who said anything about being worried about making extra money?
This website is dedicated to helping each other improve as traders. Obviously a fact you have not grasped, I have watched the videos several dozen times and have taken all the notes I can. So I have decided to offer them for sale. If I sell them fine, if I don't thats fine too.
I am trading full time for 4 yrs, and I still have no problem spending money on my trading education. It's the only way to improve, besides live trading.
The real question here is how could you ask such a stupid uninformed question "why are you worried about making extra $$$ selling the course?" , to someone you have never met?
