China has long been home to more than half the world’s bitcoin miners, but now, Beijing wants them out ASAP.
In May, the government called for a severe crackdown on bitcoin mining and trading, setting off what’s being dubbed in crypto circles as “the great mining migration.” This exodus is underway now, and it could be a game changer for Texas.
Mining is the energy-intensive process which both creates new coins and maintains a log of all transactions of existing digital tokens.
Despite a lack of reserves that caused days-long blackouts last winter, Texas often has some of the world’s lowest energy prices, and its share of renewables is growing over time, with 20% of its power coming from wind as of 2019. It has a deregulated power grid that lets customers choose between power providers, and crucially, its political leaders are very pro-crypto – dream conditions for a miner looking for a kind welcome and cheap energy sources.
“You are going to see a dramatic shift over the next few months,” said Brandon Arvanaghi, previously a security engineer at crypto exchange Gemini. “We have governors like Greg Abbott in Texas who are promoting mining. It is going to become a real industry in the United States, which is going to be incredible.”
China’s mining dominance
2021 data for the global distribution of mining power is not yet available, but past estimates have shown that 65% to 75% of the world’s bitcoin mining happened in China – mostly in four Chinese provinces: Xinjiang, Inner Mongolia, Sichuan, and Yunnan. Sichuan and Yunnan’s hydropower make them renewable energy meccas, while Xinjiang and Inner Mongolia are home to many of China’s coal plants.
Castle Island Ventures founding partner Nic Carter says that while it’s not totally clear how China will handle next steps, it a phased rollout is likely. “It seems like we’re going from policy statement to actual implementation in relatively short order,” he said.
The way this exodus is measured is by looking at hashrate, an industry term used to describe the computing power of all miners in the bitcoin network.
“Given the drop in hashrate, it appears likely that installations are being turned off throughout the country,” continued Carter, who also thinks that probably 50 to 60% of bitcoin’s entire hashrate will ultimately leave China.
Although China’s announcement hasn’t been cemented in policy, that isn’t stopping miners like AlejandroDe La Torre from cutting their losses and making an exit.
“We do not want to face every single year, some sort of new ban coming in China,” said De La Torre, vice president of Hong Kong-headquartered mining pool, Poolin. “So we’re trying to diversify our global mining hashrate, and that’s why we are moving to the United States and to Canada.”
One of bitcoin’s greatest features is that it is totally location agnostic. Miners only require an internet connection, unlike other industries that must be relatively close to their end users.
“The cool thing about bitcoin that is under appreciated by a lot of the naysayers is that it’s a portable market; you can bring it right to the source of energy,” explained Steve Barbour, founder of Upstream Data, a company that manufactures and supplies portable mining solutions for oil and gas facilities.
That said, the exodus won’t be instantaneous, in part, because it will take miners some time to either move their machines out of China or liquidate their assets and set up shop elsewhere.
Where they’re going
Because miners at scale compete in a low-margin industry, where their only variable cost is typically energy, they are incentivized to migrate to the world’s cheapest sources of power.
“Every Western mining host I know has had their phones ringing off the hook,” said Carter. “Chinese miners or miners that were domiciled in China are looking to Central Asia, Eastern Europe, the U.S., and Northern Europe.”
One likely destination is China’s next-door neighbor, Kazakhstan. The country’s coal mines provide a cheap and abundant energy supply. It also helps that Kazakhstan has a more lax attitude to building, which bodes well for miners who need to construct physical installations in a short period of time.
Didar Bekbauov runs Xive, a company that provides hosting services to international miners. Xive also sells the specialized equipment needed for mining.
Bekbauov says that he’s stopped counting the number of Chinese miners who have called him to ask about relocation options, ranging from operations with 15 rigs to thousands.
“One miner told us that only government electricity plants have restricted mining and private ones will continue to service miners,” Bekbauov told CNBC.
“But most of the electricity is generated by government power plants, so miners will have to move. That makes them uncertain and desperate to find other locations,” he said.
Whether Kazakhstan is a destination or simply a stopover on a longer migration west remains to be seen.
Arvanaghi is bullish on North America and thinks the hashrate there will grow over the next few months.
“Texas not only has the cheapest electricity in the U.S. but some of the cheapest in the globe,” he said. “It’s also very easy to start up a mining company…if you have $30 million, $40 million, you can be a premier miner in the United States.”
Wyoming has also trended toward being pro-bitcoin and could be another mining destination, according to Arvanaghi.
There are, however, a few major limitations to the U.S. becoming a global mining destination.
