I had high hopes for Electroneum, had my rig mining ETN, bought some and even recommended it to a friend, but it's seems to have all gone a bit pear-shaped recently. The delay in making it ASIC resistant has not helped, so I've moved onto mining another coin and both me and my friend sold our ETN some time ago.
Maybe it will be more attractive in the months to come, time will tell.
How do you define "attractive"? Does a higher price make it more attractive to you? Because it should be the other way around, at least for investors (and I consider myself one).
The lower the price of any security the better, it offers a better risk/reward ratio.
If you believed in this project enough to buy somewhen in the past, you should have bought even more with the price it has reached now, not sell.
The only exception would be a downturn to the project's roadmap, but I haven't noticed anything of that sort with Electroneum.
