Mining on Mobile hasn't been done but there is other project that try as well do this thing, no one heard about it here because is on penny stock in Poland, on New Connect - company name BitEvil - EraCoin. It's a bankster version of Electroneum.
Will Electroneum be successful? Hard to say, no one did this before, and when I read first time Etherum thread for me was so futuristic I didn't even follow that project and look where is today...
I will wait until Electroneum hits exchanges and if price drop to floor I may buy some. I burn myself with super hyped Monetha ICO and now must wait (800$ loss)
