How safe is MEXC?

I'm considering using MEXC for my cryptocurrency trading, but I'm wondering about the safety of the platform. Can you tell me more about the security measures MEXC has in place to protect user funds and personal information? Are there any known security breaches or vulnerabilities that users should be aware of? Additionally, how does MEXC handle customer support in case of any issues or concerns? I'd appreciate any insights you can provide to help me make an informed decision.
