I think there is still hope yet. Etn will be one of those coins that shoots up when you least expect it, just like many did, late last year, that were stagnant for years.

I see the real value being in the partnerships and patents. Once it is all working and being utilised. If they do it well it will knock a lot of the fud away and start putting upward pressure.

I just hope they don't make any more big mistakes.
Anyway even if you do decide to sell, make sure to keep a few just in case.
Good Luck!
