no betting strategy can ever turn a wager with a negative expected value into one with a positive expected value
someone that claims to have an edge using any kind of martingale strategy is foolishly mistaking short term results for long term results
enjoy your winnings, and realize that they are not sustainable!
You just take the risk to win your first bet, after that you can't lose (if you're not crazy) and you can gamble your way up.
I won my first 7 bets and got from 7 to like 25. And after that to 360.
