The thing is, hype is somewhat ephemeral and will only last for a short term, there are many projects currently, and in the past as well that didn't have any worthwhile use case, but was just been pumped by hype, it took only a short time for the projects to completely fall out of the market, thus what I'm saying is, a project definitely needs more than hype to be sustainable for the long period, and even if a project wants to create hype, then they should also work on their network and try and have many other things to offer than just hype.

In my opinion, technology beats hype anyday, I think with a great technology and ecosystem a project team doesn't need to put too much effort into creating hype, and the project will definitely be sustainable for the long period, in summary, technology/development is primary, while hype/marketing is secondary.
