US spot Bitcoin ETFs recorded $643.33 million in net outflows on Friday, ending four consecutive sessions of inflows and leaving the week in negative territory. The withdrawals landed on the first full trading day after Binance disclosed a breach affecting roughly $6.3 billion in cryptocurrency.

Bitcoin traded near $77,600 on Saturday, according to market data, after falling below $77,000 at the height of Friday's selloff. Ether and Solana funds also posted net withdrawals, extending a broader retreat across crypto investment products.

Because the breach occurred after Thursday's close of US equity markets, Friday was the first complete session in which ETF investors could respond. The flow figures capture the scale of redemptions, but not the reasons behind each investor's decision. Spot Bitcoin ETFs debuted in the United States in January 2024 and have since become a primary channel through which institutional and retail investors gain exposure to the asset.

Bitcoin ETF Outflows Erase Four Days of Inflows

Friday's outflows reversed the $440.73 million in net inflows recorded from Monday through Thursday, leaving the five-day period roughly $202.6 million in the red, according to SoSoValue figures.

BlackRock's iShares Bitcoin Trust (IBIT) led the withdrawals with $233.70 million in outflows. Fidelity's FBTC followed at $201.04 million, and ARK 21Shares' ARKB recorded $129.55 million in net withdrawals. Grayscale's GBTC and Bitwise's BITB lost $53.32 million and $25.72 million, respectively.

The day's outflows spread across five major funds, a contrast to earlier in the week when inflows were concentrated in IBIT. A net outflow means that redemptions of fund shares exceeded new creations during the session, a measure of how much capital left the products that day.

Trading activity also surged. Trading value across Bitcoin funds reached $6.35 billion on Friday, up from $2.11 billion the previous day. Total net assets stood at $98.14 billion at the end of the session, slipping below the $100 billion mark. The decline reflects both net fund outflows and the drop in the market value of the Bitcoin the funds hold.

ETF shares give investors exposure to Bitcoin's price through a standard brokerage account without requiring direct custody of the asset. Their daily flows can help track demand for the products, though they do not reveal individual motives. Friday's withdrawals coincided with broader market stress, including declines in US technology stocks, and the figures alone cannot establish how much of the outflow resulted from the exchange breach. The next sessions' daily flow reports will show whether Friday's reversal marked a one-session reaction or a more sustained change in demand.

Crypto Markets Face Fresh Tests After the Binance Breach

The retreat extended well beyond Bitcoin products. US spot Ether ETFs lost $155.85 million on Friday, their fifth consecutive session of net outflows, with BlackRock's ETHA accounting for $76.64 million of that amount. Ether fund withdrawals for the full week reached approximately $431.5 million.

Solana ETFs recorded $10.74 million in outflows on Friday, taking their weekly withdrawals to about $71.5 million. XRP products also posted a smaller net outflow.

The hack added a security shock to a market already facing volatility. Binance, the world's largest cryptocurrency exchange by trading volume, said the breach affected roughly $6.3 billion in cryptocurrency held in its hot wallets, the internet-connected wallets exchanges use to process customer withdrawals. The exchange said it has replenished approximately 90% of the affected assets using company resources and set aside more than $6.34 billion in company funds to cover the theft. Binance pledged to cover all losses for customers and plans to resume withdrawals in phases on November 1, subject to security checks. The phased resumption also provides a concrete date for gauging how quickly the exchange returns to normal operations.

The Bitcoin price recovered some ground from Friday's lows but remained below the $81,000 to $82,000 resistance area identified before the drop. Traders are watching the $76,000 region after the recent decline: a move back above $78,000 would be an initial sign of stabilization, according to chart analysis, while a break below $76,000 could expose lower levels.

The outflows arrived as other major tokens showed deeper declines from their respective recent highs, underscoring the breadth of the retreat. An earlier market comparison put Bitcoin's pullback near 6.5%, while BNB had dropped roughly 14%. Ether had fallen about 20.6% from its cited peak, and XRP about 23%. Those comparisons use different starting points and do not represent identical weekly returns.

BNB traders are watching the $690 area, XRP faces support near $1.20, and Ether's nearby support zone lies between $2,170 and $2,200.
