I first got started mining in 2013. I used GPU and joined up with pools.
I abandoned it and last year heard about masternodes and cloud mining etc... That is a different topic altogether. Meanwhile there is a new and hyped coin call Electroneum. This has a mobile app in which eventually you will be able to do mobile mining, but for now you can check your balances.
I will have to do a write up on how i'm currently setup to mine this. Until next time.
