So as I predicted a month or so ago, Nav IS being DELISTED on Poloniex on the 15th OCT!
This is such sad news for a coin I have been with for over 4 years.
The lack of volume and unreliable network / transactions are my guess as to why.
A sad day indeed......
There's many reason's a coin may get delisted, but in my opinion it comes down to decentralisation & security
