Let's summarize what has been reported previously:

1- High level of centralization;
2- Unfair wealth distribution (72% pre-mined with ~90% of it to the team);
3- Price manipulation (WP: "price capped at 0,4$");
4- Reported fake users accounts;
5- Potential lies about user activity (officially reporting 40,000 daily active users but explorer show rewards are given to ~2,000/day);
6- Questionable business ethic: Avoid questions, arrogant, lack of transparency + ban "too curious" users from chats;
7- Unclear WP (Only a vague commercial version, not very technical):
      - Fork of Pivx without the privacy features (zerocoin protocol) --> Basically fork of Bitcoin;
      - Browser itself fork of chromium open source code;
      - Unclear mechanisms (Terms of team sales of max 10M/y not clearly defined anywhere, economic projections very basic and unclear, burning unclear);
      - 0 fees policy may expose them to network vampirizing attacks;
      - Overall long term supply model unclear (no tx fees + decreasing supply + capped max supply + burning = deflationary?)
8- PRIVACY:
No mention about privacy in the WP or anywhere.
This plus some other clues indicate they are potentially recording individual browser history through activity.
What they expect to do with user data isn't clear.

What is clear is that these guys are planning to "press the lemon" as much as they possibly can.
They are not really in a logic of community-driven solution but a full for-profit Business Model.
They treat their NBX coin as a if it was a security (US investors to be careful with this).

Always Invest at your own risks and after thorough researches to make responsible investment decisions.
