Moving crypto from Upbit to Binance is one of the most common tasks Korean crypto users face. Upbit is where most Koreans buy crypto with Korean Won. Binance is where they access global markets, futures trading, passive income products, and hundreds of coins that are not listed on Korean exchanges. The bridge between the two is a crypto transfer, and doing it wrong costs real money.
This guide explains exactly which assets to use, which networks to choose, how much each option costs, and what mistakes to avoid so that you keep as much of your money as possible during the transfer.
Why the Asset and Network You Choose Determine Your Transfer Cost
Not all crypto transfers cost the same. The fee you pay depends on two things: the asset you send and the blockchain network it travels on. Choosing the wrong combination can cost you ten to fifteen times more than necessary.
Every blockchain charges a fee to process transactions. This fee is not set by Upbit or Binance. It is determined by the network itself and fluctuates based on how busy the network is at that moment. Upbit passes this network fee directly to the user when you withdraw. Binance does not charge a fee to receive a deposit, so the only cost you pay is the Upbit withdrawal fee.
The Ethereum network is the most expensive option for most assets. When the network is congested, withdrawing USDT via ERC20 from Upbit can cost anywhere from 5 to 20 USDT in fees. On a transfer of 100 USDT, that is a 5% to 20% loss before the money even arrives in Binance.
The Tron network (TRC20) is the most cost-effective option for USDT transfers. The withdrawal fee from Upbit for TRC20 USDT is fixed at 1 USDT regardless of the transfer amount. Whether you send 100 USDT or 10,000 USDT, the fee is the same 1 USDT. This makes TRC20 the clear choice for USDT transfers of any size.
XRP is the best option when you want the fastest possible transfer. XRP transactions on the Ripple network confirm in 3 to 5 seconds and the withdrawal fee from Upbit is 1 XRP, which is worth less than 1 USD at most price points. The transfer typically arrives in Binance within 30 seconds to 2 minutes.
The BNB Chain (BEP20) is another low-cost option for USDT and other supported assets. The withdrawal fee for USDT via BEP20 is approximately 0.29 USDT, which is even cheaper than TRC20. However, not all Korean exchanges support BEP20 withdrawals, so check whether Upbit offers this network for the asset you want to send before relying on it.
The Cheapest and Fastest Transfer Methods Side by Side
Understanding the options in concrete terms makes the decision straightforward. Here is how the main transfer methods compare based on real costs as of 2026.
For USDT transfers, TRC20 costs 1 USDT per transfer regardless of amount. ERC20 costs between 5 and 20 USDT, depending on Ethereum network congestion. BEP20 costs approximately 0.29 USDT where available. TRC20 is the recommended default for most users because it is universally supported, reliably cheap, and fast enough for most purposes.
For XRP transfers, the fee is 1 XRP per transfer. At a price of around 0.50 USD per XRP, the cost is approximately 0.50 USD. Confirmation takes under 2 minutes. XRP is the best choice when you need funds in Binance quickly and are comfortable converting XRP to USDT or another asset after arrival.
For Bitcoin transfers, the fee from Upbit ranges from 0.0005 BTC to 0.001 BTC, depending on network conditions. At a Bitcoin price of 90,000,000 KRW, that fee equals 45,000 to 90,000 KRW per transfer. Bitcoin transfers are not recommended for routine funding because the fee is high relative to the transfer amount unless you are moving a very large sum where the fixed fee becomes a small percentage.
For Ethereum transfers, the fee from Upbit is approximately 0.003 ETH. At an ETH price of 4,000,000 KRW, that equals around 12,000 KRW per transfer. This is more reasonable than Bitcoin for mid-size transfers, but TRC20 USDT remains cheaper for most use cases.
A real example makes this clear. Suppose a user wants to move 500,000 KRW worth of value from Upbit to Binance. They have three options.
Option one: buy USDT on Upbit and withdraw via TRC20. Fee is 1 USDT, approximately 1,350 KRW. Total cost of transfer: 1,350 KRW.
Option two: buy USDT on Upbit and withdraw via ERC20. Fee is 8 USDT on a moderately busy day, approximately 10,800 KRW. Total cost of transfer: 10,800 KRW.
Option three: buy XRP on Upbit and withdraw via Ripple. Fee is 1 XRP, approximately 680 KRW. Total cost of transfer: 680 KRW.
The difference between the cheapest option and the most expensive option on the same 500,000 KRW transfer is over 10,000 KRW. On a monthly basis for an active user, that difference compounds into a meaningful amount.

Step-by-Step: How to Transfer USDT from Upbit to Binance via TRC20
This is the most commonly used transfer method among Korean Binance users. Follow these steps in order.
Step 1: Get your Binance TRC20 deposit address.
Open the Binance app and tap the wallet icon at the bottom of the screen. Tap “Deposit.” In the search bar, type USDT and select it. Binance shows a list of supported networks. Tap TRC20. The app displays your USDT TRC20 deposit address as a QR code and a text string. Tap the copy button to copy the address to your clipboard. Do not close this screen yet.
