Noob question about Staking ETH on Coinbase

When you stake ETH for the 2.0 network that’s upcoming, I understand it becomes unavailable / locked.

My question is around it’s value. To keep it simple, I’ll just use 1 ETH in my scenario.

If i was to stake 1 ETH right now, I would earn 7.5% back on that staked ETH. My question, is if ETH were to go 10x it’s current price, does my staked ETH also increase in value 10x, or is it locked at the price i staked it at?
