Home depot shopping!

Been watching your videos and I'm trying to figure out how you mine crypto.
I believe you did a video on it, so i just got to search for it, yeah i am new...
So far i see you use Gemini and Poloniex, I opened up a Coinbase account, so far no problems, but want to get some other crypto not available on Coinbase. but main question is where can i learn more about mining?
