Because most of the ICO project is more like a hype, they didn't have any meaning, from their white paper can determine that they are unlikely to succeed, so I think now is not a good time to an investment ICO.
Not just being a hype, most ICO now are scam. The only true and good ones fight to list in a good exchange. I think project team these days no longer take time to make plans and implement well on the project setup. This is very bad.
