Binance recorded a net outflow of 23,137 BTC in the seven days through Sept. 27, the exchange's heaviest weekly Bitcoin withdrawal total in more than three years, according to on-chain flow data on CryptoQuant's netflow dashboard.

The reading is the largest weekly net outflow for Binance since June 2023. Exchange netflow measures the difference between cryptocurrency deposits into and withdrawals from exchange-controlled wallets over a given period. A net outflow indicates that more Bitcoin left Binance wallets than entered them during the measured week. Analysts track these figures because coins held in exchange wallets are readily available for trading, while coins moved to external addresses sit outside the venue's direct custody. The on-chain data records wallet movements only and does not identify the parties behind the transfers or their reasons for moving funds.

Binance is the largest of the major cryptocurrency exchanges by trading volume, and its wallets are among the most closely watched addresses in on-chain analytics. Netflow dashboards such as CryptoQuant's track these movements to measure how coins shift between exchange custody and outside wallets. Subsequent weekly readings on the dashboard will show whether withdrawal activity held at a similar pace or eased after the Sept. 27 window closed.

The figure was highlighted in a report published by COINOTAG on Oct. 6, 2026, which cited the CryptoQuant netflow data.
