There is an MLM element to it but the referral/recruitment side is optional, the only thing is it is hit and miss with who you sign up with and if they are actual traders or looking for a short term hustle to sell courses. It is not a secret to make money per say, since you need to actually learn forex and go through a training plan, from there trade on a demo account ask you're mentor whenever you struggling. You can definitely learn on your own though if you're brave enough.
