I've read all the articles telling me how worthless mining with Android was. Well after a few months , I made a few thousand bytecoin, turned it into NAV coin and now I've made 20 dollars. I noticed a few months ago that because bytecoin went up in price it became harder to mine. So I took a break for a while and now I think I'm going to go back at it again. I'm running to Android boxes with octo cores, 1 Android box that might be dual core. And my phone which is about 20 Mega hash... Same as the other boxes.
