Can I get tax refund in Korea?

Excuse me, I am a foreigner visiting Korea and I have a question regarding taxes. I understand that in some countries, individuals can claim tax refunds for certain expenses or investments. Given that I have made some transactions in cryptocurrencies while being in Korea, I was wondering if I am eligible for any tax refund here? Could you please enlighten me about the process and requirements for claiming tax refunds in Korea, especially for crypto-related transactions? Thank you for your time and assistance.
