Martingale can work if you have the discipline to stop while you are ahead. The odd psychology of gambling makes that difficult. I remember at just dice watching people go up 30-40 bitcoins at times only to bust and lose their gains plus their original stake.
Yeah, I remember a guy on JD that would martingale with 0.25 start and would martingale until he made 30 BTC profit. He made 30 BTC everyday for a few weeks and only got to 64 BTC bet once.
wow that is pretty awesome
as i said martingale can work
but you need a much bigger balance !!!
it works until it doesn't .. better to mix it with some labouchere/ reverse labouchere and some random bets. In the end of the day it all depends on luck.
