I think it is a good decision to do ethereum staking if you strongly believe in it and you have ethereum that you don’t use.
I don’t think this is a good decision because you don’t know when your coins will be unlocked.
And during this time, you can, for example, sell ethereum for $ 6,000 and buy this coin, for example, for $ 2,000.
After the end of Ethereum mining, users will be able to manage their coins, then you can think about such an investment.
