Upbit and Bithumb USDT Withdrawals: TRC-20 Fee Guide for Korean Users
You bought USDT on Upbit or Bithumb and now you need to move it. Maybe you are sending it to a friend. Maybe you are moving it to a personal wallet for safekeeping. Maybe you are transferring it overseas. The withdrawal screen shows multiple network options and different fees for each. Choosing the wrong one can cost you 5x more than necessary. Choosing the right one is the first step. But there is a second fee most Korean users do not know about: the Tron network fee that hits every time you send USDT from your personal wallet after withdrawal. This guide covers both fees, the exchange withdrawal and the network transfer, because saving money on the first one while ignoring the second is like negotiating a discount on a car and then filling it with premium fuel every week.
Which Network to Choose
When you withdraw USDT from any Korean exchange, you must select which blockchain network to use. The USDT is the same regardless of network, but the fee, speed, and destination wallet compatibility are different.
| Network | Typical Fee | Speed | Best For |
|---|---|---|---|
| TRC-20 (Tron) | ~1 USDT | 3 seconds | Personal wallets, P2P, overseas transfers |
| ERC-20 (Ethereum) | 3-10 USDT | 1-5 minutes | DeFi protocols on Ethereum |
| BEP-20 (BSC) | ~0.3 USDT | 3-5 seconds | BSC ecosystem only |
| Arbitrum/Optimism | ~0.1-0.5 USDT | ~15 seconds | Ethereum L2 DeFi |
For most Korean users sending USDT to another person, to a personal wallet, or overseas: TRC-20 is the right choice. It has the widest support globally. Nearly every wallet, exchange, and P2P platform accepts TRC-20 USDT. If you are unsure what the recipient supports, TRC-20 is the safest default.
Critical rule: the receiving wallet must support the same network you chose. Sending TRC-20 USDT to an ERC-20 address (or vice versa) results in permanent loss of funds. TRC-20 addresses start with "T" and are 34 characters. Double-check before confirming.
Upbit vs Bithumb Withdrawal Fees
Both Upbit and Bithumb charge a flat withdrawal fee for USDT. This fee goes to the exchange, not to the network. It covers the exchange's cost of processing the withdrawal and broadcasting it to the blockchain.
As of early 2026, TRC-20 USDT withdrawal fees on both exchanges are approximately 1 USDT. This can change, so always check the current fee on the withdrawal confirmation screen. ERC-20 fees are significantly higher on both platforms, typically 3-10 USDT depending on Ethereum gas prices at the time.
Upbit and Bithumb together handle over 80% of Korean domestic crypto volume. Both are regulated under the existing Virtual Asset User Protection Act. Both require full KYC. Both support KRW deposits via Korean bank transfer.
For USDT specifically, there is no meaningful difference between them. Choose whichever exchange you already have an account on. The withdrawal fee difference between the two is negligible on TRC-20.
The Second Fee: After Withdrawal
Here is what most Korean guides do not explain. The exchange withdrawal fee is only the first cost. Once USDT is in your personal wallet (TronLink, Trust Wallet, Ledger, or any TRC-20 compatible wallet), every subsequent transfer costs a separate Tron network fee.
This network fee is paid in TRX, not USDT. Without Energy in your wallet, the fee is approximately 6.4 TRX (about 2,500 KRW) per transfer. If the recipient has never received USDT before (a new wallet), it doubles to approximately 13.4 TRX (about 5,200 KRW).
This means a typical flow for a Korean user looks like this: buy USDT on Upbit (KRW), withdraw to personal wallet (1 USDT fee), send to recipient (6.4 TRX fee). The total cost is roughly 1 USDT + 6.4 TRX = approximately 4,000 KRW. For a single transfer this is acceptable. For someone who sends USDT regularly, these TRX fees accumulate into a significant annual cost.
How to Cut the Second Fee in Half
The Tron network charges 6.4 TRX because your wallet has no Energy loaded. Energy is a computational resource that, when present, covers the processing cost of the transfer without burning TRX.
By renting Energy before sending, you pay approximately 3-4 TRX total (the rental cost) instead of 6.4 TRX (the burn cost). The saving is roughly 3 TRX per transfer, or about 1,200 KRW.
For a user doing 5 transfers per week, that is 15 TRX saved per week, 780 TRX per year, roughly 305,000 KRW. Not a trivial amount when compounded over time.
