Odaily Planet Daily News Lookonchain monitoring shows that two addresses use the price difference of the same token on different chains to earn arbitrage through cross-chain, earning $1,200 to $12,000 a day. The trading strategy is: if someone sells token A on Ethereum, the price of token A will suddenly plummet, and the price of token A on BSC is not affected. Therefore, arbitrageurs can buy token A at a low price on Ethereum, then cross-chain to BSC and sell it. Among them, an arbitrageur spent 370 USDC to buy NGL on Ethereum, then cross-chained it to BSC and sold it at 382 DAI. After deducting gas fees, the profit is about $7. However, not all arbitrage can be profitable. Another arbitrageur spent 2,000 BUSD to buy DCK on BSC, and then cross-chained it to Ethereum and sold it for only 1,998.88 USDT. After deducting gas fees, he will lose about $21. A rough calculation shows that these two addresses arbitrage 5-10 times per hour, making a profit of $50-500 per hour and $1,200-12,000 per day. The more large sales/purchases on the chain, the more money the arbitrageurs make. However, this strategy is difficult to implement through manual trading. Arbitrageurs need Bots to monitor abnormal transactions on the chain and quickly buy, cross-chain, and sell.
