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.
So many projects are dead because they have absolutely nothing to offer the investors that have put money into their projects, their products are rubbish and unsustainable and with the kind of team members that the projects have now which are not willing to work on their own coins, I am not surprised that the coins are failing so much
