It's great that NAV Coin has PR with a coin telegraph article.

SegWit, though, is not so amazing for bitcoin. SegWit may be good for Nav Coin because it would enable even faster micro-transactions with a lightning network integration in the future.

It's my view coins should strive to have most all of their major transactions recorded on the blockchain because this just makes it a more usable crypto than hiding transactions inside trusted 3rd party LN transactions. This is why I am not a fan of SegWit for bitcoin, but SegWit is useful if it is not used as a poor attempt at scaling (because it is not scaling), but it is used for what it is good for which is to enable additional functionality outside of scaling solutions. LN gets good when micropayments are involved, such as pay as you watch video and other technologies.
