Don't forget NXT is a proof of stake coin.
It is not decentralized and has a single point of failure.
Your second phrase doesn't follow as conclusion from the first. Why do you claim it has a central point of failure?
Who control the supply and distribution of NXT coin?
AFAIU it was like MasterCoin, an IPO-like thing. All coins were created in the genesis and distributed proportionally to initial investors. There's no inflation.
