Staking ETH on Coinbase and Slashing?

Can anyone please go into some of the details of the potential risk/likelihood of slashing if staking ETH on Coinbase?

It actually has me really nervous, they say that things outside of their control can risk 100% of my staked eth to get slashed????

Why would anyone want to stake if that’s the case? I wasn’t aware of this at first unfortunately.

Thanks for any and all input!
