Well be mindful of the fact that this particular analysis was not fundamental at all. As long as it isn't a scam coin (which it isn't in my opinion), it was included. This particular investment is based on two principles:

1. Reversion to mean (underperforming the rest of small cap privacy coins in short-term, ultimately should catch up).
2. A rising tide raises all boats (privacy coins are doing well hence NAV will do well).

Combine those factors with the fact that NAV is getting more buzz than ZEN recently (from what I have seen) and it seems ripe for a pump. I don't care if McAfee shills for NAV - he doesn't need to for it to pump. It won't pump like Verge did without outside help like that, but I don't ever invest expecting a 40x return - that's insane.

The other two questions you asked are fundamental in nature. This is more of a trading bet than investing - as such, those two questions are irrelevant (aside from strengthening the bet). Yes, compared to the mean for the group, NAV is undervalued (although there are other metrics that are better measures of this, no one looks at them). I hope that makes sense of it for you - in short, it wouldn't matter if their development team didn't exist for this particular trade (hence why I call it a bet / gamble with some edge).

P.S: Don't be salty - it's only just now starting to recover in BTC value.
