[Bitcoin Mining Hashrate Hits Record High in October, Miners' Profits Under Pressure] In October, Bitcoin mining hashrate reached a historic high of 1.13 EH/s, indicating increased participation in mining. However, factors such as rising block difficulty, higher energy prices, and $19 billion in liquidations have squeezed miners' profits. Daily revenue per EH/s dropped by 7% compared to September, falling from $52,000 to $48,000. Meanwhile, the decline in Bitcoin price has reduced miner rewards, with Hashprice dropping nearly 12% this month.
