If NXT was a scam. It's a pretty good elaborate one..... Hell, its the most successful scam in pumping out quality features vs EVERY other coin out there.... seriously...
Like I said, most elaborate scam ever:
Could be a mix between the two. Maybe I'm viewing this too black and white when it's more of a gray situation.
Do you know what a scam is ?
In every scam there are victims.
Find me one single victim of Nxt - the cryptoplatform (yes Nxt is not a crypto but a platform to develop business and experiment with the blockchain).
Pro-Tip : You can't.
