The South Korean won is written KRW or ₩. Korea Tourism Organization's practical guide explains currency exchange and notes broad credit-card acceptance at many businesses. For account comparisons, the currency code is clearer than the symbol because the North Korean won can share the same sign. [2] [1]

A local KRW budget is easiest to track when deposits, balances and withdrawals are expressed in KRW. Where an account uses USD or another currency, compare the full converted debit with the credit received. Keep currency conversion separate from odds calculation: a winning price and an exchange-rate change are different sources of a changed balance.
