Care to share just one single example in this space where a trading educator minted some brilliant traders yet had no clue how to make a dime him or herself? I never heard of such individual. I don't think it's possible.
This Industry is full of charlatans, more fakers than real traders. Probably 10x more. An example is our resident snake oil seller Mr KC, he hides his overall PnL only ever shows his volume. Wouldn't normally care, expect we have to endure his stupid hindsight posts.
