Yeah as you say the lack of mining is both a strength and a weakness, good in terms of no inflation or fees, but possibly bad as there is no incentive for the average person to run a node. I guess it is still pretty centralised, but whats beautiful about NANO is there is actually an app that works and sends fund in literally seconds.
I am really positive about the tech, the only worry is getting mass adoption may be difficult.
