I invested in April this year, and last night I cut my losses, losing $9,000. I learned a lot from this experience: the more someone recommends it and pushes it on you, the sooner you make a profit, the faster you should run or withdraw your principal; if you don't have a broader perspective and hold on, you'll suffer huge losses. People who try things out relentlessly will be told: "Hold on! The community is working on this; this is just the beginning!" Have a broader perspective (I've lost money on this old trick 100 times, but I'm still willing to try).
