I think electroneum price will rise, maybe like in the next 1-2 years. The team behind it is doing a very good job and keep inovating it. 1$ per electroneum is very possible I think. But yeah I believe there is no altcoin at the moment that capable to beat bitcoin.. At least not for now and not anytime soon.
I agree that electroneum has a solid team and good ideas behind the project, but for now they obviously have some problems with this mobile mining thing as number of coins is not defined and the price has been going down since the release. Maybe it will get to 1$ some time later but I guess bitcoin will go up a lot too then, so electroneum will still not surpass, but perhaps we'll see it in the top 10 if the game attracts enough people.
