The market should tank somewhat if miners centralize, but that hasn't happened because nobody cares. All these NGUs only care about NGU, and don't care about decentralization. There is no disincentive to decentralize.

NgU needs reasonably decentralized mining, we have reasonably decentralized mining.

I guess it depends on your definition of decentralization.
Sounds like cope, buddy.
