It is a fantastic return on investment. But the true value of ETN is in the developer's efforts on marketing and its potent weapon to penetrate the mindshare of public: the ETN "simulated mining" app. It will goes viral next year. Bitcoin is already going viral as store of wealth, Monero is penetrating the music industry more than musicoin, and ETN is poised to carry the crypto-frenzy further by penetrating psyche of the everyday smartphone users.
More users, more miners, more strength, more value. Investors will think, and they will invest into ETN.
