To get that certificate, you sign a form. The form is one page with a lot of white space. It says in very large letters: “I want to buy a dumb investment. I understand that the person selling it will almost certainly steal all my money, and that I would almost certainly be better off just buying index funds, but I want to do this dumb thing anyway. I agree that I will never, under any circumstances, complain to anyone when this investment inevitably goes wrong. I understand that violating this agreement is a felony.”
