Where to safely stake ETH?

As a crypto enthusiast, I'm constantly on the lookout for ways to grow my portfolio. With Ethereum's (ETH) popularity soaring, I'm particularly interested in staking my ETH to earn rewards. But, with the ever-evolving crypto landscape, I'm not sure where to safely stake my ETH. Could you please elaborate on the key considerations I should make while selecting a staking platform? I'm specifically looking for platforms that offer high security, ease of use, and a decent annual percentage yield (APY). Additionally, are there any regulatory concerns or risks I should be aware of before making this decision? Your guidance would be invaluable in helping me navigate this process.
