Staking on Coinbase – withdraw anytime?

Basically I have a decent sized mining operation of 3000 series nvidia cards that are mostly paid off. I want to start holding eth instead since it is going to become a deflationary asset with the London hardfork, which will obviously increase its price if all things remain the same. However, I do believe we are on the verge of another economic recession that I guess to be 6-18 months away (just my personal opinion based on a lot of things). So I want the flexibility of staking without having to lock in the eth until 2.0.
