China Is Third-Largest Contributor To Global Bitcoin Mining: Why It Matters
China was as soon as the undisputed heart for Bitcoin mining. Known for its low cost energy and entry to main {hardware} producers, all of this positioned China as a pacesetter in international Bitcoin mining.
However, this modified when mining was banned by the Chinese government in 2021. In late September 2021, the People’s Bank of China (PBOC) additional banned all cryptocurrency transactions. The PBOC cited the function of cryptocurrencies in facilitating monetary crime in addition to posing a rising threat to China’s monetary system.
Fast-forward to at present—regardless of the federal government’s sturdy efforts to weed out all crypto miners, many have found ways to continue operations. According to the This fall 2025 replace of Luxor’s Global Hashrate Map, China presently accounts for 14.05% of Bitcoin’s complete compute energy, or roughly 145 exahashes per second (EH/s). This is a modest rise from 13.8% in Q3.
China Leads in Global Bitcoin Mining
Kaan Farahani, analysis affiliate at Luxor, informed Cryptonews that Luxor’s Global Hashrate Map estimates the geographic distribution of Bitcoin mining exercise the world over.
“The map offers weighted hashrate focus throughout areas by incorporating mining pool knowledge, ASIC buying and selling flows, and firmware adoption developments,” Farahani stated.
Based on the latest knowledge, China is the third-largest contributor globally to Bitcoin mining, simply behind the U.S. and Russia.
Luxor’s findings don’t present the place particularly the hashrate resides. According to Miner Weekly, a number of sources throughout the ASIC provide chain have pointed to 1 attainable vacation spot, which is Xinjiang. The area’s relative isolation and considerable power assets have made it a longtime hub for Bitcoin mining earlier than China’s ban in 2021.
China Reveals Underground Bitcoin Mining Operations
While China’s continuation of Bitcoin mining could not come as an entire shock, this illustrates the murky, underground nature of the mining business.
Kent Halliburton, CEO and co-founder of Bitcoin mining platform Sazmining, informed Cryptonews that he’s not stunned to see mining nonetheless occurring in China.
“This is likely one of the beauties of Bitcoin mining. It’s a cypherpunk strategy to generate Bitcoin, that means that so long as you have got electrical energy and {hardware}, you may generate Bitcoin for your self. It’s powerful to close down mining on the outskirts, and that’s the reason I consider the hashrate we see in China continues to exist,” Halliburton stated.
Other areas the place Bitcoin mining is taken into account unlawful are additionally displaying indicators of development. For instance, Farahani famous that Luxor’s Hashrate Map offers perception into Iran, estimating that round 8 EH/s of hashrate is operational in the region as of This fall-2025. This represents 0.75% of worldwide market share.
According to Halliburton, Iran is one other good instance of the place Bitcoin mining has been occurring, but has largely been illegal. Iran initially banned Bitcoin mining in May of 2021 for 4 months. The area’s second ban happened in December 2021. Prior to this, Iran’s bitcoin mining was estimated to make up between 4% and eight% of the worldwide BTC community.
“Essentially, any nation with stringent controls on capital outflows is prone to limit or try and ban Bitcoin mining,” Halliburton stated. “But when you’ve got energy, you may generate Bitcoin so long as you have got the best {hardware} to harness it. That signifies that in case you’re making an attempt to stem the circulate of capital from leaving your nation, you have got a method to try this with Bitcoin mining.”
China’s Concerning Mining Infrastructure Empire
In addition to mining, recent findings from Bitcoin options producer Auradine discovered that over 95% of Bitcoin ASIC mining tools is manufactured by Chinese corporations like Bitmain, MicroBT, and Canaan. Auradine’s report notes that Chinese tools manufacturing poses a significant risk to U.S. nationwide safety and key infrastructure.
Sanjay Gupta, chief technique officer at Auradine, informed Cryptonews that China’s mining infrastructure operations are regarding for various causes. For occasion, he talked about that there are over 1,000,000 Chinese-based Bitcoin mining machines with overseas firmware related to the U.S. electrical grid.
“This poses a possible critical cybersecurity threat to {the electrical} grid throughout a number of states,” Gupta stated. “If there’s embedded software program in these Chinese miners that’s triggered for a coordinated cyber assault to drive numerous miners to concurrently go in speedy over- or underdrive, this might trigger a catastrophic failure of the U.S. electrical grid.”
Gupta added that the BTC mining {hardware} provide being extremely concentrated poses a significant threat of a possible 51% takeover of the bitcoin protocol in a hostile geopolitical scenario. This has turn out to be much more of a risk with the latest tariffs imposed on China by President Trump, which could rise to 155% in the coming weeks.
“This may trigger a dramatic impression on the worth of BTC and ripple impact in monetary markets,” Gupta remarked.
Is China A Threat To Bitcoin Miners?
It’s clear that Bitcoin mining and manufacturing proceed to happen in China regardless of bans. So what does this imply for miners primarily based in areas the place BTC mining is taken into account authorized?
According to Farahani, Luxor is unaware of challenges or threats primarily based on China’s mining operations.
On the opposite hand, Gupta believes that Chinese corporations supplying mining tools will create complexities for different areas.
“To fight this, we have to allow sturdy U.S.-based Bitcoin mining suppliers that may drive steady innovation and efficiency for mining operations,” he stated.
Gupta added that shifting ahead, Bitcoin miners ought to have know-how that enables power demand response with the flexibility to quickly enhance or lower energy consumption primarily based on the wants of a state or area’s electrical grid.
In the meantime, the structure and legacy of mining in China will doubtless proceed to loom over the worldwide community. In crypto’s ever‑shifting world, China isn’t gone—however reasonably merely working within the margins.
