Stablecoins like USDT (Tether) have become essential tools for crypto traders and investors worldwide, offering stability in an otherwise volatile market. Whether you're in South Korea or using global platforms like Huobi, understanding how to deposit, buy, and manage USDT is crucial for seamless digital asset transactions.

This guide walks you through everything you need to know about acquiring USDT — from fiat on-ramps to blockchain-level technical requirements — while focusing on practical steps, safety tips, and platform-specific workflows.

Understanding USDT: The Basics

USDT, or Tether, is a stablecoin pegged 1:1 to the US dollar, issued by Tether Limited. It operates across multiple blockchains such as ERC-20 (Ethereum), TRC-20 (Tron), BEP-20 (Binance Smart Chain), and others. Its primary purpose is to maintain price stability while enabling fast and low-cost transfers globally.

Can You Buy USDT with a Credit Card?

No, you cannot directly purchase USDT using a credit card on most major platforms. While some third-party services may allow it, mainstream exchanges often restrict this due to chargeback risks and regulatory concerns.

However, you can use your credit card to fund a bank account or digital wallet that supports fiat-to-crypto purchases. From there, you can exchange fiat money (like USD or KRW) for USDT via peer-to-peer (P2P) trading or instant buy features.

💡 Tip: Always verify the legitimacy of any service claiming to accept credit cards for crypto purchases to avoid scams.

How to Deposit USDT on Huobi (Now HTX)

Huobi, now rebranded as HTX, allows users to deposit and trade USDT easily through both crypto transfers and fiat on-ramps.

Step-by-Step: Deposit USDT into Your Huobi Account

  1. Log in to your Huobi account
  2. Go to Assets > Deposit
  3. Search for USDT and select it
  4. Choose the correct network (e.g., ERC-20, TRC-20, etc.)
  5. Copy the generated deposit address or scan the QR code
  6. Transfer USDT from your external wallet or exchange using the same network
⚠️ Important: Ensure the sending network matches the receiving network. Sending TRC-20 USDT to an ERC-20 address will result in permanent loss.

Huobi does not charge fees for USDT deposits or withdrawals, but always confirm current policies on their official site.

If you're looking to acquire USDT using Korean won (KRW), proceed with P2P trading — which is supported on Huobi.

How to Use ERC-20 USDT: Gas Fees Explained

When dealing with ERC-20 USDT, remember that all transactions occur on the Ethereum network — which means you'll need ETH for gas fees.

Key Points:

What Happens If You Don’t Have ETH?

You won’t be able to transfer your USDT even if your balance is high. This is a common mistake among beginners.

Solution:

Before transferring ERC-20 USDT:

  1. Deposit a small amount of ETH (e.g., 0.01 ETH) into the same wallet
  2. Use it to cover gas costs when moving USDT
🔄 Alternative: Use TRC-20 USDT instead — it runs on the Tron network with nearly zero fees and no need for additional tokens.

How to Deposit USDT to Overseas Exchanges

To trade or store USDT on international platforms (like OKX, Bybit, or Kraken):

  1. Log in to your target exchange
  2. Go to Deposit > Cryptocurrency
  3. Select USDT and choose the preferred network (e.g., TRC-20, ERC-20)
  4. Copy the deposit address
  5. Send USDT from your current wallet/exchange using the same network

Always double-check:

Mistakes in these fields can lead to irreversible fund loss.

How to Convert USDT to USD

Need real dollars? Here are two main ways:

1. Through Tether Company (Direct Redemption)

Tether allows institutional users to redeem USDT for USD directly, but:

Not ideal for retail users.
