The project is not about "Refunding after 1 year!" Its a normal ico project but there is a strategy to make investors feel confident at the project - which is Risk free investment method. So don't spend all over the thinking on risk free thing. Its just a side. All we have to do is read and read about the project concept, field and invest on it if it really be succeed. If the project looks unsuccessful:  no mean of investing Eventhough there is a risk free method. In that case I see a practically success.
