yes you may win one , two , ten times ...etc but if you keep repeating the same method everyday you will end up losing more than what you won in the previous days
I guess we'll see, won't we? I've known plenty of martingale traders within Forex and other markets that have been trading successfully for years. Raising a family on the money they're able to bring in, exclusively from martingale trading. There is correct ways to do it.
Forex is different. You're not fighting a house edge. It's kinda like sportsbetting, where you can beat the edge and play +EV if you're good at it. Dice games/bustabit (I assume the method uses one of those?) are almost always -EV, and mathematically, you will go bankrupt.
in gambling without +EV you can't make money
Yes you can. You are wrong.
Only in the short term. You can change your seed, make a new account, etc, but that's not going to change mathematics.
