BYDFi 50% Fee Rebate for Korea and Japan: How the Permanent Rebate Link Works (2026)

By Dana Kovac · Published 2026-10-20 · Independent review — not affiliated with any exchange

Bottom line

BYDFi offers a region-specific sign-up link for residents of South Korea and Japan. Accounts created through it receive a permanent 50% rebate on trading fees, which effectively halves the fee rate paid. Users in other countries cannot claim the rebate even if they register through the same link.

Most exchange referral links hand you a one-time welcome bonus. BYDFi’s 50REBATE link is different in two ways: the benefit is a rebate on fees rather than a bonus, and it is restricted to two countries. If you live in South Korea or Japan and are comparing futures exchanges on cost, it changes the math, so it is worth understanding exactly what it does before you register.

Register through the link here: BYDFi 50% fee rebate (Korea and Japan residents). Everything below explains what that link does and who it is for.

What the 50% rebate is

A fee rebate returns part of the fee you already paid. With the 50REBATE link, half of your trading fees come back to the account. In practice that means the rate you effectively pay is half the posted rate.

Using BYDFi’s published standard-tier numbers as the reference point (see our BYDFi fees explained guide for the full schedule):

Fee typePosted rateEffective rate after 50% rebate
Futures maker0.02%0.01%
Futures taker0.06%0.03%
Spot0.10%0.05%

These are illustrative figures based on the standard tier shown on BYDFi’s public fee schedule. Your own tier may differ, and the rebate halves whatever you actually pay, so higher-volume accounts see a proportionally larger absolute saving.

The important word is permanent. This is not a campaign with a start and end date. The rebate stays attached to the account for as long as the program runs, which separates it from BYDFi’s volume-based promotions like USDT Trade & Earn that pay out for a defined window and then close.

Who can claim it

Only residents of South Korea and Japan.

The link is a regional offer. Anyone can click it and the registration form will work from anywhere, but the rebate is only applied to accounts that BYDFi identifies as Korean or Japanese residents. If you are in another country, you can still open a BYDFi account through a general link such as the one on our BYDFi review, but the 50% rebate will not be attached. There is no workaround for that, and this site does not suggest one.

Two legal notes that matter more than the discount:

How to register so the rebate is applied

  1. Open the 50REBATE registration link before creating any BYDFi account. The rebate binds at sign-up and cannot be added to an existing account.
  2. Complete registration with your email or phone number as usual.
  3. After logging in, check the fee or rewards section of your account. The rebate terms shown there are the authoritative version; a third-party article, including this one, is only a summary.
  4. Trade normally. The rebate is calculated on fees you actually pay, so it scales with your activity rather than requiring a separate claim for each trade.

If the rebate does not appear in your account after registration, the most common cause is a registration that BYDFi did not associate with Korea or Japan. Contact BYDFi support through the official in-app channel; do not rely on messages from anyone who contacts you first claiming to be support.

When the rebate matters and when it does not

The rebate is most useful for active futures traders, where fees are a visible line item every day. A taker who pays 0.06% on each side of a position is effectively paying 0.03% with the rebate, which over a month of frequent trading is a larger saving than most one-time welcome bonuses.

It matters less if you trade rarely, hold spot positions for months, or care mostly about listing breadth. In those cases, compare BYDFi on the rest of its feature set in our exchange rankings rather than on the rebate alone.

Finally, a rebate halves your cost; it does not halve your risk. Leverage on BYDFi runs high, and a cheaper fee on a losing position is still a losing position. Decide on the exchange first, then take the rebate if you qualify, not the other way around.

Frequently asked questions

What does the BYDFi 50% fee rebate actually do?

Half of the trading fees you pay on BYDFi are returned to you as a rebate. On BYDFi's published standard-tier futures rates of 0.02% maker and 0.06% taker, the effective cost after the rebate works out to 0.01% and 0.03%. The rebate is tied to the account created through the regional link, not to a one-off promotion.

Who is eligible for the BYDFi 50REBATE link?

Only residents of South Korea and Japan. The link is region-specific: if your account is registered from another country, the rebate is not applied even though the registration itself goes through. Eligibility is determined by BYDFi's own checks, not by this site.

Is the 50% rebate permanent or a limited-time campaign?

It is positioned as permanent for eligible accounts, not as a campaign with an end date. That is the main difference from BYDFi's volume campaigns such as USDT Trade & Earn, which run for fixed periods. Program terms can still be revised by the exchange, so check the rebate section in your account for the current wording.

Can I add the rebate to an existing BYDFi account?

No. The rebate is attached at registration. An account that already exists cannot be re-linked to the 50REBATE code afterward, so the link only makes sense before you create the account.

Is BYDFi licensed in Korea or Japan?

No. BYDFi is an overseas exchange. It is not a Korean FIU-registered virtual asset service provider and it is not registered with Japan's Financial Services Agency. Residents of both countries are responsible for checking the legal status of using an overseas platform before depositing. This article does not recommend any method of bypassing local access restrictions.

Does the rebate also apply to spot trading fees?

The rebate is described as a trading-fee rebate without an instrument carve-out, so spot fees are expected to be covered as well. Because fee tiers and product coverage change, confirm the exact scope in your BYDFi account's fee or rebate page after registering rather than relying on a third-party summary.
