How do I get the most out of my Ethereum?

I brought what I could afford at the start of the year (20 Ethereum). I've been holding since but I notice people talking a lot about staking. I've been using Coinbase pro since the beginning.

I want to make the most out of what I have and don't plan on touching it for at least 2 Years. Is there anything I can do with it or is holding always better?
