I think a lot of projects are dead now because their creators weren't going to work on them. They just wanted to raise the money and then quietly leave. Scamers ¯\_(ツ)_/¯
Agree with you, they are doing icos and collecting 20-30m dollar. After 4-5 months we are seeing there is nothing still, there is no any software development or updates they are just talking and tweet something unnecessary, after few months they are doing nothing more and project is die.
