please let me know how to convert bticoin and KRW to bitcoin
if you click on the 'BTC' button on the right side of BTC quantity from the purchase/sales page to use the simple calculator
please refer to the following formula for the conversion of KRW and bitcoin
KRW = Possesing BTC X Price per Bitcoin
BTC = Possesing KRW / Price per Bitcoin
ex) if the market price of 1 BTC is 300 thousand KRW
15 X 300,000 = 450,000KRW if you possess 15BTC
600,000/300,000 = 2BTC if you possess 600,000 KRW
