The problem with personal experiences is that there is a lot of bias, if another member says that it has worked for them I believe them in the sense that I do not think they have suffered catastrophic losses yet, but the math is clear, martingale has been disproved mathematically over and over again as a technique that works as it does not change at all the probabilities of the game, taking this into account the only reasonable explanation for those that argue that it works is that they have simply not used the strategy long enough.
The problem with personal experiences is that people like to show their strengths and hide their weaknesses, which is why they will brag about winning and keep quiet about losing.
That is simply human nature, we like to display our strengths while hiding our weaknesses.
They only do that for the sake of views, a lot of people are interested in this strategy and they would not watch if this strategy is not working. Everything that we saw in social media, especially on youtube could be biased, remember that the main intention of the uploader is just to increase his views to make more money. Maybe we just need to experience it ourselves so we can tell based on our real experience, but I'm sure this would not work to anyone.
This is a common sequence that you see almost every time you play and place a large number of bets. The real madness is when you play dice (<> 49.5%) and get 40 losing bets in a row. It happened to me, but I tested different strategies and made a huge number of bets, and to see such a sequence, perhaps several hundred thousand bets were made.
