What you get with HTX referral code ku5k5
Using referral code ku5k5 when creating your HTX account activates a welcome bonus package for new users. The exact bonus composition — which includes trading fee vouchers, deposit match rewards, and futures trial funds — is structured around a series of tasks you complete after registration. The more activity you complete in your first weeks, the larger the total reward you can claim.
Beyond the one-time welcome bonus, trading on HTX with an account registered via a referral code gives you access to fee structures and promotional rates that are not available to accounts created without a code. HTX's referral program is designed to reward both the person who shares the code and the new user who applies it — giving you a structural advantage over registering without any code at all.
Fee discounts for referral registrations
HTX's standard spot trading fee is 0.2% for both makers and takers at the base tier. Users who register via a referral code are typically eligible for promotional discounts that reduce this rate, particularly during the first weeks of account activity. VIP tiers based on 30-day trading volume provide further reductions — heavy traders who reach higher volume thresholds can see their fees drop substantially below the standard rate.
Why the code must be applied at registration
Like most centralized exchanges, HTX links referral relationships to your account at the moment of creation. The ku5k5 code cannot be applied retroactively to an account that was created without it. If you already have an HTX or legacy Huobi account and want to use the bonus, you would need to create a fresh account with the referral code — which is only possible if you have not previously held an account on the platform.
Vouchers are not withdrawable cash
Welcome bonus vouchers issued by HTX are trading credits, not free cash you can withdraw to a bank or wallet. They function as fee offsets — reducing the commissions you pay on trades — or as small funded trial positions in the futures market. Any profits generated from trial positions can typically be withdrawn; the voucher principal cannot. Read the specific terms attached to each bonus task carefully before activating, as vouchers often carry expiry dates of 7–30 days from issuance.
How to apply the HTX referral code — 4 steps
-
Open the referral link Navigate to htx.com/invite/en-us/1f?invite_code=ku5k5. The registration form will open with ku5k5 pre-filled in the invite code field. Verify the code is present before clicking the registration button. Enter your email address, set a strong password, and confirm your email address via the verification link HTX sends to your inbox within a few minutes of registration.
-
Complete identity verification (KYC) HTX requires Know Your Customer verification to unlock full trading capabilities, higher withdrawal limits, and the welcome bonus program. After logging in for the first time, navigate to the Identity Verification section in your account settings. Upload a government-issued photo ID — passport, national identity card, or driver's license — and complete the selfie liveness check. Most verifications are approved within minutes, though peak verification periods may extend processing to several hours.
-
Make your first deposit Fund your HTX account by transferring cryptocurrency from an external wallet, purchasing with a credit or debit card, or using a supported bank transfer method in your region. Even a small initial deposit is enough to start exploring the platform. Check your bonus task dashboard for the specific deposit thresholds that unlock the higher-value welcome rewards. The first deposit typically triggers the first tier of tasks immediately.
-
Complete bonus tasks and start trading Once your account is funded, navigate to the Rewards or Bonus section in your HTX dashboard to view your active tasks. Each milestone — first spot trade, reaching a deposit threshold, executing a futures position — releases a corresponding reward. Your fee discount activates on your very first trade and applies automatically to every subsequent order without any manual steps required. Work through the tasks at whatever pace suits you, but note that voucher activation windows are time-limited once issued.

Register on HTX — use code ku5k5HTX fee structure
HTX uses a tiered fee schedule based on your 30-day trading volume and holdings of HT (Huobi Token, now used on HTX). The standard base fee for new users is 0.2% for both spot maker and taker orders. Referral registrations may receive promotional rate reductions on top of these base fees, and volume-based VIP tiers reduce rates further for active traders.
| Market | Standard fee | With referral (ku5k5) | VIP 1 (30d vol $5M+) |
|---|---|---|---|
| Spot maker | 0.200% | Discounted | 0.100% |
| Spot taker | 0.200% | Discounted | 0.100% |
| Futures maker (USDT-M) | 0.020% | Discounted | 0.016% |
| Futures taker (USDT-M) | 0.040% | Discounted | 0.032% |
| Coin-margined maker | 0.015% | Discounted | 0.012% |
| Coin-margined taker | 0.050% | Discounted | 0.040% |
HTX's futures fees are competitive with the global market standard and significantly lower than the spot base fee. High-frequency traders and algorithmic strategies targeting the futures market will find HTX's derivatives cost structure particularly attractive once VIP status is achieved through volume.
Annual savings by spot trading volume
The table below illustrates how even a modest reduction from the 0.2% base fee delivers meaningful annual savings for active spot traders.
| Monthly volume | Fees at 0.20% | Fees at 0.10% (VIP 1) | Annual savings |
|---|---|---|---|
| $10,000 | $240 | $120 | $120 |
| $50,000 | $1,200 | $600 | $600 |
| $100,000 | $2,400 | $1,200 | $1,200 |
| $500,000 | $12,000 | $6,000 | $6,000 |
Reaching VIP status requires sustained monthly volume but delivers the largest structural fee reduction available on HTX. For traders who are already active across multiple exchanges, consolidating volume on HTX to reach a VIP tier can produce substantial fee savings versus trading at the standard 0.2% rate.
