is it really worth the try. i'm curious about it and want to try it on freebitco.in. I also found a script online.
No it is not worth a try at all....
think about it, after three losses you are risking 8x your base bet just to win that amount
if you are going to martingale, start smaller and use 2.5x payouts so at least the more you lose, the more you win unlike martingale you simply win your base bet amount
