I expect the price of ETN will stabilize at around 0.07-0.1 $ in the following days. Please bear in mind that the ETN is a privacy coin just like Monero, Zcash, Verge etc. and therefore will be faced with an increasing demand in the future. In a few months the price will probably rise to about 0.5-1 $ a coin. Next year, the total crypto market capitalization will be at least 10-times higher than it is today. Within a year or two the ETN can realistically hit the price 5-10 $ a coin.
That is reasonable to assume IMO. ETN at 1$ a piece is only 1% share of the entire cryptocurrency capitalization. That's 14x from the current price!
Yes. The holy grail in crypto is a patience, especially in case of the projects which have a great potential in the future (e.g., either they introduce technical novelties like IOTA or have a huge number of potential users like ETN).
