Mining on an android was easy before peoples started using huge devices to mine bitcoin and other alternative coins.Mining bitcoin is now difficult it needs a lot of hash power to run or to mine .So peoples started using warehouses to mine in a large amount of hash power. Mining on android using cpu is not profitable which is around a penny per year so it waste your time and damage your phone . Still wanting to mine bitcoin and other currencies ? then you should buy miners and start mining by joining pools. But if you want to mine by using your mobile device then you should use neoneonminer apk you won't get it on play store since it uses your cpu and google play takes it as a treat for your device. There is also another miner which is called as miner it allows you to mine cryptos on your mobile device. You can't mine bitcoin but you can mine DOGE,BITCOIN CASH,LITECOIN etc. They use your cpu and if you use this apps frequently they could end up damaging your phone. For these and other reasons you should not use Android devices for mining purpose . And the other thing to remember is that you have to join pools which can be zergpool,zpool,nice hash etc. Also the best algorithm for mining on the apps which I mentioned above is yescrypt and the coins BCH,DOGE,LTC,DGB etc. Thanks thats for now see you soon.
