Which country can t use KuCoin?

Could you please provide me with some clarification? I'm trying to understand which countries are unable to utilize the KuCoin platform. Could you specify any particular regions or nations that have restrictions or bans on accessing KuCoin? I'm interested in knowing if there are any geographical limitations that users might encounter when attempting to use this cryptocurrency exchange. Additionally, if there are any legal or regulatory reasons behind these restrictions, it would be helpful to have an overview of those as well. Thank you for your assistance in clarifying this matter.
