Best Crypto Referral Codes 2026: Every Code, 20–70% Rebates

Crypto referral codes for every exchange we cover: 40–70% rebates (OKX: 20% + exclusive rewards), 2 to 3.5 times a typical 20% code. Codes, highlights and switching.

The Fee Otter referral code is FEEOTTER at most exchanges (mexc-FEEOTTER at MEXC, otter123 at WEEX, OTTER at CoinW; for Binance, sign up with referral code FEEOTTER), and with your UID bound you get 40%–70% of your fees back (OKX: 20% auto-rebate + exclusive rewards), 2 to 3.5 times a typical 20% code (checked October 2026). On 1,000 USDT of monthly fees, a typical 20% code returns 200 USDT; at Gate, WEEX, XT.COM or Ourbit you get 700 USDT. Below is what Binance, OKX, Bybit, Gate, Bitget, MEXC, Pionex, WEEX, XT.COM, HTX, CoinW, Ourbit, KuCoin, Bitfinex and BingX are each like and what to watch for.

Why the best referral code comes from a rebate platform

A referral code is worth exactly what it gives back. The exchange pays an affiliate share on every referred account; a typical KOL or personal code passes the equivalent of 20% (sometimes 25%) of your fees back to you, and the code owner keeps the rest. A rebate platform such as Fee Otter is a contracted affiliate that passes most of that share back (one layer refunded directly by the exchange, one paid by Fee Otter), which is why its codes return 40%–70% (OKX: 20% auto-rebate + exclusive rewards).

So searching for the "best referral code" really means choosing a rebate platform. Compare two things: the rate you actually get at each exchange, and whether every settlement is itemized. Per-exchange numbers: referral codes and rebate rates for each exchange; platforms compared: crypto rebate sites compared.

Fees verified on 2026-09-24 (each exchange's official fee schedule). · Methodology

Binance

Founded 2017, consistently first by futures volume, and among the broadest coverage across coins, derivatives and earn products. If you trade spot, futures and earn from one account, Binance is usually the "has everything" pick.

Its spot and futures fees are the industry standard values. Binance also lets BNB offset spot fees; the actual discount and VIP tiers are on the official fee schedule.

The rebate is the standard two-layer shape: the exchange returns 20% automatically and we add another 20%, for 40% in total. Full detail in Binance fees and rebate in full; new accounts follow the sign-up guide; if you already have a Binance account you can switch: Binance has an official rebind request flow, the most formal of the switching paths we document, steps in switching an existing account.

More on Binance: Binance vs Bitget fee rebate comparison, Binance vs Bybit fee rebate comparison, Binance vs Gate fee rebate comparison, Binance vs OKX fee rebate comparison.

OKX

Founded 2017, second by futures volume. OKX has a steady reputation among professional traders for its interface and API, and its 0.08% spot maker is the lowest among the major venues: Binance, Bybit, Bitget and Gate charge 0.10% (MEXC and Ourbit charge 0%, Pionex 0.05%).

If your strategy rests a lot of spot volume, those 2 basis points compound. Actual rates on the official fee schedule.

OKX is a 20% auto-rebate + exclusive rewards. The referral code is FEEOTTER, already built into the dedicated link; ask support about our exclusive OKX rewards and promotions. Full detail in OKX fees and rebate in full; new accounts sign-up guide; switching switching an existing account.

Bybit

Founded 2018, third by futures volume. It grew up as a derivatives venue and its futures books are deep, which is why it is home turf for a lot of futures traders.

Its futures taker fee is 0.055%, a shade above the 0.05% at Binance, OKX and Gate. Actual rates on the official fee schedule.

Bybit pays 40%, 2 times a typical 20% referral code. The referral code is FEEOTTER, built into the dedicated link. All 40% is Fee Otter's extra rebate, settled as one amount, so the Bybit column in our rate table shows a single combined figure. How settlement works is in auto-rebate vs extra rebate. Full detail in Bybit fees and rebate in full; new accounts sign-up guide; to switch, the fastest route is a new account verified with another ID document you haven't used, or a KYC transfer, see switching an existing account.

Bitget

Founded 2018. Alongside ordinary crypto perpetuals, Bitget's futures list includes tokenised US equities and commodities: our own settlement data has carried symbols like SOXL, SNDK and SKHY, plus XAU (gold). If you want crypto and equity exposure in one account, that is a real option.

Its futures taker fee is 0.06%, tied second-highest on this page with XT.COM, HTX, KuCoin and CoinW, behind WEEX's 0.08%, so Bitget's appeal is the rebate percentage and the breadth of what you can trade. Actual rates on the official fee schedule.

Bitget's spot and futures rebate percentages differ: futures pays 50% (20% auto + 30% extra) and spot is lower (see the note at the end). The referral code is FEEOTTER, built into the dedicated link. Full detail in Bitget fees and rebate in full; new accounts sign-up guide; note the 30-day cooldown when switching, see switching an existing account.

Gate

Founded 2013 (with HTX, the oldest on this page) and the fastest to list, with the widest coverage of small and new tokens. If you want to reach a new listing early, Gate is usually where it lands first.

Fees are the industry standard values; see the official fee schedule for the current schedule.

Gate pays 70% on futures (20% auto + 50% extra), tied with WEEX, XT.COM and Ourbit for the highest on this page; spot is different (see the note at the end).

