Knowing when to stop work well with martigale strategy. But Looks like greed is in our DNA and sometimes the more we win the more we bet. In the end we just lost everything.
There should be some counseling or thread how to cure greed in our blood
There's a lot of such counselling in many threads here. The main idea is to realize that it's greed, in the first place, is what makes them bet more and more until they lose everything. Some people wrongly assume that it's math. And they are applying that "math" in the following manner. If they are betting with 90% win chance or greater, they think: "Each bet is individual and it doesn't depend of previous outcomes. So, it doesn't matter how many times I won previously, my next bet has 90%(or more) to be a winning one!" But when they are playing with 10% win chance, they think: "I can't lose more than 100 times in a row, that's impossible. 20-30 times is okay, but definitely not 100 and more. If I already lost 50 times in row, I will definitely win with the next 20 bets.", forgetting that yesterday, or even earlier today, they were applying a different approach, which contradicts their current one. That's what greed is making out of people. They are ready to create a "math" of their own, only to justify their inability to stop.
In short, you can have fun with martingale, or with any other strategy, but your win, even though it is very likely within a certain (read "small") amount of bets, is never actually guaranteed.
For a dice game with 50% chance of win and 50% chance of loss,
What is the probability to win if you bet always on the same number/side/colour :
After 1 loss?
After 2 consecutive losses?
After 3 consecutive losses?
After 1 win?
After 2 consecutive wins?
After 3 consecutive wins?
Does anyone know the answer please?
