First of all, this is nothingness but will more likely make your risk go higher and loose it all. Its not a method , its a common sense tip , like you should call or put depending on majority choice. You will not make any profit of these but instead you will loose it all. No one can predict a currency price. It all depend on your luck with huge risk , With my $20 deposit, i made it to $26 , loose it to $18, $15, $10 and then zero. Shall you buy this? Well if you buy, you will regret. But it all depends on you , it has some dead martingale method too, that will make your risk 20x if so.
I can't say that you will always win, as it stays risky.
You can do profit with this method, but there is always a risk.
