Is Coinbase allowed in South Korea?

Could you please enlighten me on the legality of Coinbase in South Korea? I've been hearing conflicting reports about whether or not it's permissible to use this cryptocurrency exchange in the country. Would it be possible for you to clarify the situation for me? I'm particularly interested in knowing if there are any specific regulations or licenses required for operating such a service in South Korea. Additionally, could you also mention any potential risks or limitations that users in South Korea might face when using Coinbase? Thank you in advance for your assistance.
