ETN was a good idea, but the problem is why did it need it's own coin. Imagine if we had this on BTC?

That said the real reason ETN never mooned imho is because it was filled with new investors. There werent many OG's in ETN so people bought what they could in the ICO and most never bought more, which only left sellers.

Selling now is kinda pointless though, best to wait to the next bull run and see what happens.