For one, the lead time to build the actual physical infrastructure necessary to host miners is likely six to nine months, Carter told CNBC. “The U.S. probably can’t be as nimble as other countries in terms of onshoring these stray miners,” he said.
The move logistics may also prove difficult. There is a shipping container shortage, thanks to the tailwinds of the Covid pandemic.
But perhaps the biggest question is the reliability of the Texas power grid. A storm that devastated large swaths of the state in 2020 has reignited a debate over whether Texas should winter-proof its systems, a potentially costly project that might affect taxes or other fees for those looking to tap into the state’s power grid. More recently, ERCOT, the organization that operates Texas’ grid, asked consumers to conserve energy amid what officials called an unusual number of “forced generation outages” and an upcoming heat wave.
Answering the Musk critique
Tesla CEO Elon Musk has bashed bitcoin mining, claiming that it is bad for the environment. It’s not a new criticism.
For years, skeptics have maligned the world’s most popular digital token for polluting the planet, while supporters have extolled the virtues of bitcoin and its role in accelerating the rise of renewable energy.
It is unclear whether the China mining exodus will make or break the case for bitcoin enthusiasts in the debate around the token’s carbon footprint. The dominant narrative, to date, has been that much of the world’s bitcoin is mined with Chinese goal.
“From a narrative perspective, it’s definitely an improvement,” said Carter. “But China also has the most abundant stranded hydro resources in the world.”
The country offers significant energy vectors from wind, solar, and especially hydropower in the south. Xinjiang’s grid, for example, is 35% powered by wind and solar energy inputs.
If all the miners do end up leaving China, it will mean less fossil fuel-powered mining, but it will also mean that the network’s share of renewable energy-powered mining will drop. This is why the question of where these migrant miners end up could prove critical to bitcoin’s future. “It’s the biggest story of the year for bitcoin,” said Carter.
De La Torre says they’re looking to expand operations using green energy, a trend that is already years in the making. He says that hydro plants are generally cheaper than fossil fuels in most parts of the world.
“Mining is price sensitive, so as to seek out the lowest cost power and the lowest cost power tends to be renewable because if you’re burning fossil fuels…it has extraction, refinement, and transport costs,” explained Blockstream CEO Adam Back.
Lazard
Each year, investment bank Lazard releases a breakdown of energy costs by source. Its 2020 report shows that many of the most common renewable energy sources are either equal to or less expensive than conventional energy sources like coal and gas. And the cost of renewable power keeps going down.
But there are limitations to running crypto mines purely on renewable energy.
Though solar and wind are now the world’s least expensive energy sources, both power supplies face limitations at scale, so there is concern over the viability of miners turning exclusively to wind or solar energy.
Next six months
For the time being, there isn’t that much mining capacity worldwide that is ready to absorb the Chinese miner diaspora. While they scramble to find a new home, we could see hashrate go offline – and stay offline.
In practice, that would mean all the remaining miners are more profitable for a period of time.
Having more geographic dispersion would even out the global balance of power, and it would also reduce the ability of any one sovereign nation to co-opt or control the network.
We may also see special crypto economic zones pop up in the next few months.
“You will see jurisdictions adopting a very favorable stance and creating the equivalent of special zones to encourage miners to host locally,” said Carter. “We’re seeing it at the state level here. You’re also gonna see it at the country level, you might even see subsidized electricity for mining.”
Multi-million-dollar grants adding up to more than $46 million from the US Federal Highway Administration (FHWA) will help support electrification efforts at several American ports.
The Long Beach Container Terminal (LBCT) in Long Beach, California has received a $34.9 million grant from the FHWA to replace 155 on-site commercial trucks and buses with zero-emission vehicles (ZEV). The grant will fund both the purchase of new electric trucks and the necessary charging infrastructure to support them.
LBCT said the grant dollars will allow it to continue its multi-billion dollar investments in more sustainable logistical operations. “Our vehicle electrification project, coupled with previous investments, enables LBCT to achieve a unique status that is reframing the way the world views sustainable goods movement, enhancing community quality of life and climate change,” said Anthony Otto, CEO of LBCT.
“This investment is a huge win for clean air, electrification and the region,” said US House Rep. Robert Garcia. “These federal dollars will make our port cleaner, safer and help us meet our climate goals.”
Container ports used to be some of the dirtiest, most heavily polluted areas in the world. That was bad for everyone – but it was especially bad for the people who lived and worked near them. That’s why any positive change is good. Beyond just “positive change,” however, ports today seem to be leading the way when it comes to electric vehicle and hydrogen adoption.

