Cryptocurrency markets have evolved rapidly, bringing with them a surge of digital assets. Among these, USDT (Tether) stands out as one of the most widely used stablecoins—pegged to the U.S. dollar at a 1:1 ratio. This stability makes USDT a preferred tool for traders seeking low-risk profit opportunities through arbitrage, commonly known as "USDT搬砖" or USDT brick-moving.
But just how profitable is USDT arbitrage? And what steps should a beginner take to get started? This comprehensive guide explores the mechanics, potential profits, risks, and best practices for executing USDT arbitrage successfully.
What Is USDT Arbitrage?
USDT arbitrage involves buying USDT on one cryptocurrency exchange where the price is lower and selling it on another where the price is higher. Because USDT is designed to maintain a stable value of $1, even small deviations across exchanges create opportunities for risk-averse traders to capture profits.
This strategy relies on market inefficiencies—temporary price discrepancies caused by differences in liquidity, demand, or local regulations across platforms.

How Profitable Is USDT Arbitrage?
The profit from USDT arbitrage varies depending on several factors:
- Price spread between exchanges
- Transaction and withdrawal fees
- Network congestion and confirmation times
- Account verification levels
- Regional payment methods and liquidity
Typically, price differences range from 0.3% to 2%, though during periods of high market volatility or regulatory shifts, spreads can exceed 3%. For example:
If you buy 10,000 USDT at $0.985 per unit on Exchange A and sell it at $1.01 on Exchange B, your gross profit would be $250 before fees.
After accounting for transaction costs (withdrawal, network, and trading fees), net profit usually lands between 1% and 1.8% per cycle. While this may seem modest, consistent execution across multiple cycles can yield substantial returns over time.
Step-by-Step USDT Arbitrage Tutorial
Follow this structured process to execute your first USDT arbitrage trade safely and efficiently.
Step 1: Register on Two Major Exchanges
Choose two reputable exchanges with strong liquidity and C2C (peer-to-peer) trading options. Popular choices include Binance and OKX.
Ensure both accounts are fully verified to avoid withdrawal limits or delays.
👉 Start trading with fast withdrawals and low fees on a trusted global platform.
Step 2: Buy USDT at a Discount via C2C
- Log in to Exchange A.
- Navigate to Trade > C2C Trading.
- Select Buy USDT.
- Filter by your preferred payment method (e.g., bank transfer, Alipay).
- Choose an offer priced below $1 (e.g., 6.8 RMB when USD is ~7.2 RMB).
- Complete the purchase using your local currency.
Pro Tip: Prioritize sellers with high completion rates and positive feedback.
Step 3: Withdraw USDT Using TRC-20 Network
- Go to Wallet > Spot Account > Withdraw.
- Select USDT as the token.
- Choose TRC-20 as the network (low fee, fast confirmation).
- Paste the deposit address from Exchange B.
- Confirm withdrawal after double-checking all details.
⚠️ Never send funds using a mismatched network (e.g., ERC-20 to a TRC-20 address). This may result in permanent loss.
Step 4: Deposit USDT on the Second Exchange
- Log in to Exchange B (e.g., OKX).
- Go to Assets > Deposit.
- Select USDT and ensure TRC-20 is selected.
- Copy the generated deposit address.
- Use this address when withdrawing from Exchange A.
Deposits typically arrive within 1–5 minutes.
Step 5: Sell USDT at a Premium
- Navigate to Buy Crypto > C2C.
- Click Sell USDT.
- Select a buyer offering above $1 (e.g., 7.3 RMB per USDT).
- Confirm the sale and receive fiat in your local bank account.
The difference between your buy and sell prices—minus fees—is your arbitrage profit.
Is USDT Arbitrage Legal?
Yes, USDT arbitrage itself is not illegal in most jurisdictions. However, compliance with local laws is critical:
- Anti-Money Laundering (AML) Regulations: Large or frequent transactions may trigger scrutiny.
- KYC Requirements: Most platforms require identity verification for significant volumes.
- Tax Reporting: Profits may be subject to capital gains or income tax depending on your country.
- Exchange Policies: Some platforms restrict automated trading or high-frequency arbitrage.
Always operate within the terms of service of each exchange and consult a financial advisor if unsure about tax obligations.

Use TRC-20 for lowest fees (~$1) and fast confirmations. Avoid ERC-20 unless necessary due to higher gas costs.

Not necessarily. You can begin with as little as $500–$1,000. However, higher capital improves profitability per cycle and helps absorb fixed fees.