Step 2: Verify the address format.
A TRC20 USDT address always starts with the letter T and is 34 characters long. For example: TQn9Y2khEsLJW1ChVWFMSMeRDow5KcbLSE. If the address you copied does not start with T, you have selected the wrong network. Go back and select TRC20 again.
Step 3: Go to Upbit and initiate the withdrawal.
Log in to Upbit and go to your USDT wallet. Tap “Withdraw.” Select TRC20 as the network. Paste the Binance address into the withdrawal address field. Double-check that the first and last four characters of the pasted address match what is displayed in Binance. Enter the amount you want to send. Upbit shows the withdrawal fee (1 USDT) and the amount that will arrive in Binance after the fee is deducted. Complete any two-factor authentication required by Upbit and submit the withdrawal.
Step 4: Wait for the deposit to arrive.
Return to Binance and check your wallet. TRC20 USDT transfers typically arrive within 1 to 5 minutes. Binance sends a push notification when the deposit is credited. You can also check the deposit status in the “Transaction History” section of your Binance wallet.
A real example: a user in Busan transfers 1,000 USDT from Upbit to Binance via TRC20 on a Tuesday afternoon. The withdrawal is submitted at 14:32. The deposit is credited in Binance at 14:35. Total time: 3 minutes. Total fee paid: 1 USDT. The user now has 999 USDT in their Binance spot wallet ready to use.
The Network Matching Rule: The Most Important Thing to Understand
The single most important rule in any crypto transfer is that the network used to send must match the network used to receive. This rule applies to every asset and every exchange, not just Upbit and Binance.
If you withdraw USDT from Upbit using the TRC20 network and your Binance deposit address is set to ERC20, the funds are sent to an incompatible address. In most cases, this results in permanent loss of the transferred amount. Neither Upbit nor Binance can reverse a completed blockchain transaction.
This is not a theoretical risk. It happens regularly to users who copy a deposit address without checking the network. A user who copies their Binance ERC20 USDT address and then selects TRC20 on Upbit sends funds to a valid-looking but incompatible address. The transaction confirms on the blockchain, but the funds never appear in Binance because the address belongs to a different network.
The rule to follow is simple. Before confirming any withdrawal, check the network shown in Upbit and the network shown in Binance. Both must show the same network name. TRC20 to TRC20. ERC20 to ERC20. BEP20 to BEP20. If they do not match, stop and correct the address before proceeding.
Always Test with a Small Amount First
No matter how many times you have done a transfer before, sending a small test amount to a new address is a habit worth keeping. The cost of a test transfer is 1 USDT. The cost of sending 5,000 USDT to a wrong address is 5,000 USDT.
The process is simple. Send 10 USDT first. Wait for it to arrive in Binance. Confirm the amount is correct and the address is working. Then send the remaining amount.
A real example: a user is setting up Binance for the first time and wants to transfer 2,000,000 KRW worth of USDT. They send 10 USDT as a test. It arrives in 4 minutes. They then send the remaining 1,470 USDT. Total extra time spent on the test: 5 minutes. Total extra fee for the test: 1 USDT. The user now has confidence that the address is correct and the transfer works as expected.
Experienced users who have transferred to the same Binance address many times can skip the test. But any time you use a new address, whether it is a new Binance account, a different wallet, or a different asset, run the test first.
What to Do If Your Transfer Does Not Arrive
Most TRC20 USDT transfers arrive within 5 minutes. If your transfer has not arrived after 30 minutes, check the following before contacting support.
First, confirm the transaction was submitted successfully on Upbit. Go to your Upbit withdrawal history and verify the status shows “Completed” rather than “Pending” or “Processing.” If it shows pending, the transfer has not left Upbit yet and you need to wait.
Second, check the blockchain directly. Copy the transaction ID (TXID) from your Upbit withdrawal history and paste it into Tronscan (tronscan.org) for TRC20 transactions. Tronscan shows the real-time status of the transaction on the Tron blockchain. If the transaction shows as confirmed on Tronscan but has not appeared in Binance, the deposit may be pending Binance’s internal crediting process, which can take up to 30 minutes during high-traffic periods.
Third, check that you deposited to the correct network address in Binance. If Tronscan shows the transaction went to an address that does not match your Binance TRC20 address, the funds were sent to the wrong address and you will need to contact Binance support with the TXID to investigate recovery options.
Binance support can sometimes recover funds sent to the wrong network address within the same exchange, but this process is not guaranteed, takes several days, and may involve a recovery fee. Prevention through address verification is always the better approach.
Transferring crypto from Upbit to Binance is a routine process that becomes second nature after the first few times. The key decisions are choosing TRC20 USDT or XRP for cost efficiency, verifying network matching on both sides, and testing with a small amount before large transfers. These three habits eliminate the most common and costly mistakes and make every transfer straightforward.
