I’m just trying to collect some data, also I guess this post will be useful for the rest of the forum users.
In my case, in 2018 I loss 32 times one after another using the dice system on freebitco.in.
Greetings
Well. My longest lose streak in a dice game using a martingale strategy is only 12. I suddenly stop when i lose in my 12th bet because i had enough losing more money, so i just prevented myself to lose all of my profit in kust one day.
