<prompt> Human: I have also asked rinvesting with the hope of getting more technical information about it. I realize though that PF had more people and has much more attention, so here goes. A week ago, a business associate of mine told me that he had The deal of a lifetime that I would be stupid for not allocating company money to. Both of these were huge red flags, but I figured I would entertain him and read over the brochure he sent me for this company. Long story short, they are trading gold Forex using a martingale system on margin. I have tried to explain to him that using a martingale doesnt ever work in the long run, unless you have infinite capital, which of course he nor this company have. His family has invested in it for the course of about a year. Between just him and his dad they have I believe 75k in it, his mom has more he believes but isnt sure the exact amount I have reason to believe that its more than him and his dad do together. He and his dad have done some test withdraws from the company, and they seem to work. I told him hed be wise to withdraw the entire amount and just say good riddance, but his dad is convinced its legitimate because hes been collecting 2-3 per month for over a year. He realizes that if Im right, itll be an absolute disaster for his family, but is convinced that Im wrong because Im not an established stock trader. So, in the end Im hoping for a better argument that i can make to him.  <response>: Have him read the comments section in response to your post.
