The post Bitcoin Network Hit by Sudden Mining Shock appeared on BitcoinEthereumNews.com.

Bitcoin Something unusual just happened inside Bitcoin’s infrastructure, and it had little to do with traders pressing the sell button. Over a very short period, a noticeable chunk of computing power vanished from the Bitcoin network. The drop was sharp, measurable, and sudden enough to stand out from the normal ebb and flow of mining activity. Key Takeaways Bitcoin’s network saw an unusually fast drop in hash rate, pointing to a sudden external disruption rather than normal miner behavior The event appears to be linked to regional mining shutdowns, not a structural failure of the network Similar shocks in the past have been absorbed as miners relocate and the network adjusts  While price headlines focused on Bitcoin slipping below a psychological threshold, the deeper signal came from the machines securing the network. An Abrupt Anomaly, Not a Gradual Shift Bitcoin’s hash rate does not usually move in straight lines. Machines are turned on and off constantly as miners respond to energy costs, hardware upgrades, and profitability. What made this episode different was the speed. Rough estimates suggest that close to one-tenth of the network’s computing power disappeared almost at once. To reach that scale, an enormous number of machines would have had to shut down simultaneously – something that rarely happens without an external trigger. Mining executives quickly flagged the move as abnormal, pointing out that routine maintenance or marginal economics cannot explain such a concentrated event. Geography Matters Again Attention soon shifted to one of Bitcoin mining’s former strongholds: western China. Despite the country’s nationwide ban on mining, pockets of infrastructure have historically remained active, operating under varying local conditions. Industry insiders believe the recent drop may reflect a localized disruption rather than a new nationwide policy shift. Regional enforcement, power constraints, or administrative pressure could all produce a…
