Bithumb is one of South Korea's biggest exchanges, and like every Korean platform it trades mostly in KRW — so you convert won to USDT before withdrawing. The send itself is simple once you clear the Korean-specific gate: Bithumb's travel-rule address verification, which registers your destination wallet before funds can leave. Do that once, pick the TRON network, and your USDT lands on Fish & Chips in a couple of minutes for a flat 1 USDT fee — we never charge anything on deposits.
TL;DR: Bithumb → buy/convert to USDT → Withdraw → USDT → TRON (TRC-20) (not ERC20, not BEP20) → register and verify your TronLink address (starts with
T) → arrives in ~2 minutes → connect at fishnchips.io/wallet.
Step 1 — Install TronLink and copy your address
On mobile, install TronLink from the App Store or Play Store. Create or restore a wallet and write the 12-word recovery phrase down offline. If you lose it, the funds are gone — Bithumb support cannot recover a self-custodial wallet.
Your address starts with a capital T and is 34 characters long. Tap it in TronLink to copy.
Step 2 — Withdraw from Bithumb
- Sign in to Bithumb. If you hold KRW, buy or convert to USDT first.
- Go to Withdraw and select USDT.
- Network: choose TRON (TRC-20). This is the single step that can lose your money.
- Register your TronLink address and complete Bithumb's travel-rule verification for the destination. Confirm with 2FA and the prompt Bithumb sends.
- Enter the amount and submit. Approve the final confirmation.
| Network | Bithumb fee | Arrival time | Works for Fish & Chips? |
|---|---|---|---|
| TRON (TRC-20) | ~1 USDT | ~2 min | ✅ Yes |
| ERC20 (Ethereum) | 3–15 USDT | 1–5 min | ❌ Lost funds |
| BEP20 (BNB Chain) | ~0.5 USDT | ~30s | ❌ Lost funds |
Step 3 — Confirm on Fish & Chips
Open fishnchips.io/wallet, tap Connect Wallet, and approve TronLink. Within about a minute of the Tron block confirming, the deposit posts to your balance at 1 USDT = 1,000 points. Your first-ever deposit also triggers the welcome bonus — a 50% match capped at 5,000 points.
You can verify the transfer on Tronscan: search your address and the latest inbound USDT transfer should read "Success".
Common mistakes to avoid
- Skipping the travel-rule verification. Bithumb will not release USDT to an external wallet until the destination is registered and verified. Do it once and it's remembered.
- Leaving the network on ERC20 or BEP20. Always re-check TRON (TRC-20) before you confirm — the other networks never arrive on Fish & Chips.
- Forgetting to convert KRW first. Bithumb trades in won; buy USDT before you try to withdraw.
- Sending dust amounts. Fund at least 10 USDT so you can comfortably withdraw winnings later (our minimum cash-out is 10 USDT).
- Pasting an exchange address. Use your own TronLink address, never another exchange's deposit address.
Once your first deposit lands, every future one takes about 30 seconds because both TronLink and Bithumb's verified-address list remember the address. New here? Read the TRC-20 vs ERC-20 explainer before you send, or head to the arcade lobby for Fish Hunter and Dragon King.
Frequently asked questions
How do I pick the TRC-20 network on Bithumb?
On Bithumb, go to Withdraw, select USDT, then choose the network. Pick 'TRON (TRC-20)' rather than Ethereum (ERC-20) or BNB Chain. TRC-20 is the same Tron rail Fish & Chips accepts and the cheapest option Bithumb offers for USDT.
Why does Bithumb make me verify the destination address first?
Bithumb is a Korean exchange and follows the travel rule, so before sending to an external wallet it asks you to register and verify the destination address. Self-custodial wallets like TronLink are supported — clear the verification once, then reuse the address on every future deposit.
What is Bithumb's withdrawal fee for USDT TRC-20?
Around 1 USDT, flat, on the TRON (TRC-20) network. The fee is the same whether you send 20 USDT or 2,000 USDT, which makes Tron the cheapest way out of Bithumb — far below the Ethereum (ERC-20) fee.
What is Bithumb's minimum USDT TRC-20 withdrawal?
Bithumb's USDT withdrawal minimum is small (a few USDT), but to actually withdraw winnings later you need at least 10 USDT on Fish & Chips (our minimum cash-out), so funding 10 USDT or more from the start is the cleanest path.
