Bitcoin enthusiasts see cryptocurrency as beyond the reach of any government. Yet up to three-quarters of the world’s supply has been produced in a single country, China, where government pressure to cut production is now causing global turbulence over bitcoin.
The amount of electricity needed to power a large number of computers used to create new bitcoin is at odds with China’s recent climate goals. The government, which runs its national currency with a clenched fist, also frowns on cryptocurrency in general. No legal bitcoin exchange has been allowed in China for years, although the country’s entrepreneurs have become the dominant source of its output.
Few governments have embraced bitcoin, but the fallout from threats from Beijing has demonstrated just how vulnerable its grip on production has made cryptocurrency.
Calculating the 24/7 numbers required to create or mine bitcoin relies on a sufficient supply of cheap electricity and equipment, some of the same things China has tapped into to become the global manufacturing hub.
In their thirst for market share, Chinese bitcoin miners have taken advantage of an under-regulated and oversized power generation industry. They have set up mining operations alongside hydropower producers in the mountainous provinces of Sichuan and Yunnan, where turbines turn snowmelt and seasonal downpours into electricity. When the river flow slackened each winter, the miners packed their computers and headed north, to coal-rich Xinjiang and Inner Mongolia.

Mining operations in China, sometimes tens of thousands of computers wired together to solve complex computer puzzles, are gorging themselves with electricity. The bitcoin industry alone is on track to rank among China’s top 10 energy users, alongside sectors like steel and cement production, according to a peer-reviewed article published in April by Britains Nature Communications. This would make Chinese bitcoin producers bigger consumers of energy than the entire Italian nation.
This voracious appetite has put bitcoin mining at odds with Beijing’s political priorities. President Xi Jinping is determined to make China a climate champion and has set ambitious goals to reduce coal consumption. Beijing is also set to launch a national digital currency, controlled by the central bank and designed to counter cryptocurrencies.
China’s bitcoin production is reminiscent of the influence of nations in other high-tech fields, from the production of rare earth mineral materials to CCTV equipment with one main difference: Beijing’s distrust of cryptocurrencies.
On May 21, the Chinese government pledged to crack down on bitcoin mining and trading behavior, a statement widely interpreted as a warning that the days of multibillion-dollar cryptocurrency supply chains are counted.
In response, power producers are ejecting miners from the grids, and Chinese dealers are unloading computers designed to create second-hand bitcoins at very cheap prices.
Brewing production
None of this means the world will run out of bitcoin. Instead, mining is expected to slow down in China and accelerate elsewhere. Miners in other countries had already reduced the dominance of Chinese production in the past 18 months or so, according to figures from the University of Cambridge, which estimated that the United States’ share had increased to about 7%. ‘last year.
But even amid some industry expectations that the US’s share could grow to perhaps 40% in the next few years, the bitcoin community believed China would retain nearly half of the mining. .
In China, it was always thought the government was going to crack down, said Nishant Sharma, founding partner of Beijing-based consulting firm BlocksBridge Consulting Ltd.
Yet he said: I see so much panic.
Concerns over the turmoil in China weighed on the price of bitcoin, along with the announcement last month that automaker Elon Musks Tesla Inc. had stopped accepting it as payment, also due to environmental concerns.
The first entrants
Bitcoin history in China owes a lot to the earthquake that rocked southwestern Sichuan province in 2013. Among the millions of donations that flowed to charities in the aftermath, some stood out: donation of bitcoins to a foundation of Jet Li, the Chinese star of the action.
The resulting buzz about bitcoin intrigued Jiang Zhuoer, an employee of a telephone company in Shanghai, who that winter bought two computers and started operating at his home. His installation quickly generated $ 500 to $ 700 per month and also heated his apartment, he recalls in an interview.
Also that year, a team of tech enthusiasts in Beijing began designing computers specifically for creating new bitcoin. Their company, Bitmain Technologies Ltd., used parameters published by an unidentified Bitcoin architect, which one of them translated into Chinese.

Chinese regulators shocked by a series of financial manias and the crises that inevitably followed have telegraphed anxiety. The government’s state-controlled news agency Xinhua has only dubbed bitcoin as privately-made money circulating on the internet.
Eight months after Jet Li’s donations, regulators torpedoed any notion that the buzzword was welcome in China’s financial system. Led by the People’s Bank of China, Beijing has banned the country’s banks from handling cryptocurrency.
Beijing tightened the screws in 2017 by banning various uses of the cryptocurrency, including its online exchange.
Chinese authorities, however, did not set any specific policies on bitcoin production, so enthusiasts continued to mine.
Inspired by calculations deep in the profit envelope, instead of technical knowledge, real estate moguls and small-town factory owners have reconstituted cheap warehouses into data farms, taking hold of Shenzhen electronics and stacking computer servers on raw racks with noisy cooling. Fans.
In the movies, they’re cleaner and more presentable, BlocksBridges Mr. Sharma said. In China, they are not that clean and the jungle of threads is worse.
Since mining cryptocurrency involves solving increasingly difficult mathematical problems, each new unit of the crypto requires more computational time and energy than the one mined before it. This means that the earliest and most aggressive growers had a huge advantage.
Bitcoin was a windfall for owners of power plants, often regional governments in capricious places that had increased their production capacity on the basis of fragile projections of industrial demand.
Revenue-hungry power producers have billed themselves as big data centers, like the Sichuans Aer III hydropower plant on the Tibetan Plateau, which in 2019 began hosting 1,750 bitcoin mining machines on its land. . Miners have occasionally stolen electricity, including one who was convicted of hijacking power lines to take electricity worth $ 125,000 in six months to run his more than 400 bitcoin machines . He was sentenced in 2019 to 11 years in prison by a court in Northern Liaoning Province.
Some of China’s biggest winners have focused on servicing the Minersa model, followed in the mid-1800s by Levi Strauss, who became wealthy outfitting prospectors during the California Gold Rush.
Bitmain, for example, has become the world’s largest producer of mining computers by developing chips optimized to handle the equations that create cryptocurrency. Shanghai’s wealth-tracking service Hurun Report has crowned three of Bitmains’ major shareholders as billionaires, including Zhan Ketuan, 42, with an estimated net worth of over $ 15 billion.
The telephone company worker turned miner, Mr. Jiang, is now the general manager of megaminer BTC.Top, a pool of 400,000 machines. The 36-year-old says the latest guidelines from Beijing could herald a return to smaller-scale data centers and decentralized production, and he plans to export some equipment to North America or Central Asia .

How might a shift to the US for bitcoin mining affect US climate goals? Join the conversation below.
Industry supporters in the West say mining is losing its cowboy image and momentum is shifting to countries with more predictable regulatory regimes, particularly the United States. The Internal Revenue Service has cryptocurrency policies, US banks are providing custody services for bitcoin, and utilities are inviting miners to visit natural gas-fired power plants in the upstate of New York and solar farms in Texas.
Beijing’s crackdown is expected to improve the long-term outlook for currencies by reducing market fear, uncertainty and doubt that China is mining all bitcoin, said Sue Ennis, head of business development at the company. cryptocurrency Hut 8 Mining Corp. China sees this as an opportunity to capture a bigger slice of the pie, she said, noting that her company is adding additional capacity to accommodate minors wishing to leave China.
In one of Bitmain’s largest overseas orders to date, Las Vegas-based Marathon Digital Holdings Inc. has ordered 70,000 machines that it is installing at bitcoin farms in Hardin, Mont., And Big Spring, Texas.
Before now, the mantra of bitcoin mining was: what is the cost of production in China and what is the risk? says Marathons CEO Fred Thiel. Now, with the crackdown underway, he said, the risk has become evident.
