Well, no, it's not.
NXT is a LEGO Robotics Microcontroller. A real thing that actually exists and is actually worth something.
(Well, alright, it's been superceded by EV3, but I haven't opened mine yet; there's still 34 days to go...)
It's fair to say that our Low Orbit Helium Assisted Navigator (LOHAN) mission has attracted a broad spectrum of sponsors, and among those who've climbed aboard is NXT, which aims to be the first cryptocurrency into space, or at least the stratosphere. NXT is a Bitcoin rival launched in 2013, "currently positioned at #5 by …
1. "developer" insta-mined all coins - basically gave himself ALL of the coins out of thin air (forget fair and honest distribution), whereas bitcoin/real crypto coin miners have to spend a lot of investment to get coins by mining.
2. then a portion of these was distributed amongst his friends, family and cronies under the promise not to sell immediately but wait and create artificial scarcity to increase value
3. then the nxt value was inflated even more by a huge pump and dump fraud several times
4. and now you have a shitcoin on life support, full of bagholders while the ponzi group already cashed out most of their fraudulent profits.
Nxt is a proof of stake coin. There is no mining, hence no "insta-mine". The initial development was funded by crowd-sourcing, which anyone in the public could contribute to in exchange for an early stake. 73 people did. That was roughly a year ago. Since then the coin has had massive development, with many innovative "2.0" features being added, including messaging (with/without encryption), an asset exchange and a marketplace that runs trust-free. More features are on the way. As such it in no way matches the profile of a ponzi-coin, which are generally clones of Bitcoin or similar with no innovation or serious effort put into them.
