<prompt> Human: I have around 40k which Im looking to invest through a friend who does forex trading. He has been doing really well for for the past 6 years or so. Normally his clients provide 100k minimum as an investment in his portfolio but has allowed me to go in with less. I would make 3 interest per month, paid out each month. The gains are certainly attractive, Im just scared that its fully based on trust that Ill get my money back. I would be signing a letter of agreement with him, which states that hed take on the full risk, but Im not confident that if anything should go wrong that itd hold up in court. Hes a good friend of mine and I trust that he wouldnt screw me, I just never invested this kind of money before and am a bit nervous. Is it highly ill advised to get into such an agreement with a friend based almost solely on trust? Or would a letter of agreement hold enough value in court to defend my position? Im really looking forward to getting into business with him and it seems like a great opportunity, I just dont want to get screwed obviously. Appreciate all advices.  <response>: So youre getting 36 APR and hes taking all the risk. Yea, ok, thats believable.
