Definitely looks like a scam. Your website doesn’t even list any developers. Last commit on Github was 3 months. No new announcements on social media, etc. yet hashrate is still at about 40 Th/s? None of this makes sense.
Ultra-Pool has been working on a new mining pool. We have added Zetacoin to it. The GUI is basic and very easy to use. You don't have to give any email address or user names to be able to mine at ultra-pool. The pool support's Nicehash mining down to USB BTC Antminer's. Hell even CPU/GPU mining.
So if you have some old BTC mining hardware. Dust it off and start at mine at Ultra-Pool!
