How is the API3 kimchi premium calculated?
The API3 KRW price on Upbit or Bithumb is divided by the Korean USDT price in won (₩1,352.4 on Upbit now) and compared with the API3 price on Binance ($0.3491, spot): premium = KRW price ÷ USDT/KRW ÷ Binance price − 1. A venue counts only when it traded at least ₩500.0M of API3 in the last 24 hours.
Can you arbitrage the API3 kimchi premium?
Not easily. Korean exchanges take won only from verified local bank accounts and South Korea limits moving won abroad, which is why the gap can last. Transfers take time, an exchange can suspend API3 deposits or withdrawals, and the premium can close before a transfer lands. Nothing here is financial advice.
