That is an interesting question, I really think that part of the answer to that is that people do not understand probabilities at all, many sites recommend martingale as a winning strategy either because they do not know better or just as away to try to incite people to gamble, but make no mistake martingale does not work, even if you have a 99.99% chance to win every single bet and a 0.01% chance of losing if you bet for long enough you are bound to lose and when you lose you will lose all of your capital.
I think it was a year ago when I become active in gambling that I participated in a discussion of a newbie exploring martingale it looks and sounds logical because you have to just double your bet every time you lose and you will eventually recover all your losses for the last ten rolls, it's very attractive for newbies but if you asked those who are very much into dice there are losing rolls that can go up to 20, I haven't reached that, my highest was 16th but with a house edge in favor of the gambling site, it will eventually catch you.
This has happened to me and in the end what happens is that you are out of money unless, you have more money to play with and add funds to the site and make it double. But once you cross 10-12 reds the amount to bet becomes higher and its difficult for many to take more chance beyond that unless you are rich to bare the further loss in case if still the red keep on coming for 15-20 rolls continuously. Better to set a limit by yourself that beyond x max red you will not bet it.
10-12 streaks are too much to bear, i start with $1 and it's still something to think about when you experienced the successive 5 loss, sometimes when this happens while playing with dice, i'll just try from roll under to roll over. sometimes it breaks the 6th. i think i've read this strategy here as well. but then you got to learn when to stop though. always remember that the odds are always in favor of the house.
That's already 16 USD as your base bet if you look at 5 streaks, it may not be too big but if you get into 12 streak max, that would be 2048 USD bet to win 1 USD, the question is, are you willing to take that risk?
