I can relate with your experience. I have a friend who was a victim about 2years ago. He invested with everything he had having seen some people get huge returns from the investment not knowing it was all a set up. He nearly committed suicide. He's still not fully recovered. As far as I'm concerned, investing in anything that promises huge and enticing returns with no definitive means of generating it is not advisable. The legit ones usually come with moderate returns within a feasible time frame. At least, making a little profit is still better than loosing it all
