Ah, good-old NXT. It was one of the early PoS coins that was innovative in its time. The ability to create tokens (assets) without coding knowledge was truly unique. I had some old tokens that used to generate "dividends" just by holding them over time. While it appears the NXT project is now "dead", the team made a new coin from scratch with the same tech and design as the original project. It's called ARDOR (ARDR) and it's still being actively traded in the market. I'd say this is more like a re-branding. Same as Burst (which used to be a PoC coin that can be mined with a HDD) which now changed its name to Signum.

And let's not forget about QORA. That used to be a good coin back then. It helped make the Internet more decentralized. Similar to Zeronet but entirely based off Blockchain tech. Who knows? Maybe some developer (or group of developers) will revive these projects. One can only hope...
