Risk in HYIP

The fact is all hyips are Ponzi schemes. Think about it for a moment. What legitimate financial institution would payout at the interest rates that they promise? The money is simply shifted around in the accounts. My investment goes to you when it's time for you to cash. When there are more cash out requests than there is money, guess what? They shut down and take what they have left. The only winner is the owner of the site. They are set up to fail. Forget them.

Potential? All HYIPs are ponzi schemes. There are absolutely no exceptions. The only way therefore is, as you suggested, to get in and get out in time. Of course, you will never know how long it takes to call out the scam. This is the real problem. There was a time when it was safe to invest in new HYIPs because they would be around long enough to build credibility through gullibility but now you have sites that appear and disappear the same day. It is therefore really hard to predict. As the site gets older, the risk of default increases as the site will find an optimal time when to exit with all the money. There are better ways to make significantly higher amounts of money online, so my only suggestion would be to stay away.
