Shall I stake? I will hold anyway.

Hi,

I just read a couple of articles about staking but still I am not sure about the risks. Lets say I have 2 eth that I won’t sell in the next years anyway, shall I stake then?

I want to keep the ETH in my own wallet, is there any risk losing my eth when staking? This is done via a smart contract from a staking pool, correct?

Can I still use the ETH address then, just not the staked ETH amount?

Thank you!