From Huobi to HTX: the full history and rebrand
Understanding how HTX came to be requires tracing a decade of crypto exchange history — from one of the industry's earliest and most important platforms to its modern reincarnation under new ownership.
Huobi's founding in 2013
Huobi was founded in September 2013 by Leon Li in Beijing, China, making it one of the oldest continuously operating cryptocurrency exchanges in existence. It launched just two years after Bitcoin had become a phenomenon in Chinese technology circles, at a time when the Chinese crypto market was growing explosively. Within its first year, Huobi had become one of the top two exchanges by Bitcoin trading volume globally — competing directly with OKCoin and Bitfinex for dominance.
Huobi's early success was built on a combination of zero-fee trading (Huobi charged no transaction fees for the first several years, monetizing through other means), deep liquidity in BTC/CNY pairs, and an interface well-suited to Chinese retail traders. The exchange attracted a significant retail trading base in China during the 2013–2017 bull cycle.
China's 2017 crackdown and Huobi's global pivot
In September 2017, China's central bank banned cryptocurrency exchanges from operating in the country, forcing Huobi and its main domestic competitors — OKCoin and Binance, which had also been operating from China — to shut down Chinese operations or relocate. Huobi chose relocation, establishing offices in Singapore and expanding its "Huobi Global" brand to serve international users through huobi.com.
The transition proved successful. Huobi Global grew rapidly during the 2017–2018 bull run, listing hundreds of altcoins and expanding its product suite to include futures trading, margin, and Huobi Earn. The company launched the Huobi Token (HT) in early 2018 as an exchange utility token — similar to Binance's BNB — designed to provide fee discounts and governance rights to holders.
The Justin Sun acquisition in 2022
In late 2022, Justin Sun — the founder of the Tron blockchain and a highly public figure in crypto — acquired a significant ownership stake in Huobi Global through an arrangement with the founding shareholders. The acquisition came at a tumultuous time for the industry: FTX had just collapsed, trust in centralized exchanges was at a historic low, and several other platforms were experiencing bank runs. Huobi itself saw significant outflows in the weeks following the announcement of Sun's involvement.
Sun moved quickly to restructure the exchange. He became an active public spokesperson for the platform, made a series of marketing-oriented announcements, and initiated a leadership and staff restructuring that saw significant headcount reductions. The exchange continued to operate throughout the transition, maintaining user withdrawals and trading activity without interruption — an important distinction from the FTX crisis that was unfolding simultaneously.
The 2023 rebrand to HTX
In September 2023, to coincide with the exchange's tenth anniversary, Huobi Global officially rebranded as HTX. The name HTX was presented as standing for "Huobi Tron eXchange" — a nod to the Tron ecosystem Sun controls — though the exact meaning was presented somewhat ambiguously in official communications. The domain moved from huobi.com to htx.com, and the exchange's visual identity, app, and all user-facing materials were updated accordingly.
For existing users, the rebrand was largely seamless. Account balances, trading history, open positions, and 2FA settings all transferred automatically. Users simply updated their bookmarks and login habits. The Huobi Token (HT) was not replaced, though there were communications about how it would interact with Tron ecosystem tokens going forward.
HTX today
HTX in 2026 is a mature, mid-to-large tier centralized exchange with deep liquidity in major pairs, over 500 spot trading markets, a full futures suite, and an earn product range. It retains a strong user base in Southeast Asia and among traders who have used the platform since the Huobi era. The platform's longevity — over a decade of continuous operation — gives it a track record that newer exchanges cannot match, even if its daily volume sits below the top-tier leaders Binance and OKX.
HTX vs Binance and OKX: direct comparison
HTX competes primarily with Binance, OKX, and Bybit for active traders seeking deep liquidity, broad market selection, and competitive fee structures. The comparison below covers the dimensions that matter most for choosing between platforms.
| Feature | HTX (ku5k5) | Binance | OKX |
|---|---|---|---|
| Founded | 2013 (as Huobi) | 2017 | 2017 |
| Spot maker fee (base) | 0.200% | 0.100% | 0.080% |
| Spot taker fee (base) | 0.200% | 0.100% | 0.100% |
| Futures taker (USDT-M) | 0.040% | 0.040% | 0.050% |
| Spot markets | 500+ | 600+ | 500+ |
| Daily spot volume | $1–3B | $50B+ | $8B+ |
| Tron (TRX) liquidity | Excellent | Good | Good |
| Operating history | 13+ years | 9 years | 9 years |
| US availability | No | No | No |
| Referral bonus (ku5k5) | Big bonus | Up to $600 | Up to $10K |
Where HTX has an edge
HTX's primary advantages are its operating history and its Tron ecosystem depth. No exchange has been running continuously for longer than HTX (formerly Huobi) among the current major platforms — this matters for traders who value institutional memory and proven resilience through market cycles. For traders with significant TRX, USDD, or other Tron-ecosystem assets, HTX offers the deepest liquidity and the most seamless experience, given Justin Sun's direct involvement with both the exchange and the Tron protocol.
