Its only east if you get the hang of building a rig and setting up the algorithms along with choosing the right altcoins to mine. That means that you should have at least a good amount of technical skill before you start and you will get confused even before you start earning in crypto mining. The good thing though is that even if you don't have that technical skill you can always do the research on how to start, though lets face it many people would just want to plug the components and start the application and call it mining then end the day without even researching.
