How do you make money with Ethereum proof of stake?

So, how exactly does one make money with Ethereum's proof of stake system? Is it simply by holding Ether and staking it, or are there other strategies involved? Are there any risks associated with staking, and if so, how can they be mitigated? Additionally, how does the profitability of staking compare to other forms of cryptocurrency investment, such as mining or trading? I'm eager to learn more about this innovative system and how it can potentially generate returns for investors.
