Personally when I first saw it my initial reaction was that: I wouldn't touch it with a 10ft pole. It just looked like a suicide investment for me.
I've made a bunch of predictions on this site. Many except 1 came true.

Hshare, Bytom, Komodo,SONM quadrupled.
BCH went over $1000 (I made the claim on early August)
I was screaming about WTC while it was 10 times cheaper and I predict minimum $100 before next christmas.
I was big on Substratum and Sia
I was screaming about MaidSafe and NEM

So I do know a thing or two about investing even though I'm pretty much a noob. If it makes short term gains, go for it. But I see no long term value in ETN. It's a real piece of garbage IMHO.
