Is it illegal to use KuCoin?

Could you clarify the legality of using KuCoin for cryptocurrency trading? Some exchanges have faced regulatory scrutiny, so I'm wondering if there are any concerns surrounding KuCoin's operations. Are there any countries or regions where using KuCoin would be considered illegal? Additionally, does KuCoin comply with anti-money laundering and know-your-customer regulations to ensure users' safety and security? I'd appreciate any insight you can provide on the matter.
