Maybe they do not have full knowledge about ICO, they think it is very risky. In fact, ICO is a new form of investment, with potential for investors, it is technology projects to develop different products to make a profit. However, many ICO projects have recently scammed investors, they take advantage of everyone's trust to do bad things. Besides there are many ICOs that have not been able to develop successfully as they have promised people. I think it is these things that make people have no faith in ICO's
I agree , ICO's got a really bad name because a lot of people scammed with it. So when people see ICO now they will instantly refuse it, but they forget that there came a lot of solid projects out of ICO's. I think if you just do your reserach and know what you are doing it can be profitable to invest in ICO's.
