I don't live in the US. All parties live in the UK. CFDs are more common than stocks over here however I have never traded them.
Back in the 90s I started trading for others and I lost half of this couples $25k account in first week by making good trades...well...I lost too, then wife comes up to me and says her husband had penned in her signature on the account and that money was going for down payment on a house, they had three kids. Pluck, she took me to house they were going to buy, so I told her on day they make an offer, I reimburse "her" in person. She had brokerage wire her fund next day and three days later she made an offer and I gave her what I lost, never will forget her smile. She later divorced, and she still invites me over for dinner every couples months no matter who she dating, still living in the house, have gone to each of the childrens' graduations and walked two down the aisle. You sometimes have to bite the bullet, you make mistakes and this is certainly a business to do the right thing. If I don't have my money into something, how can I put ALUM into it? I know it is eating in to you by words you wrote in your post, it most likely eat you for years. Either money or working for free sounds about right to me, how about you? Make an offer, show your friend's boss the man you are.
