Binance CEO Changpeng Zhao tweeted last night that the net outflow of Binance platform assets in the past 24 hours was about 392 million US dollars. Binance platform wallet addresses are public. Some third-party analysis counts USD-marked AUM changes as outflows, but this also includes outflows due to lower cryptocurrency prices (decreases in AUM). They are two different concepts. Some even only measure outflows, not inflows. In days of wild price swings like today, many arbitrage traders move large amounts of money between trading platforms, often much larger than usual. For reference, Binance processed a net outflow of $7 billion in a single day in November last year.
