I just noticed that site makes $1 million per month from memberships ($200/month x 5000 members). This explains a lot.
Now the question is: Where are their customers’ yachts?
Why is the size of his trading account less than $10m when he is making risk-free $1m per month from his students? I would expect a successful trader to have a much larger account size if he's earning risk-free monthly income of $1m.
If I'm a potential student/subscriber, this is the question that I will ask him.

The website says they provide many traders as educators, so it’s not just one trader.
Though of course you can find another argument against them in 5 seconds
I’ve actually been wondering if educators who make money are such a bad thing, because on another hand so many people look for good educators. How would you evaluate them?
