How is the SOPH kimchi premium calculated?
The SOPH KRW price on Upbit or Bithumb is divided by the Korean USDT price in won (₩1,361.6 on Upbit now) and compared with the SOPH price on Binance ($0.001870, spot): premium = KRW price ÷ USDT/KRW ÷ Binance price − 1. A venue counts only when it traded at least ₩500.0M of SOPH in the last 24 hours.
Can you arbitrage the SOPH 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 SOPH deposits or withdrawals, and the premium can close before a transfer lands. Nothing here is financial advice.
