Well, I have been scammed before and I have also learned this thing myself. I was scammed by HYIPs and I learned the lesson. I still monitor HYIPs in order to find out what HYIP has become a scam. However, I NEVER invest a single penny in those HYIP programs ever.
When you're very convinced that most of the HYIP programs are scams, I don't see any reason why you should still be wasting your time and energy in monitoring them. When you no longer have any need to invest a penny in any of them, I believe that it's time to move on completely.
