China Mining Shutdown Jolts Bitcoin as Hashrate Drops and Miners Sell

Bitcoin’s latest pullback is unfolding alongside renewed pressure on China’s underground mining sector, where a fresh wave of enforcement has abruptly taken large amounts of computing power offline.

In Xinjiang, roughly 400,000 mining machines were reportedly shut down in a short span, cutting off revenue for operators and forcing many to make quick financial decisions. With cash flow disrupted, some miners began selling Bitcoin reserves to cover operating costs or fund relocations abroad.

The shutdowns had an immediate impact on the network. Global Bitcoin hashrate fell by an estimated 100 exahashes per second within 24 hours—about an 8% drop—reflecting the scale of the disruption. The decline surfaced just before Bitcoin slipped to around $86,000 on Tuesday, breaking below the $90,000 level it had defended for most of the prior week.

Market observers see the timing as significant. When miners are suddenly forced offline, the effects often cascade through the market: income disappears overnight, liquidity needs rise, and Bitcoin holdings may be liquidated under pressure. That combination can intensify short-term downside moves, especially when a meaningful share of network power vanishes at once.

The impact was amplified by China’s recent re-emergence in the mining landscape. Less than a month ago, the country had climbed back to become the world’s third-largest source of Bitcoin hashrate, accounting for roughly 14% of the global total by October. Despite the nationwide mining ban introduced in 2021, activity has continued to grow quietly, supported by access to cheap electricity and surplus power in certain regions.

This week’s enforcement push caught many operators off guard. With regulations tightened abruptly, miner revenues quickly came under strain—pressures already worsened by Bitcoin’s roughly 30% drop from its October highs and persistently low transaction fees.

Because mining is central to securing and maintaining the Bitcoin network, sudden disruptions of this scale tend to ripple beyond hashrate metrics alone. While the immediate reaction has been price weakness, the broader effects of China’s latest crackdown may continue to shape market dynamics in the days ahead.
