Bitcoin ETFs lose $643 million in the first session after the Binance hack

The numbers. Farside Investors publishes flows for every US spot bitcoin ETF. On October 30: IBIT minus $233.7 million, FBTC minus $201 million, ARKB minus $129.5 million, GBTC minus $53.3 million, BITB minus $25.7 million. Together that is $643.2 million. Before that came four days of inflows: $110.3 million, $176 million, $137.3 million and $17.2 million.

Why Friday. According to Decrypt, the attack on Binance began on Thursday at 4:05 p.m. New York time, after US markets had closed. So Thursday's $17.2 million inflow came before the theft, and Friday was the first day fund investors could react.

The month. Decrypt puts October's bitcoin ETF outflows at about $516 million. Since launch in January 2024 the funds still have $57.4bn of net inflows and $103.2bn in assets. One bad day is visible, but it is not a collapse of the whole inflow story.

Price and other funds. Bitcoin fell about 4% on Friday to roughly $76,400, with more than $1.3bn of leveraged positions liquidated. By Saturday it had steadied near $77,520. Ethereum ETFs lost $155.7 million on Friday, their fifth day of outflows in a row, about $431 million in total.

Who it touches. Anyone holding bitcoin or shares of bitcoin funds, and anyone who trades crypto on ETF flows. Outflows do not mean the price must fall further, but they show the mood of large buyers.
