We have gathered the most common questions so that first-time visitors can follow easily.
bitFlyer's BTC/JPY price (yen) is converted to won at the yen exchange rate. CoinGaja gets how many yen and how many won one dollar buys and calculates from both; right now 100 yen is about 848.49 KRW. So the bitFlyer Bitcoin price of ¥12,737,162 is about ₩108,073,965.
Even if the bitFlyer price stays the same, when the yen weakens against the won (the won amount per 100 yen falls), the price in won falls and the gap with Upbit grows. When the yen strengthens, the gap shrinks. So the gap on this page is the result of the coin price and the yen rate moving together.
