Bitcoin dropped below $81,000 and Ethereum fell near $2,400, with the top ten cryptocurrencies turning red over seven days. Spot Bitcoin funds saw $484.9 million in outflows on Wednesday, followed by another $244 million yesterday, bringing October's total net outflow to $400 million. Ethereum funds have bled $640 million over eight consecutive sessions. Decrypt attributes the downturn to factors including Bitmine's impending halt of Ethereum purchases, Ethereum funding rates turning negative, and rising oil prices due to attacks on Iranian tankers. However, major cryptocurrencies have rebounded in the past 12 hours, with Bitcoin back above $82,000 and Ethereum nearing $2,500, suggesting a leverage flush rather than a collapse ahead of the "10/10" anniversary.
