What is the minimum ETH needed to stake?

Could you please elaborate on the question, "What is the minimum ETH needed to stake?" I'm curious to understand the technical requirements and financial implications of staking Ethereum. Is there a specific threshold that must be met in order to participate in staking? And how does this minimum amount affect the overall staking process and potential rewards? Additionally, are there any other considerations or factors that I should be aware of when it comes to staking Ethereum? Thank you for your assistance in clarifying this matter.
