Thanks for sharing, I believe nano is one of the dark horse or sleeping giant, as you say zero transaction fee, instant, and fast transactions. There is no blockchain just like nano it is unique. Personally I am holding this coin, I have witness from the previous month to this day it grows its price from $0.8 to $1 + which is really good for holders. Nano ATH was $33 if I am not mistaken it really has some potential and projects like this for nano are amazing.
I agree with you here. Nano is like a sleeping giant. If they will continue to expand their use case in the market, this maybe one of the alts which is worth holding for. And it seems that the nano team is serious in exploring other opportunities for this platform. With their zero fee/instant tx, this project will go a long way. So they really have capability to make it valuable in the market. But for holders, you should still closely follow their updates and developments.
