As I known, ICO is a kind of risky investment. Similar to the IPO which is the form of invite for capital investment, but when buying IPO, investors can research the information about the company they invested, find out about official finance reports and be protected by law when joining. In contrast, ICO projects are often rather ambiguous and unprotected by the government so the risk is so high for investors.
So how to evaluate a potential ICO project, look forward to receiving comments from you

Yes, you are right ICO project is indeed more dangerous for investors. Because the risk is even higher. But as long as I choose a good and promising ICO project, I will not worry if the ICO project is Scam. Most importantly I have to be really careful and do not choose the ICO project. Because the ICO project is actually a lot of profitable so we should not underestimate.
