in my opinion right now rest is not the right suggestion. It is true that lately the problem is that there are many scammer projects, but it would be better for us to do more research, rather than keep quiet and let the scammer project run, we should fight this trend. in my opinion, what is more developed in ICO or IEO projects is the idea or solution as a new innovation in the world. because to my knowledge the scammer project is very similar to the previous project and there is no new innovation though. So I think industries such as the ICO project are being further developed, so new innovations emerge.
for crowdfunding, I think IEO is the solution.
