Investors have lost faith in the ICO, which is why we see IEO at the moment. It is much better and safer than an ICO, I think you should not waste your time with an ICO because no project will really succeed in this form.
I'm not sure that ICOs are dead forever, but they surely are for now.
Perhaps as time will pass, scammers will forget about ICOs, but real developers won't quit it and investors eventually will come back to it too
