Personally, I do not believe in mobile mining - maybe they will prove me wrong. Nevertheless, I think it is a buzzword. It won't be economically beneficial enough. My phone is getting hot and has significantly lower battery time even without mining anything on it.
What is more, after reading the whitepaper my impression is that there is a lot of nice formatting and marketing talk. Yet, there is very very little real content there and no description of valid business model.
In current state of the project, those are a No-Go for me.
Well there's more than that. There's also getting electroneum integrated with mobile apps as payment method for special features and being able to be transferable from one app to the other incentivizing developers to integrate this coin. Also something with gambling but i'm not aware of the details on that.
