The Kimchi Premium

South Korea is known for the "Kimchi Premium," a phenomenon where Bitcoin prices on Korean exchanges trade above global market prices, sometimes by 5-15% or more during high demand. This occurs due to capital controls and restricted arbitrage between Korean and international markets.

Important Notes for Korean Buyers

• Only Korean residents with a real-name verified Korean bank account can trade on domestic exchanges
