In the trading ecosystem of digital assets, over‑the‑counter (OTC) markets have become a crucial channel for large‑volume transactions. Compared with the 24‑hour public trading volume on exchanges, the Bitcoin trade size on OTC platforms is often several times larger, indicating that many institutions and high‑net‑worth investors prefer to execute bulk trades through brokers. Both individual traders and professional firms select trusted OTC brokers, while small‑ and medium‑size participants frequently encounter difficulties in finding reliable counterparties. Below, we focus on Huobi OTC (referred to as “Huobi” in the original text), outlining its positioning and step‑by‑step usage to help you quickly get started with Huobi’s off‑exchange trading services.

Starting from the core needs of OTC trading, we systematically review Huobi OTC’s functional positioning, unified account system, low‑fee structure, and security guarantees, helping newcomers get up to speed while avoiding common risks. Keep reading, and you will master the essential steps for completing large‑scale digital‑asset trades on the Huobi platform.
Benefits of Huobi OTC
Huobi Group operates its own dedicated OTC platform that offers a full suite of services. The advantages are primarily reflected in three areas:
- Unified Account System
Once you complete identity verification on the global Huobi site, the same username and password can be used interchangeably across the Huobi Global website, Huobi NEXT, and Huobi OTC. You no longer need to open separate accounts for each service. The entire registration and multi‑platform activation process typically takes no more than ten minutes, and moving tokens between platforms does not incur additional transfer fees.
- Low‑Fee Structure
When you convert your fiat currency into major cryptocurrencies such as Bitcoin (BTC), Ethereum (ETH) or USDT, Huobi OTC does not charge a transaction fee. For swaps involving other assets, the platform’s fee remains below 1 %. This near‑zero‑fee policy is rare in the industry.
- Security Guarantees
The platform requires that any token listed in an advertisement be genuinely held in a custodial wallet. Assets are released only after both buyer and seller confirm completion of the trade. This design effectively prevents scams, and Huobi, acting as an intermediary, intercepts malicious users to enhance overall transaction safety.
In addition, Huobi OTC operates as a regulated service provider. It has obtained a Distributed Ledger Technology (DLT) licence from the Gibraltar Financial Services Commission (FSC), enabling multi‑currency trading that includes fiat‑to‑crypto, crypto‑to‑fiat, and crypto‑to‑crypto pairs. Supported fiat currencies cover major global units such as the United States Dollar (USD), British Pound (GBP) and Euro (EUR). For fiat deposits and withdrawals, standard banking channels like SWIFT and SEPA are used where applicable. U.S. residents should use Binance.US rather than the global Binance platform for any related fiat‑on‑ramp services.
What Is Huobi OTC?
Huobi OTC is the over‑the‑counter gateway launched by Huobi Group for institutional investors, high‑net‑worth individuals, and anyone needing to execute large‑scale trades. Users post buy or sell advertisements on the platform; the corresponding assets are locked in a custodial wallet. After the counter‑party confirms payment, the platform releases the assets to the buyer, completing a “pay‑first, release‑later” settlement that safeguards both sides. Huobi provides 24/7 customer support to answer any questions that arise during the trading process.

Step‑by‑Step Guide to Using Huobi OTC
The following example walks through the complete process of selling USDT on the Huobi website.
- Visit the Huobi website at https://www.bitaigen.com/binance and click the Log In button in the upper‑right corner of the homepage.

- After logging in, deposit or transfer the digital assets you intend to sell into your fiat‑trading account wallet. Choose the cryptocurrency you wish to trade (USDT in this example), browse the market listings, and select an advertisement that matches your preferred price and payment method. Then click Sell USDT.

- Enter the amount of USDT you want to sell or the corresponding fiat value, verify the quoted price, input your transaction (funds) password, and click Confirm.

- Once the system generates the order, you will wait for the buyer to complete the payment.

- After the buyer clicks I Have Paid, verify that the funds have arrived in your designated bank account (via SWIFT, SEPA, or other supported channels). When you are certain the payment is confirmed, click Confirm Receipt and Release.

- Re‑enter your funds password, tick the box indicating you agree to the terms, and press Confirm Release.

- The locked USDT is then transferred to the buyer’s wallet, and the transaction is completed.

Summary
Huobi OTC delivers a convenient and secure solution for digital‑asset trading of any size through its unified account architecture, low‑cost fee model, and rigorous custodial mechanism. Whether you are an individual looking to liquidate holdings quickly or an institution allocating large sums of capital, the Huobi platform enables efficient over‑the‑counter transactions.
