Is it risky to stake with Lido?

Hello, I'm considering staking with Lido, but I'm not sure if it's a risky move. Could you please explain to me the potential risks involved in staking with this platform? I've heard about the smart contracts and the liquid staking concept, but I'm still a bit uneasy about the security aspect. Could you also tell me about Lido's reputation in the industry and any previous instances of hacks or security breaches? Additionally, I'm interested in understanding the returns offered by staking with Lido and how they compare to other staking platforms. Thank you for your time and assistance.
