His base bet was 20 BFG, so 20+40+80+160+320+640+... with just 6 reds you are in -1260! What do you think about the longest possible losing streak? Just 6 reds on x2 is not a very long streak! The problem is not in Martingale, the problem is in greediness! It's simple math! With a balance of 1600, the base bet should be 0.000025, and you will survive +20 reds, with a 120% increase after every loss! If you just bet a double increase on a coin toss after every loss, after any losing streak your profit will be your base bet!

Yes, we all have been burned at some point! But I never blamed martingale for that, it's I who wanted to make fast money and I got busted with some longer losing streak... and just 6 reds on x2 is not a very long streak!
