the money and run.
I do agree into the words you've said about burning money strategy when we do speak or talk about martingale on which this is indeed true because on the moment that you would be losing up a roll
then you would be doubling up your base bet and so on. Yes, it could be profitable but once that losing streaks hit you up then it would really be something that will be ending up on a blown gambling account
or simply your gambling capital or bankroll would vanished in thin air. I have that worst experience on using up this strategy on which i could say that this is the fastest way on blowing up your gambling bankroll. lol
Actually this is something a strategy that is commonly used on dice,crash games and other casino based type of games. Being consistent with it? Its not bad as long you do have that budget
allocation for gambling session and wouldnt be ending up on depositing more on the time that you have blown it all. Play according into your leisure needs and never intend to chase up loses
because this is something that will make things even more messier.
