Key Takeaways<\/strong> The resilience of institutional crypto products faced a harsh reality check this week as investors reacted to the largest crypto hack in history<\/a>. The immediate aftermath of the breach triggered a wave of risk-off sentiment across the digital asset landscape.<\/p>\n \nData from Decrypt<\/em>\u2019s ETF tracker confirms that U.S. spot Bitcoin ETFs<\/a> saw a massive exodus of $643.2 million on Friday. This sell-off represents the most substantial daily outflow observed throughout October. The timing is critical: this was the first full trading session following the discovery of the $6.4 billion exploit on Binance, which began at 4:05 p.m. ET on Thursday-just after the closing bell for U.S. markets. To put this in perspective, the $17.2 million in inflows recorded on Thursday occurred before the scale of the theft was fully realized by the public.<\/p>\n This sudden reversal effectively wiped out the momentum of a four-day winning streak that had previously brought in $441 million. Consequently, the funds are now net negative for the week by approximately $202 million, with the total monthly balance for October dipping to a deficit of roughly $516 million.<\/p>\n \nThe unease is not limited to Bitcoin. Ethereum ETFs have struggled to maintain investor confidence, enduring a five-day streak of outflows that has drained roughly $431 million from the ecosystem. Similarly, Solana-based investment products have felt the pressure, shedding $72 million over the past seven days.<\/p>\n While Bitcoin saw a sharp 4% correction on Friday, it managed to find a floor near $77,520 by Saturday. However, the broader market mood remains fragile. Traders on prediction platforms are increasingly positioning themselves for further downside, reflecting a growing skepticism regarding the near-term recovery of major altcoins.<\/p>\n Myriad: Where does Ethereum go next?
