暗号資産計算機 - 円建てトレーダー向け為替と暗号資産の計算

📱 App Overview
The Cryptocurrency Calculator is a tool exclusively for traders who place limit orders in yen at Japanese exchanges while watching the USD price on overseas charts. It instantly solves tedious exchange rate calculations and dramatically improves trading efficiency.

💡 Ideal for traders with the following problems

Even though you check the USD price on TradingView or Binance, you have to place limit orders in yen on domestic exchanges (bitFlyer, Coincheck, GMO Coin, etc.).

It's a hassle to calculate "How much should I limit order $50,000 BTC at?" every time with a calculator.

Because the exchange rate is constantly fluctuating, it's difficult to know the exact limit price.
