Recently, a friend asked me about arbitrage trading with moving bricks, so I organized some of my practical experience.

The logic of moving brick arbitrage is actually very simple—profit from the price difference of USDT across different exchanges. For example, buy USDT at a low price on Platform A, quickly transfer it to Platform B, and sell at a higher price. The difference between the two prices is the profit. It sounds easy, but in practice, it requires precise execution.

The core profit formula is: single-trade profit equals principal multiplied by the price difference rate minus fees. For example, with a 100k USDT principal and a 0.3% price difference, you can earn about 300 USDT per trade. If you seize 3 opportunities a day, the daily average profit can approach 900 USDT. Of course, this assumes the price difference is stable enough and that fees don’t eat into the profit.

Executing this involves several key steps. First is monitoring the price difference. I use TradingView combined with my own Python monitoring script. The main focus is on real-time USDT/USD prices from major exchanges. When the spread exceeds 0.2%, an alert is triggered because below that threshold, fees typically outweigh the profit. Next is capital preparation: it’s recommended to open both ERC20 (low fee for large transfers) and TRC20 (small amount fast transfers) channels. The principal should ideally be over 10k USDT, because moving less than 5,000 USDT per trade isn’t very cost-effective.

The arbitrage execution process is basically three steps: buy USDT at a low price on Exchange A, instantly transfer it to Exchange B, then sell at a higher price on Exchange B, locking in the profit immediately. If you trade frequently, consider using an API-based arbitrage bot with a set price difference threshold for automatic execution—this greatly improves efficiency.

There are some efficiency tips worth noting. Prioritize stablecoin pairs, such as USDT against BUSD, to avoid volatility interference. Focus on trading during volatile periods, like during Federal Reserve announcements or when certain platforms experience outages, as spreads tend to widen then, creating the best arbitrage opportunities.

But risk control is crucial. Transaction fees are the most direct threat, so the spread must exceed 0.3% to be worthwhile. I’ve seen people operate with spreads as low as 0.1%, ending up with a loss of about 0.05%. Withdrawal delays are another pitfall—only choose channels that settle within 30 minutes. Someone once used TRC20 during network congestion and got stuck for 6 hours; by the time the withdrawal succeeded, the spread had disappeared. Also, be aware of black swan events: if daily profits exceed 500 USDT, I recommend withdrawing 50% immediately, because exchanges have temporarily suspended withdrawals before, and having your principal frozen is a big loss.

How to calculate costs and profits? Using 10k USDT as an example, the round-trip fee is about 0.1% plus around $1 withdrawal fee. If you have VIP status on the exchange, fees can drop to 0.08%. Slippage with market orders is roughly 0.05%, which can be reduced by using limit orders with price offset protections. The average daily arbitrage opportunities are about 2 to 3 times (when spreads exceed 0.3%). Monitoring multiple platforms improves results. Over 30 trades, the monthly net profit is roughly 9,000 USDT, but you should reserve about 10% for unexpected losses.

If you want to start arbitrage trading seriously, I suggest completing the preparatory steps first. Open accounts on several major exchanges, complete Level 3 KYC verification, and set up dual-channel wallets. Then, run a small test with 1,000 USDT to go through the entire process—record actual spreads, fees, and settlement times—to better understand the rhythm of operations. Once verified, execute with the principal divided into three rolling batches to avoid full exposure. Make sure to withdraw profits to a cold wallet before 10 PM daily—this is an important habit for protecting your funds.

Finally, a reminder: past returns do not guarantee future performance. According to data from 2024, arbitrage opportunities have decreased by about 40%, meaning you need to upgrade your monitoring scripts’ accuracy to keep pace with market changes. While moving brick arbitrage seems stable, the market is evolving, and strategies must adapt. If you’re interested in this type of trading, you can follow USDT real-time prices on Gate, compare spreads at different times, and gradually accumulate experience.
