That should be expected as it is a natural principle. Most projects are dead because of poor management by the team members because they lack the expertise in crypto and failed to seek for counsel from experts. Also, projects with no backing product or tangible ideology behind is likely to go down the drain as it will lose the interest of potential investors.
of course technology and products must be the selling power if you want to make the ICO project a success, even now there are many ico projects that innovate and have no technology background, that's why many ico projects become shitcoin because developers just want to get as much money.
