Electroneum just released their mobile miner! But it isn't actually mining... The app will make you electroneum just for keeping it on. Here is how they put it: "Instead of actually using your phone’s CPU to solve complicated cryptographic problems (as is done with real mining), the app will continually monitor the available CPU power on your phone. In this way, it will determine the amount of CPU power that could have been used for mining, had the phone actually been mining. Your phone will then be issued with a hash rate (speed of mining, if you will) based on its available CPU power. ETN coins will be credited to your online wallet based on this hash rate." Kind of a no brainer, right? You can get the app from Google play (https://www.google.se/url?sa=t&source=web&rct=j&url=https://play.google.com/store/apps/developer?id=Electroneum+Ltd&hl=en&ved=2ahUKEwiGuo3ox9XZAhWKVywKHXEeA1YQFjABegQIBxAB&usg=AOvVaw2zH9a5QTjlAApjT6vM49y6). If you found this helpful, then scan the tag from the app, so I can enter the weekly competition for a chance to win 5000 ETN :-)
