I don't think any good and promising project wants to push their luck and going for ICO as there is IEO and everyone prefers to use it. Sure since they were the project with real-life worth but that doesn't mean there is no risk when investing in them (look up unicorn startup).
Speaking of risks, all the things that are done by each person always have risks that they must understand well, only in terms of investment, one must know the direction and the concept is clearly clear, this is to make someone dare to take risks when investing.
