Is South Korea a tax free country?

I've heard rumors that South Korea is a tax-free haven for investors and cryptocurrency enthusiasts. But is that really the case? Are there no taxes on income, capital gains, or even cryptocurrency transactions in South Korea? If not, what are the tax implications for foreigners and locals alike when it comes to investing and trading in the country? And how does South Korea's tax system compare to other countries in the region and globally? I'm eager to learn more about the tax landscape in South Korea and how it may impact my investment decisions.
