I am sort of new to crypto, and want to earn crypto, and have questions.

I’ve watched crypto and how it has been for 2-3 years on and off and Ive wanted to start collecting crypto. I would appreciate some help with what I wrote below.

I am personally confused what crypto I should be trying to get? How I can earn “free crypto” if any? and would it be even worth it trying to use my gaming pc I haven’t used in months to be a mining machine? It’s a pretty good pc it’s just I’m not sure what is truly required to have a good mining setup or if it is worth doing.

What kinds of activities are good for earning crytpo? I feel like there is a lot of information to process.
