So this is by far not worth it at all but it is a good introduction to mining cryptocurrency.
I wanted to set up my 2013 MacBook Air to mine DOGE just just to go through the process of downloading and running xmrig through a pool on Unmineable.com.
As you can see I am only getting about 500 hash rate, so it is not much.
And after running xmrig for about 10 hours you can see it is not making much, but in the end I have a better understanding on how to set this up and now just need to get some better equipment (graphic cards or newer computer).
