It's worthless whatever version you get, have, and use. The fact that you have to restart the mining is ignorant. I can mine on other apps without restarting. In three days, I have made .06 cents using the app and using two phones, at the 2000h/s. Don't let anyone (YouTube Scum) tell you that you can make more hashes if you use the browse as an actual browser; it's a lie. The probability of making any real money with this app is like winning the lottery with all the winning numbers.