German equipment manufacturer Kramer showed off a pair of zero-emission equipment options at the Paris Intermat show last week – the 5065e electric wheel loader and 1445e electric telehandler.
Kramer says the quiet operation of its new electric wheel loader and telehandler are ideal for noise-sensitive areas such as city centers, cemeteries and golf courses, hotels, and suburban parks and recreation areas, where it can operate without emitting harmful diesel particulate matter and other forms of air pollution.
Kramer-Werke GmbH is serious about promoting its new EVs in the French market. “That’s why Intermat is an important platform for us,” explains Christian Stryffeler, Kramer’s Managing Director. “We are also looking forward to showcasing our new generation of (electric) wheel loaders and telescopic wheel loaders here.”
Kramer 5065e wheel loader
The 5065e loader is powered a 37.5 kWh, 96V lithium-ion battery that’s good for up to four hours of continuous operation – which is a lot more than it sounds, considering idle time in an EV doesn’t drain batteries the way idling a diesel drains fuel. A 23 kW (30 hp) electric motor drives the electric wheel loader around the job site, while a 25 kW (approx. 35 hp) motor powers the machine’s 40 liters hydraulic system.
Kramer says the battery on its electric loader can be fully charged in just 5.1 hours using a “Type 2 Wallbox” (that’s an L2 charger to you and me). Max payload is 1750 kg, with a 2800 kg tipping load. Top speed is 20 km/h (approx. 12.5 mph).
Kramer 1445e telehandler
The 1445e telehandler uses a 96V battery architecture that’s similar to the one in the wheel loader, but in a smaller 18 kWh or 28 kWh pack. This enables a fleet manager to right-size their equipment’s batteries to provide four hours of run time in different types of work environments. And, also like the wheel loader, a 23 kW (30 hp) electric motor provides the drive while a 25 kW (approx. 35 hp) powers the hydraulics.
Level 2 charging comes standard on Kramer’s electric telehandler, enabling a full charge of the larger, 28 kWh battery in about five hours. Max payload is 1450 kg.
Electrek’s Take
It’s always good to see more manufacturers pushing out electric equipment options. It’s still the “wild west” out there, even more so than in automotive, and Kramer’s offerings seem to be a step behind in some ways (no DCFC capability) and ahead in others (96V where others are 48V), so it’s hard to know where they stand.
The robotics experts at ETH Zurich have developed an autonomous excavator that uses advanced AI to help it complete high-skill tasks without a human operator.
Dry stone wall construction typically involves huge amounts of operator labor. Doing it right requires not just hours of labor, but hours of skilled, experienced labor. At least, it used to. If the crew at ETH is successful, building stone retaining walls will soon become a “set it and forget it” task for robots to complete. Robots like their HEAP excavator.
HEAP (Hydraulic Excavator for an Autonomous Purpose) is a customized Menzi Muck M545 developed for autonomous operation that uses electrically-driven hydraulics to operate an advanced boom arm equipped with draw wire encoders, LiDAR, Leica iCON site-mapping, and a Rototilt “wrist” on the end that makes it look more like a high-precision robotic arm than a traditional heavy equipment asset.
ETH HEAP tech stack
Which makes sense. After all: the ETH guys are roboticists, not skilled heavy equipment operators. So, how does their robot do against skilled operators?
“We are currently outperformed by human excavator operators in placement speed,” ETH researchers wrote in Science Robotics. “Such operators, however, typically require string and paint references with which to register their construction and often a second or third person outside the machine to provide guidance and to insert small supporting stones, gravel, and soil by hand and shovel. In contrast, our process can build complex nonplanar global surface geometries without physical reference markers, does not require a skilled driver or small supporting stones, and provides a full digital twin of the built structure for better accountability and future reuse.”
Translation: the robot is slower, but it gets the job done.
You can watch the ETH HEAP put all its onboard tech to work building a 215 foot long, 20 foot high retaining wall all on its own in the video, below.
Autonomous excavator constructs dry stone wall
The completed project can be seen at Circularity Park in Oberglatt, Switzerland, and illustrates the potential for autonomous equipment to build with irregularly-shaped materials. And with skilled operators in short supply everywhere, the potential to free up operators so they can go where they’re really needed.
That said, the electrically driven hydraulics and high-precision Rototilt wrist on the end of the boom arm’s “claw” alone make this futuristic excavator worth some attention. As more and more manufacturers switch to full electric or even “just” electric drive, research into better solutions for existing hydraulic equipment and expertise could lead to big market wins.