MEXC

Founded 2018, known for a very wide token list and fast listings. Its list rates are among the lowest on this page (only its 0.05% spot taker is above Ourbit's 0%): spot maker 0% and taker 0.05% (BTC, ETH; most smaller pairs 0.08%); futures standard rates maker 0.01% and taker 0.04% (BTC and ETH futures are currently 0% / 0.02%, and many pairs are fee-free).

XT.COM

Founded 2018, with more than 1,000 spot pairs listed, among the widest on this page, so long-tail coins are often found only here. Its list rates sit at both extremes: spot maker and taker are 0.2%, tied with HTX as the highest on this page; futures maker 0.04% and taker 0.06%, the same taker as Bitget. Current schedule on the official fee page.

Rebate 70%, tied with Gate, WEEX and Ourbit for the highest on this page: bound through Fee Otter, XT.COM returns 60% automatically and Fee Otter adds another 10%. The referral code is FEEOTTER, built into the dedicated link. On futures the effective rate after the 70% rebate ranks fourth on this page (Gate, MEXC and Ourbit come out lower); on spot, the 0.2% list rate stays expensive, so spot is better done elsewhere. Full write-up in the XT.COM fee rebate guide; code details in XT.COM referral code; new accounts see the registration guide; switching in switching an existing account.

It returns part of the platform fees you pay on Margin Funding and Bitfinex Borrow: 6% at first, falling 0.5 percentage points every 30 days and reaching zero after 12 periods.

Bitfinex is not in this table: trading there is fee-free, and the 6% from code JF82UK9L8 applies only to Margin Funding and Bitfinex Borrow platform fees.

Which one should you pick?

  • You do a bit of everything and want one account: Binance. Broadest coverage, and the most formal switching path.
  • You rest a lot of spot volume: MEXC or Ourbit, with spot maker at 0%; among the major venues, OKX's 0.08% is the lowest.
  • Futures only, want the highest rebate: Gate. Its 70% futures rebate ties with WEEX, XT.COM and Ourbit for the highest on this page; the code FEEOTTER is built into the dedicated link.
  • Futures-first, want the top rebate and no mandatory KYC: WEEX.
  • Want the lowest futures fees: MEXC. Standard futures taker 0.04%, maker 0.01% (BTC and ETH futures currently 0% / 0.02%) and spot maker 0%. Its futures maker is the lowest on this page and its taker ties with Ourbit; rebate 60%, with the code mexc-FEEOTTER built into the dedicated link.
  • You also want tokenised US equities or gold: Bitget. Its futures list carries them.
  • You are already at home in Bybit's books: Bybit. It pays 40%.
  • You trade futures with bots: Pionex. Rebate 50% (15% exchange auto-rebate + 35% Fee Otter extra rebate).
  • Futures only, and zero-fee spot too: Ourbit. Spot fees are 0%, the futures taker is 0.04%, and the futures rebate is 70%; the code FEEOTTER can only be added at signup.

Already have an account? You can still bind

Yes. At most exchanges a referral code can only be entered at signup and cannot be changed once bound; a few allow adding one within a window after signup (Binance 30 days, MEXC 30 days, Bybit 14 days, Pionex 14 days); those windows are set by the exchanges, not by us. Once that window has passed, existing accounts go through "switching", and the path differs at every exchange: Binance has an official request flow, Bybit uses another unused ID document (fastest) or a KYC transfer, Bitget has a 30-day cooldown, Gate needs a fresh email, OKX has three methods (support if none works); MEXC allows two accounts per KYC so a new email is enough, and WEEX just needs a phone number or email never used there, with KYC optional; HTX just needs a new account registered through our link, and at Pionex you close the old account and register again right away, and at Ourbit you register again with an unused email or phone number and can trade and withdraw without KYC. The rebind rules table for every exchange sums them all up. Each section above links to that exchange's guide.

FAQ

What are the referral codes?

OKX, Bybit, Gate, Bitget, Pionex, XT.COM, HTX, Ourbit, KuCoin and BingX all use FEEOTTER; MEXC uses mexc-FEEOTTER, WEEX uses otter123 and CoinW uses OTTER. Bitfinex uses JF82UK9L8, which refunds part of its lending platform fees, not trading fees. Each code is built into that exchange's dedicated link, so you do not need to copy one. More detail is in the per-exchange referral code articles below.

What is the OKX rebate?

OKX is a 20% auto-rebate + exclusive rewards, and every table on this site shows OKX at 20%. For our exclusive OKX rewards and promotions, talk to support.

Why does Bybit show one number instead of "20% + X%"?

Because that number is the total: Bybit pays 40%, all of it Fee Otter's extra rebate. Fee Otter settles it as one amount, so the table lists a single combined figure; nothing is missing.

Can a referral code be added after signing up?

At some exchanges, yes. Binance (within 30 days of signup, before any deposit or trade), MEXC (within 30 days, self-service), Bybit (within 14 days), Pionex (within 14 days, or 72 hours if you have used bots) and BingX (before any deposit, if you have not invited anyone) allow adding a code after signup; elsewhere, and once a code is bound, it cannot be changed. Past that window, go through switching; each exchange differs, see the guide linked in its section above.

Do the rebate percentages change?

Each exchange has one rate, set by the exchange and Fee Otter, and the tables update live when a rate changes. That is why this page does not hardcode the tables; they come live from the platform.
