Well, I don’t completely agree with you. There are so many profitable traders out there that recommend reading some great books. Hence, dismissing the hard-work of the writers completely doesn’t sound that great to me.
there is an old saying, those who cant trade TEACH! haha but not all books are bad, but i would stay away from sketchy trading courses online that are sold for a price. when i first traded with hotforex all i have was you tube and some free online introductions and just learnt along the way
