Which Korean bank is best for foreigners?

Hello, I am a foreigner who is interested in investing in cryptocurrencies. I have heard that some Korean banks provide services related to this field. Could you please recommend a reliable bank for me? I would appreciate it if you could provide some details about the services they offer, such as account opening procedures, transaction fees, and any other relevant information. Additionally, I would like to know if there are any specific requirements or restrictions for foreigners when opening a cryptocurrency account in Korea. Thank you for your help!
