Mega Coupons Feature Upgrade
Published on: 2026/07/17 15:25Last Update: 2026/07/17 15:25

Dear CoinW Users,

 

To improve asset allocation efficiency and enhance user experience, CoinW has upgraded the Mega Coupons system. Mega Coupons can now be used more effectively to offset trading fees, funding fees, and trading losses in futures trading.

 

1. What Are Mega Coupons

 

Mega Coupons are trading vouchers designed for futures trading. They have a specific usage scope and validity period. Mega coupon funds cannot be withdrawn directly, but can be applied in futures trading, such as offsetting trading fees.

 

For more details, click here to view “Mega Coupon Usage”.

 

2. Key Upgrades

 

2.1 Issuance and Usage

 

Upgraded Mega Coupons are issued to the Rewards Hub and will not take effect in the futures account until claimed.

To use Mega Coupons, users must firstly claim them from the Rewards Hub to their futures account, ensuring clear separation between issuance and usage.

All coupon merging operations such as proportion-based merging, are performed only in the Rewards Hub, keeping fund management and usage separate.

 

2.2 Dynamic Claiming Rules

 

The claimable amount of Mega Coupons is calculated based on the futures account balance. Coupons can be claimed in following three ways:

 

1. Automatic Claiming: The system will automatically claim the coupon daily at approximately 00:00, 08:00, and 16:00 based on users’ futures account balances.

2. Manual Claiming: Users can manually claim the coupon, with the amount calculated based on the current futures account balance.

3. Transfer-Triggered Claiming: When users are transferring funds to their futures accounts, the system will calculate the claimable Mega Coupon amount based on their futures account balances and automatically apply the maximum ratio. If a futures account already holds Mega Coupons, the existing ratio will be applied.

 

2.3 Return Mechanism

 

If Mega Coupons no longer meet the usage conditions, the system will automatically return them in the following scenarios:

 

  • Expiry: Upon expiration, if there’re no open positions or orders using the Mega Coupon funds, the coupons will be returned to the Rewards Hub.

  • Transfer-Out: When users are transferring funds out from their futures accounts to other accounts, the system will calculate the Mega Coupon amount to return based on users’ futures account balance and usage ratio, and return them to the Rewards Hub.

 

2.4 Coupon Ratio Adjustment

 

Only one coupon ratio can be applied per futures account at any given time.

  • If there are no positions or orders opened using Mega Coupon funds, users can switch to a different ratio. The system will automatically return the current Mega Coupons and recalculate the claimable amount under the new ratio.

  • If Mega Coupons are in use or there’re open positions or orders opened using Mega Coupon funds, users cannot switch the ratio. For more details, please refer to the tips displayed on the Mega Coupon page.

 

3. Claiming and Transfer Rules

 

3.1 Calculation Logic

 

The system calculates the claimable Mega Coupon amount based on users’ futures account balance and coupon ratio when conditions are met:

 

  • Claimable Mega Coupon = Futures Account Balance / (1 - Ratio) × Ratio

  • Additional Transfer In = Futures Account Balance / (1 - Ratio) × Ratio - Existing Mega Coupon Amount

  • Additional Transfer Out = Existing Mega Coupon Amount - Futures Account Balance / (1 - Ratio) × Ratio

 

3.2 Example

 

Assume Account A holds an 80% Mega Coupon worth 50 USDT in the Rewards Hub, valid until 2026/12/31 23:59:59.
