I don't think you'll lose if you roll only 50 or 100 times.
Of course it depends on your bankroll, but I think someone playing martingale should be able to cover 10 losses. The chance of that happening is 1 in 1024.
I do agree with you that you will lose eventually. I just think it's not likely to happen within 50 or 100 rolls.
The chance of happening 10 loses in a row is a lot more common than 1/1024. I don't know how you get that number but do you realize that every single bet is independent from each other? It seems you don't, like %90 of matingale users.That means you cant exactly predict the time of that +10 losing serie(s). You may get 10+ loses in your first session. than bam. you re out.
Of course it can happen in the first session, but it might as well happen in the 2000th session.
Yes, I do kno w each roll is independent. That's how I calculated the chance of 1/1048 of losing in a single session.
Assuming you have a 50% chance, 10 losses in a row will be the chance of 0.5^10=1/1024
So if you would try unlimited times, on average you'll lose 10 times in a row after 1024 times.
Please prove me where I'm wrong.
