If you have less than 32 ETH in your bag, you can use the staking pool service. But still be careful and smart in choosing a trusted pool, because this does not guarantee 100% security.
You can start staking and participate in supporting the launch of ETH 2.0 and get profit periodically by staking ETH here (for those who have less than 32 ETH):

https://ethereum.org/en/eth2/staking/#stake , and click on the See staking services link
I've read some of the material and I don't quite understand on what basis the ETH stake is returned. Is it a smart contract that determines when/to what address the ETH stake is paid or does the Ethereum organization decide when to release all the stakes?
Who controls the ETH addresses that my stake would be sent to?
Finally, is setting up a "validator" too difficult for a computer idiot like myself?
