the Only criteria i Use is to follow my instincts and also follow my mentor .
I know that sometimes i lose but lucky that most of His advices brings winning for me, several times this year that i earned at least 20-30% each investments.
Actually, the instincts of the hearts and minds of others must always be balanced so as not to feel confused when carrying out any investment because without someone to direct, I think someone will also get lost if they only rely on instincts from ourselves.
