Why the ‘great China Bitcoin mining crackdown’ fell short of early claims

Recent claims of a major Bitcoin mining crackdown in China’s Xinjiang region rippled through the digital asset industry this week, but data by TheMinerMag suggests the actual impact was far smaller than early narratives implied.

According to the latest Miner Weekly report, the Bitcoin network initially experienced a short-term hashrate decline, which was linked to developments in Xinjiang. However, the drop also coincided with power curtailments in the United States.

Most major mining pools recovered to near pre-dip levels within days, resulting in a net decline of roughly 20 exahashes per second, which is significantly lower than the approximately 100 EH/s loss cited in early reports. “That points to a largely temporary disruption rather than a sustained, region-specific shutdown,” the report said.

The distinction is meaningful for assessing Bitcoin’s security and miner activity. While large, sustained hashrate declines can affect block production and mining difficulty, overstating the role of a single regional event risks distorting views of global mining dynamics and exaggerating geopolitical exposure.

Data from TheMinerMag shows that the largest pool-level declines during Monday’s disruption came from North America, with Foundry USA alone reporting an estimated 180 EH/s drop in hashrate.

While Chinese-origin mining pools recorded combined declines of about 100 EH/s, “attributing the entire drop to Xinjiang would be a stretch,” the report said.

So, what happened in China?

Reports of a renewed Bitcoin (BTC) mining crackdown in China surfaced this week after Jianping Kong, a former executive at hardware producer Canaan, said that some operations in the Xinjiang region had been shut down.

Early estimates circulating on social media suggested that as many as 400,000 to 500,000 mining machines may have gone offline.

Subsequent reporting and industry analysis, however, indicated that the disruptions were more likely tied to compliance or operational issues rather than a broad, coordinated enforcement campaign.

Beyond the brief hashrate dip, Bitcoin mining activity linked to China has resurfaced in recent years, despite the country’s nationwide ban in 2021. Data from CryptoQuant suggests China may account for roughly 15% to 20% of global Bitcoin mining activity.

Xinjiang, in particular, has attracted miners due to its abundant and relatively low-cost energy supply. At the same time, local governments have invested heavily in data center infrastructure, with some facilities reportedly leasing excess capacity to Bitcoin miners to help offset cyclical declines in demand from other computing workloads.
