如何使用「加密货币盈亏计算器」？How do I use the Crypto Profit Calculator tool?

在「加密货币盈亏计算器」中，填写「数量」、「买入价」、「卖出价」、「手续费」、「买入手续费」等参数，结果会随输入实时计算并显示在下方。In the Crypto Profit Calculator: Fill in "Quantity", "Buy price", "Sell price", "Fees", "Buy fee"; results are recalculated instantly as you type.

手续费怎么算？How are fees applied?

选「按成交额比例」时，买入手续费 = 买入数量 × 买入价 × 比例，卖出手续费 = 数量 × 卖出价 × 比例；选「固定金额」时直接加到成本、从卖出所得中扣除。收益率 = 盈亏 ÷ 含手续费的成本。滑点和网络（gas）费可以折算进固定金额。With Percent of trade value, the buy fee is quantity × buy price × rate and the sell fee is quantity × sell price × rate; with Fixed amount the fees are added to the cost and taken off the proceeds as entered. Return = P/L ÷ cost including fees. Slippage or network (gas) fees can be folded into the fixed amounts.

买入价为 0 时收益率是多少？What if the buy price is 0?

成本为 0 时收益率在数学上没有定义（相当于无穷大），页面会显示“无法计算（∞）”而不是 0%。With a cost of 0 the return is mathematically undefined (effectively infinite), so the page says so instead of showing 0%.

能举个计算实例吗？Can you show a worked example?

例如在「加密货币盈亏计算器」中填 数量 = 2，买入价 = 100，卖出价 = 150，手续费 = 不计手续费，结果区显示：成本（含买入手续费）：200.00；卖出所得（扣卖出手续费）：300.00；盈亏：100.00；收益率：50%For example, entering Quantity = 2, Buy price = 100, Sell price = 150, Fees = No fees in the Crypto Profit Calculator gives: Cost (incl. buy fee): 200.00; Proceeds (after sell fee): 300.00; P/L: 100.00; Return %: 50%
