How many ETH do I need to stake?

I'm quite new to the crypto world and staking seems like an intriguing opportunity to earn passive income. Could you please advise me on how many ETH I should stake? I've heard varying opinions on this, with some saying it's better to stake a larger amount to maximize returns, while others caution against staking too much in case of any unexpected market movements. Given my current holdings and risk tolerance, what would be a reasonable amount to stake? Would staking a smaller amount still be profitable, or should I aim for a larger stake to make it worthwhile?
