Staking generally has a very low difficulty because proof of work is not the main way that new coins are minted. So if you own a staking coin you can use a regular laptop to stake and just leave the wallet running.
If you want to stake a more advanced coin like ETH then you should just leave it on the exchange that supports staking and they will do it for you.
There is a certain degree of risk because you need to keep the coins on an online computer and there is some degree of risk.
Which coin do you want to stake exactly?
