Cashing out crypto as a minor?

I'm a minor, and I'm getting ready to do some commission work online and planning to be paid in crypto. I would like to stay anonymous so other payment methods are out of the question. My question is, how can I exchange this crypto for us dollars? I can't have my parents do it for me because it would legally be their revenue not mine so it wouldn't qualify for the $12,500 annual unreported income available to minors. And, yes I am legally old enough to work in my state. Any ideas of how I can cash out this crypto and have it legally be my earnings?

Edit: I meant I want to anonymous from others online, not the United States government.

Edit 2: PLEASE READ THE POST BEFORE COMMENTING. I am not trying to commit tax fraud, I am trying to ensure the earnings are legally mine and not my parents. Because in the U.S, minors don't have to report their first $12,500 anually.
