A.Foreign exchange margin trading involves turning a profit by exchanging currency like Japanese yen or U.S. dollars.

1 BTC = buy for 350,000 yen

News of the bitcoin price hike

Sell at 1 BTC = 400,000 yen
(Happy )

FX is short for “foreign exchange.”

Sometimes 1 BTC can be traded for ¥400,000, and sometimes it can be traded for ¥350,000. If 1 BTC bought for ¥350,000 is converted back to Japanese yen when the BTC price is raised to ¥400,000, you’ll make ¥50,000 more.

A.A margin is the initial money used for security in a leverage trade.


売買希望金額 100,000円 x 数量 2btc x 証拠金率 50% = 必要証拠金 100,000円

A.Offsetting is the closing method of simply recording the result of a transaction without actually performing an exchange of currency.

With AirFX at Zaif, currency is not actually transferred.


A.Aside from the money deposited as a margin, there are no other losses.

We avoid losses in AirFX at Zaif through forcible settlements against the positions of customers who are gaining a profit when you incur losses that are greater than the margin due to sudden fluctuations in market price
Despite the possibility of a forced settlement regardless of profit generated, there is a mechanism to assist customers even when they are subject to a loss. This mechanism makes it unnecessary for customers to pay more than what they had deposited (known as additional cover).
However, this mechanism has been adopted for AirFX only. Please note that there is a possibility that you may end up in the negative due with other leverage trading, such as credit trading, after closing a trade on AirFX.

A.Loss-cut is a forced settlement in the event that a loss has become too great.

In AirFX, a loss-cut is applied if the margin rate falls below 30% to prevent a loss from expanding. When such a loss occurs, there is a forced settlement of the held position.
The risks associated with a loss-cut naturally increase with severe price fluctuations, especially when trading with high leverage. Especially in circumstances when the spread is large or when the market price is fluctuating wildly, there is a likelihood of becoming subject to immediate loss-cutting and bearing unexpected losses, so please bear this fully in mind when trading.
In addition, the loss-cutting margin rate is calculated in consideration of the ordering conditions on the board, instead of being decided on the final trading price.

A.スワップポイントとは、Orderbook tradingとAirFX間における、同一暗号資産の差額調整分のことです。

AirFXはOrderbook tradingではないため、Zaif内にて現物で取引されているビットコインの価格と差が生じる可能性があります。
In order to reduce deviation as much as possible, fees are generated at fixed time intervals each day among users’ positions. These fees are called “swap points.”

Swap points are paid in terms of positions attempting to expand a deviation against positions trying to reduce a deviation.
The swap point is designed to be higher the larger the deviation gets, but will not appear if there is no deviation.

A.There is generally no processing fee for trading. However, there is a daily fee and the fees for swap points.

How to use the Limit Price function

Limit Price is a mechanism that executes a reverse trade on Bitcoin that you have bought or sold at a time when the designated amount of money is exceeded or falls short. In other words, the mechanism makes it possible to secure generated profit at a fixed interval when the market moves in the way that you anticipated.


1.Purchase 1 BTC at ¥15,000 (with limit set to ¥0.55 million).

2.If BTC reaches ¥0.55 million, sell the 1 BTC

3.The deal is confirmed, securing a profit of ¥50,000 in total.

However, it is possible to incur an opportunity loss in the event that the market experiences further growth.

How to use the Stop Price function

Loss-cuts are an essential risk management tool for minimizing your losses each time you trade.

A loss-cut is an action that closes a position and closes its losses to prevent further losses when the market price continues to shift unfavorably.

Setting a stop-loss enables you to close an order without limit when the security reaches a price designated by the market value to automatically cut losses on a held position.

However, if there are any swap fees, they will be collected separately.
