Martingale by itself does not have anything to do directly with gambling addiction, if we are objective and neutral on the topic, but it has much to do with the rapid loss of bankroll and recklessness while gambling, which could eventually indeed lead to addiction to gambling.
There can be someone who is responsible with their gambling and assigns a small amount of their gambling budget to try martingale for the sake of fun, they end up losing their money and would not chase it, because in the end they got what they wanted, to have fun with a little bit of money they could afford to lose.
I have never used martingale, because it is often associated to people who seeks to get profitable sessions and money out of casinos, which is very risky and does not go with my gambling style.
I agree with this. Martingale has nothing to do with addiction. You could say that if you use Martingale you will bankrupt yourself sooner than you can get addicted, so you are safe. This strategy is more about greed and ego, you think that you are so smart that you have found the golden ticket of gambling and will make a lot of money this way. It has never worked out positively for anyone, and will never work out for anyone in the future.
Martingale strategy will lead you to heavy loss, because there is no guarantee that you will win your next bet if you double the lost amount. There is no gambling strategy on earth evented by man that can give you constant win in the long run because gambling is based on luck. The most skillful gamblers on table games will definitely run at loss in the long run because they will never be satisfied with their wins and would continue gambling.
While you are correct of martingale not working (it's proven not to work), rest of your text is contradicting itself in many ways.
I am assuming that when you are referring to skillful gamblers on table games, you are talking either about blackjack or poker, which are the only games that require skill as well as luck. Anyway...
Most "skillful" players wouldn't use even martingale, because that has nothing to do with skill. Nor they would be driven by greed. I am not sure how you even mad that leap, because i can't see any connection. Why skilled gamblers wouldn't be able to quit? It's a part of the skillset to walk away as and accept your losses.
He just wrote some low quality nonsense. You can't call yourself a skilled gambler if you are unable to win for sure.
