I don't really think ETN has any future besides ridicules speculative pricing until people will start realizing this currency has no real use. Biggest point there were making is that you can use ETN on mobile and even mine on mobile but this is false - their official app won't allow you to mine because "they are still working on it" and then there a lot of people already mining ETN with powerful GPU rigs so basically their 'core mobile mining' is totally broken.
