I always use the fibonacci starting with a $5 bet but there’s been many times I also lost my bankroll with it because I was betting the 2nd dozen and it went 17 spins without hitting (the little white ball doesn’t have a memory)so needless to say to say my bankroll was wiped out!
5,5,10,15,25,40,65,105,170,275,445……….you get the picture.
