Remember that ultimately for a crypto coin to have any value, only 2 things matter: 1. Decentralisation 2. Censorship resistant.
Nano has both aspects covered. Decentralisation could still be better, but its improving. In any case the dev nodes have less that 50% now. Also by not forking after shitgrail and not succumbing to trolls requests, Nano is proven that it is censorship resistant.
