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.
Unfortunately, fraud cases are one of the main reasons for this problem. After all, many teams of new projects simply seek to get money from investors, and then just hide. I really hope that over time the market will be able to find ways to combat this problem in order to restore investor confidence.
