According to TechFlow, AI Auntie’s monitoring, the suspected Binance address 0xE69...e3Abb has initiated a withdrawal application for 190,000 ETH (worth about $513 million) on Arbitrum in the past week. Perhaps this is to deal with the situation of "a large amount of Arb ETH recharged to Binance but the mainnet ETH was requested".
At present, the first 20,000 ETH withdrawn have passed the waiting period and have been recharged back to the Binance hot wallet.
