Is this coin dead?
Nope, the developers are working hard on Nxt 2.0. This will be totally different and will help the scalability problem of the blockchain and cryptocurrency world. Nxt will be again the second generation crypto, always on front with the newest technologies and always creating stuff by itself. Jean-Lux will publish a roadmap soon.
I heard there are old prominent NXT members that are going to fork Nxt 2.0 as soon as it's released and launch another distribution round for many, many many more interested users to get in. I like this idea.
I think there are only 1000 people or so that ever used Nxt, a new start will solve this. The world needs Nxt, but as things are now, nobody will ever have the incentive to use it.
