I bet I could sell a course marketed based on my LN market w/l ratio. If I did I could probably make more selling the course than trading for the following reasons.
1. People are bad at math and don't realize getting rekt 1 out of 20 trades is still a slow grind because it take 10 wins to undo that 1 loss.
2. I'm not betting the house on 10x leverage. My trades are lunch money scalps just for fun.
3. Successful trading requires tons of patience. I spend most of my time with no open positions waiting for a good entry. I could spend that time marketing.
