There is a way, and as an investor it should dawn on you sooner or later. And it works in every state I've invested in. Of course in my case it's not a problem because I have a broker's license and a referral fee is not a problem for me to receive.
I'm only posting this to keep you thinking, and I'm not revealing it now because I don't want every investor I've helped with this to now have a ton of competition, including me. At least until I've left this planet.
So when it dawns on you, use it and don't broadcast it, which may be hard for you because you sell a course.
