In recent years, the demand for stablecoins has surged—especially among investors seeking stability in the volatile crypto market. USDT (Tether) stands out as one of the most widely used digital assets, particularly in Hong Kong, where more people are turning to cryptocurrency for trading and value preservation. This guide will walk you through everything you need to know about USDT, from its fundamentals to safe and efficient ways to buy it locally.
What Is USDT Tether?
USDT, also known as Tether, is a type of stablecoin—a cryptocurrency pegged to a traditional fiat currency. Specifically, each USDT is designed to maintain a 1:1 value with the U.S. dollar. Issued by Tether Limited, the coin aims to combine the flexibility of digital currencies with the stability of fiat money.
Unlike highly volatile assets like Bitcoin or Ethereum, USDT's price remains relatively steady. This makes it ideal not for speculation, but for transactions, trading, and storing value within the crypto ecosystem.
The company claims that every USDT in circulation is backed by equivalent reserves in U.S. dollars held in designated bank accounts. While debates around full transparency continue, USDT remains one of the most trusted and widely adopted stablecoins globally.

Common Uses of USDT
1. Transaction Medium
USDT acts as a bridge between fiat currencies and other cryptocurrencies. On most major exchanges, you can quickly swap Bitcoin (BTC), Ethereum (ETH), or local currency into USDT—making it easier to enter and exit trades without relying on traditional banking systems.
Because its value is stable, traders often use USDT as a neutral holding asset during market uncertainty.
2. Value Preservation
Crypto markets are notoriously volatile. When prices drop sharply, investors frequently convert their holdings into USDT to protect gains and avoid further losses. Since USDT maintains a stable value, it offers a reliable way to hedge against market swings while staying within the digital asset space.
Understanding ERC-20 vs TRC-20 Networks
When buying or transferring USDT, you’ll often see options labeled ERC-20 and TRC-20. These refer to different blockchain networks on which USDT operates—and choosing the right one impacts speed, cost, and compatibility.
ERC-20 (Ethereum Network)
This version of USDT runs on the Ethereum blockchain using the ERC-20 token standard.
Key Features:
- High Security: Ethereum’s decentralized and well-established network provides strong security.
- Wide Compatibility: Supported by most wallets (e.g., MetaMask, Trust Wallet) and decentralized applications (dApps).
- Higher Fees: Due to network congestion, gas fees can be significantly higher—sometimes exceeding several dollars per transaction.
Ideal for users who prioritize security and compatibility over cost.
TRC-20 (Tron Network)
TRC-20 USDT operates on the Tron blockchain, offering faster and cheaper transactions.
Key Features:
- Fast Transactions: Transfers are typically confirmed in seconds.
- Low Fees: Transaction costs are nearly negligible—often less than $0.1.
- Limited Wallet Support: Not all wallets support TRC-20, so ensure your wallet is compatible before sending funds.
Best suited for frequent traders or those making smaller transfers where cost efficiency matters.
⚠️ Important: Never send ERC-20 USDT to a TRC-20 address, or vice versa. Doing so may result in permanent loss of funds. Always double-check the network type with your recipient.
Is USDT a Scam?
No—USDT itself is not a scam. It’s a legitimate digital asset backed by reserves and used across thousands of platforms worldwide. However, because of its popularity, fraudsters often exploit it in scams targeting inexperienced users.
Common schemes include:
- Fake OTC (over-the-counter) trading platforms offering “discounted” USDT.
- Phishing sites mimicking real exchanges.
- Social engineering tactics promising guaranteed returns.
Recent reports highlight cases such as:
- A woman in Tai Kok Tsui losing HK$90,000 after selling USDT through an unverified platform.
- A South Korean man paying HK$700,000 but never receiving his coins, leading to police involvement.
These incidents underscore the importance of using trusted, regulated channels when buying or selling USDT.

How to Buy USDT in Hong Kong
There are two primary methods to purchase USDT in Hong Kong:
- Cryptocurrency Exchanges
- Over-the-Counter (OTC) Trading Platforms
Let’s explore both options in detail.
Option 1: Buying USDT via Cryptocurrency Exchanges
Popular platforms like Binance and HashKey allow Hong Kong residents to buy USDT directly using HKD or other payment methods.
Step-by-Step Process:
- Choose a Reputable Exchange
Select a licensed exchange with strong security measures and user protection policies. - Create an Account & Complete KYC
Register and complete Know Your Customer (KYC) verification with your ID or passport. - Deposit Funds
Add money via bank transfer, credit card, or supported e-wallets like AlipayHK. - Buy USDT
Navigate to the trading pair (e.g., HKD/USDT), enter the amount, and confirm the purchase. - Withdraw to Your Wallet (Optional)
For enhanced security, transfer your USDT to a private digital wallet instead of leaving it on the exchange.
While convenient, exchanges may charge higher fees and have withdrawal limits—especially for new users.
Option 2: OTC (Over-the-Counter) Trading
OTC platforms facilitate direct peer-to-peer or broker-mediated trades, ideal for large-volume transactions without affecting market prices.
Why Choose OTC?
- Faster settlement
- Better exchange rates
- Support for high-value trades
- Face-to-face or bank transfer options
For Hong Kong users, selecting a local OTC provider with physical offices adds an extra layer of trust and accountability.

Q1: Can I buy USDT with cash in Hong Kong?
Yes. Several OTC providers allow cash transactions at physical locations. Always verify the legitimacy of the service and conduct trades in secure environments.

Use TRC-20 for lower fees and faster transfers if your wallet supports it. Choose ERC-20 for broader compatibility, especially when interacting with DeFi platforms or dApps.

While exchanges offer convenience, they are vulnerable to hacking. For long-term storage, consider transferring your USDT to a cold wallet (hardware wallet) for maximum security.

Yes. Most exchanges and OTC platforms allow you to sell USDT for Hong Kong dollars via bank transfer or other payout methods.
Q6: What should I do if I send USDT to the wrong network?
Immediately contact the receiving wallet provider or exchange support team. Recovery is not guaranteed, especially if sent across incompatible networks (e.g., ERC-20 to TRC-20). Prevention through careful verification is crucial.
