Start mining now?

Hi guys,

I've been looking into ETH mining. Do you think it's worth getting into now with ETH working on POS? I figure once mining eventually stops, I could move to XMR or something.

Should I sell ETH to do this? I have the money in crypto to be able to purchase everything for a moderate rig. I'm not normally for selling / spending crypto but I see this as more of a crypto investment, so I could be okay with this.

Any tips for a beginner?