Where Binance and OKX have an edge
Binance leads on raw volume, market breadth, and base fee rates. Its 0.1% standard spot fee is half of HTX's 0.2% base, making it significantly cheaper for traders who have not yet reached VIP status through volume. Binance also lists more assets and has higher liquidity across mid- and small-cap pairs. OKX's competitive advantages include its more sophisticated derivatives suite, strong web3 wallet integration, and a slightly better base maker fee of 0.08%. For traders who are volume-sensitive and do not have a specific reason to prefer HTX, Binance or OKX will typically be the more cost-efficient choice at standard fee tiers.
The case for using HTX alongside another exchange
Many active traders run accounts on multiple exchanges simultaneously. HTX makes sense as a secondary or tertiary exchange for traders who want access to its unique TRX/USDD liquidity, who want exposure to assets listed there that are not available elsewhere, or who are running cross-exchange arbitrage strategies that require multiple order books. The welcome bonus from ku5k5 provides an initial trading credit that effectively subsidizes the cost of setting up a second exchange account.
Available markets: 500+ spot, futures, and earn
HTX's trading platform covers a broad range of asset classes and product types, making it a comprehensive venue for traders who want to access both spot and derivatives markets from a single account.
Spot trading
HTX lists over 500 active spot trading pairs, with the majority denominated in USDT. Core pairs include BTC/USDT, ETH/USDT, TRX/USDT, XRP/USDT, SOL/USDT, DOGE/USDT, and a wide range of mid-cap and emerging altcoins. The exchange adds new listings regularly, often including tokens that are gaining traction in DeFi or have strong Tron ecosystem relevance. Order types available include market, limit, stop-limit, and trailing stop orders, covering the needs of both casual and systematic traders.
USDT-margined perpetual contracts
HTX's futures platform offers USDT-margined perpetual contracts on Bitcoin, Ethereum, Tron, and dozens of other tokens. Leverage is available up to 200x on BTC/USDT, with scaled maximums on lower-liquidity contracts. The perpetual contract mechanism uses a funding rate to keep contract prices tethered to spot prices — traders who are long pay the funding rate to short holders when the rate is positive, and vice versa. HTX's funding rate data is publicly available in the platform's data dashboard.
Coin-margined and delivery futures
For traders who prefer to hold collateral in BTC or ETH rather than stablecoins, HTX offers coin-margined (inverse) futures — both perpetual and quarterly delivery contracts. Coin-margined contracts settle in the underlying asset, meaning profits and losses are denominated in BTC or ETH. This structure is preferred by traders with strong directional conviction who want to maintain their base asset exposure while still trading futures.
HTX Earn
HTX's earn suite includes flexible savings (deposit assets and earn daily interest with no lock-up period), fixed-term savings (higher yields for committing assets for 7, 30, 90, or 180 days), and dual-currency investment products. The earn products are denominated in USDT, BTC, ETH, TRX, and a selection of major altcoins. Rates vary with market conditions and are updated regularly in the Earn section of the HTX platform.
Tron ecosystem depth
Given Justin Sun's dual role as HTX's major shareholder and Tron's founder, HTX has uniquely deep liquidity in the Tron ecosystem. TRX/USDT is among the highest-volume pairs on the exchange, and HTX was one of the first major exchanges to list USDD — Tron's algorithmic stablecoin. For traders or institutions with large TRX positions, HTX consistently offers tighter spreads and deeper order books than competing venues.
About HTX
HTX is a centralized cryptocurrency exchange with roots stretching back to 2013, when it was founded as Huobi in Beijing by Leon Li. It is one of the oldest continuously operating crypto exchange platforms in the world, having survived the 2014 Mt. Gox collapse, the 2017 Chinese exchange ban, the 2018–2019 bear market, and the 2022 industry crisis that brought down FTX and dozens of smaller platforms.
The exchange rebranded from Huobi to HTX in 2023 following Justin Sun's acquisition of a controlling stake. Sun is the founder of the Tron blockchain, a prominent and controversial figure in crypto known for aggressive promotion and large-scale ecosystem investment. Under his stewardship, HTX has refocused on Tron ecosystem integration, aggressive welcome bonus programs, and expansion into new geographic markets where alternative exchanges face regulatory hurdles.
HTX processes billions of dollars in daily trading volume across spot and derivatives markets, employs several hundred staff globally, and maintains offices across Asia and Europe. The platform supports over 50 fiat deposit methods depending on your region, making it accessible to users who cannot easily access crypto via traditional banking in their home country.
HTX's product team has continued to ship new features under the rebranded identity: improved mobile trading interfaces, deeper derivatives analytics, and enhanced earn product structures. The underlying trading engine and custody infrastructure were built over a decade and handle institutional-grade order flow, contributing to the exchange's reputation for reliability and uptime even during volatile market conditions.
