Yes a lot of project die indeed, there are many factors that have influence like uncapable teams, coins with only ideas and no actual project, scams and coins that just don't have such a long breath to survive in this market. We can only hope that recovery comes soon, I think most coins will follow if the big guys move up.
I like a project that already has an integration on some level so it has an actual use case. If the product can really be used and be more then just a 'lightning fast & anonymous' coin.
