OrangeX.com Flexible Earn APR Booster Coupon Now Live
Updated on 2026/10/23
OrangeX.com’s Flexible Earn APR Booster Coupon is now live. Use a coupon to earn additional interest on eligible Flexible Earn principal during the coupon’s validity period.

APR Booster Coupons apply to the Flexible Earn products and currencies specified on the coupon. APR Booster interest is calculated separately from the standard Flexible Earn interest and is distributed in the same batch.

Where to use it: My Rewards > Coupons, the Simple Earn- Flexible Earn homepage, the Flexible Earn subscription page, or an eligible existing Flexible Earn position.
Please note the following rules before using a APR Booster coupon:
  • APR Booster Coupons in this campaign apply only to Flexible Earn. They are not available for Fixed-Term Earn or Dual Currency products.
  • For the same user, currency, and Flexible Earn product, only one APR Booster Coupon may be used at a time during its validity period.
  • If your principal exceeds the APR Booster coupon’s maximum eligible principal, only the amount within the limit earns the boosted rate. Any excess principal continues to earn the standard Flexible Earn rate.
  • APR Booster interest is calculated in full-hour intervals. If the eligibility conditions are not met for an entire hour, no booster interest is earned for that hour. Missed interest is not credited later, and the coupon’s validity period is not extended.
  • APR Booster Coupons are non-transferable. Additional interest earned through an APR Booster Coupon is not eligible for any rebates.

The APR, minimum eligible principal, maximum eligible principal, and validity period vary by APR Booster coupon. Please refer to the APR Booster coupon and the information displayed on the platform. Daily booster interest is distributed to your Spot Account alongside standard Flexible Earn interest at 08:30 (UTC+8) the following day.

Flexible Earn APR Booster Coupon FAQ

1. What is a Flexible Earn APR Booster Coupon?

An APR Earn Booster Coupon can be applied to eligible Flexible Earn products to earn additional interest on eligible principal. APR Booster interest is calculated separately from standard Flexible Earn interest but is distributed in the same batch.

2. Which products are eligible for APR Booster Coupons?

These APR Booster coupons apply only to the Flexible Earn products and currencies specified on the coupon. They cannot be used for Fixed-Term Earn or Dual Currency products. Check the eligible products and currencies on the coupon before claiming or using it.

3. Do I need to complete KYC to claim or use an APR Booster Coupon?

Some users may claim an APR Booster Coupon without completing KYC. But, you must complete KYC verification before using the APR Booster coupon.

4. Can I transfer an APR Booster Coupon to another user?

No. APR Booster Coupons cannot be transferred to another user.

5. How do I use an APR Booster Coupon?

You can use a coupon in either of the following ways:
  • From My Rewards > Coupons: If you already have an eligible Flexible Earn position in the same currency and your principal meets the coupon’s minimum requirement, confirm the APR Booster coupon to apply it to that position. If you do not have an eligible position, or your current principal is below the minimum, the platform will direct you to the subscription page for the corresponding Flexible Earn currency.


  • Use when subscribing to Flexible Earn: On the subscription page, select a claimed APR Booster Coupon from the coupon dropdown menu. The APR Booster coupon must be eligible for the selected currency and product.
The subscription page displays only claimed APR Booster Coupons that are eligible for the selected currency and product.


6. Is there a minimum principal amount required to use an APR Booster Coupon?

Yes. Your Flexible Earn position or subscription amount must meet the minimum principal amount stated on the APR Booster coupon to earn booster interest. If, after selecting a coupon during subscription, your existing position plus the amount you are subscribing still falls below the minimum, the subscription page will prompt you to add funds or remove the coupon, and the subscription will be temporarily disabled.

7. What is the maximum eligible principal amount for booster interest?

It is the maximum amount of principal eligible to earn the APR shown on the coupon. If your principal exceeds this limit, only the amount within the limit earns booster interest. Any excess principal continues to earn the standard Flexible Earn rate.
For example, if the maximum eligible principal is 1,000 USDT and you subscribe 5,000 USDT, 1,000 USDT earns booster interest, while the remaining 4,000 USDT earns the standard Flexible Earn rate. Exceeding the limit does not affect your subscription.


8. Can I use multiple APR Booster Coupons on the same product at the same time?

No. For the same user, currency, and Flexible Earn product, only one coupon can be used until its usage period ends. This also applies if the current APR Booster coupon has reached its maximum eligible principal and the remaining eligible amount is 0. You must wait until the current APR Booster coupon’s usage period ends before using another one.

9. How is booster interest calculated?

For each hour, the eligible principal is the lower of the effective principal at the beginning and end of that hour, capped at the APR Booster coupon’s maximum eligible principal.
Hourly booster interest = Eligible principal × Booster APR ÷ 365 ÷ 24
Booster interest is earned for an hour only if all eligibility conditions are met for the entire hour: the coupon is still within its validity period, its status is active, and the effective principal meets the minimum requirement. If any condition is not met for the full hour, no booster interest is earned for that hour. It will not be credited later, carried over to another hour, or extend the coupon’s validity period.


10. When does booster interest start accruing?


  • For a new Flexible Earn subscription: Interest starts accruing at the next full hour after the subscription is successful. The first hourly interest is generated at the following full hour.
  • When applying a coupon to an existing position: Booster interest starts accruing at the next full hour after the coupon is successfully applied.
Booster interest is calculated in full-hour intervals. Periods shorter than one full hour do not earn booster interest.


11. When is booster interest distributed?

Daily booster interest is distributed alongside standard Flexible Earn interest and is expected to be credited to your Spot Account at 08:30 (UTC+8) the following day. The total interest displayed on the platform includes the booster interest, which is recorded separately from the base interest.


12. If I add principal after using a APR Booster coupon, can the additional amount also earn booster interest?

Yes. Additional principal starts accruing interest according to the standard Flexible Earn rules. Once it starts accruing, if the APR Booster coupon is still valid and the total effective principal meets the minimum requirement, eligible principal is automatically included for booster interest. You do not need to select the coupon again. The maximum eligible principal limit still applies.


13. Does a partial redemption affect booster interest?


  • If the remaining effective principal still meets the minimum requirement, booster interest can continue in subsequent eligible hours.
  • If the remaining effective principal falls below the minimum requirement, the APR Booster coupon will pause and stop generating booster interest.
  • If you redeem the entire position, the APR Booster coupon will not be voided immediately but will enter a paused state.
If you subscribe again within the coupon’s usage period and the new principal meets the minimum requirement after it starts accruing, the coupon can resume. If the new principal starts accruing after the coupon’s usage period has ended, the coupon will not resume.


14. Why didn’t I receive booster interest for certain periods?

Booster interest is calculated in full-hour intervals. No booster interest is earned for an hour if the coupon was not valid, was not active, or the effective principal did not meet the minimum requirement for the entire hour.
For example, if a coupon expires at 15:30, the 15:00–16:00 accrual period does not meet the conditions for a full hour, so no booster interest is earned for that period.


15. When will an APR Booster coupon be shown as expired?

An APR Booster coupon appears in the “Expired” section only after its validity period has ended. A claimed or used APR Booster coupon will not be moved to the “Expired” section early just because its eligible principal limit has been reached.


16. Where can I view my APR Booster coupon-related earnings?

View your earnings under Orders >Earn Order > Flexible Earn Records.
