How much is tax in Korea for foreigners?

Excuse me, I am a foreigner who has recently invested in cryptocurrencies and is now considering relocating to Korea. I would like to know the tax regulations regarding cryptocurrencies for foreigners in Korea. Specifically, how much tax am I expected to pay on any income generated from cryptocurrency investments, trading, or mining activities in Korea? Also, are there any specific tax incentives or exemptions available for foreign investors in the field of cryptocurrency? Thank you for your time and assistance.
