Why so silent here? Can we expect any announcements soon? There is also trading volume decreasing a lot, and that's sad

I think that it's not a problem. Nem is a very good crypto currency which has the future. Serious developer team is working on this project. Just be patient and hold and you will see that this strategy works.
I like the NEM dev team and their NINJA releases. Its the calm before the next big storm, I can feel.
