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.
It is because most of the projects are just here for the short term profit that they can get. Beware there's a lot of them. You should consider taking a deep dive to every crypto project that you wanna invest in. Do your own research and do not just rely on social media friends.
