- China’s prohibition of Bitcoin mining led to a migration of operations to the United States.
- Growing energy consumption and local resistance contrast with the crypto lobby’s push for expansion.
The cryptocurrency landscape in China once flourished, with the nation at the forefront of Bitcoin mining thanks to inexpensive energy and welcoming regulations.
Around 2021, China was the origin for roughly 70% of the globe’s cryptocurrency mining activity. Xi Jinping’s 2019 initiative, which championed the adoption of blockchain tech, boosted China’s market position, surpassing the U.S. in blockchain innovation. But, this all changed drastically in May 2021 when China dramatically altered its digital currency policies.
China’s Cryptocurrency Mining Boom and Bust
The Chinese government’s policy U-turn, banning cryptocurrency mining and exchanges, stemmed from concerns about illicit activities such as money laundering, devastating the industry. According to Zongyuan Zoe Liu, a Council on Foreign Relations senior fellow, the driving force was the potential threat to China’s financial stability. This crackdown forced cryptocurrency miners to seek new locations, with many setting up shop in Kazakhstan, attracted by its abundant and affordable coal-generated power.
Following the ban, Kazakhstan’s share of global cryptocurrency mining exploded to around 20%, rising from 7%, as reported by the Cambridge Bitcoin Electricity Consumption Index. This activity guzzled 7% of the country’s power, resulting in significant fuel price increases and extensive blackouts that impacted the entire nation. By late 2021, widespread public disapproval compelled Kazakhstan to restrict miners’ access to the national electricity grid.
Many cryptocurrency miners then sought refuge in the United States, which quickly rose to become the world’s new Bitcoin mining leader. By 2023, the United States was responsible for over 40% of the world’s Bitcoin “hashrate”, representing the total computing power devoted to mining Bitcoin. US-based mining operations now consume approximately 2% of the nation’s electricity supply, a volume similar to the power consumption of states like Utah or West Virginia. While not leading to energy emergencies on the scale of Kazakhstan, the high energy requirements have sparked local concerns, particularly when Chinese-owned firms establish operations in the US.
One example is Bit Mining, formerly a major cryptomining enterprise in China. After a short stint in Kazakhstan, the company moved to Akron, Ohio. Other companies tend to operate in rural areas where electricity and land are cheaper. However, these establishments have encountered strong resistance from local communities. Citizens in Rockdale, Texas, and Bono, Arkansas, worry about the environmental and noise impact from Bitcoin mining, along with the limited number of jobs created in their areas.
Jeremy Fisher, senior strategy advisor at the Sierra Club, expressed worries about the vast energy demands of Bitcoin mining. To illustrate, a Riot Platforms facility in Texas uses 450 megawatts of electricity, enough to power about 300,000 homes. As climate change concerns grow, Fisher stressed the importance of shifting to renewable energy and the sustainability of Bitcoin mining’s energy requirements.
Environmental Concerns and Energy Use
Local disapproval of Bitcoin mining is widespread. In Murphy, North Carolina, and Massillon, Ohio, residents have created petitions and protests, and launched YouTube channels, to raise awareness of the harmful effects of mining in their regions. In Arkansas, a mother cited the noise’s impact on her autistic child, while Akron, Ohio, residents worry about the added pressure on local resources. Due to strong community opposition, numerous towns, like Harrison, Arkansas, have placed temporary restrictions on new mining locations.
In contrast, a growing pro-Bitcoin lobby has emerged to defend the cryptocurrency industry’s interests. Their efforts have already affected laws in states such as California, where Governor Gavin Newsom vetoed a bill intended to regulate digital financial assets following intense lobbying from the cryptocurrency sector. Lobbying has reached the federal level with over $20 million spent to avoid SEC oversight. Former President Trump, who previously criticized Bitcoin, promised to make the U.S. the “crypto capital of the planet.”
As the Bitcoin industry continues to develop, questions about its centralization become more acute. Originally meant to provide a decentralized alternative to traditional finance, Bitcoin mining has become increasingly concentrated. In 2021, the National Bureau of Economic Research found that 10% of mining operators controlled 90% of the mining capacity, raising concerns about the system’s level of decentralization. As economic competition increases between China and the U.S., lawmakers have started questioning the influence of Chinese-owned mining companies operating within the U.S. borders.
As a response to this geopolitical tension, the Biden administration has started tightening control over foreign-owned mining companies. In May 2023, the President ordered a Chinese-owned mining firm to sell its operations near a nuclear missile site in Wyoming, citing national security threats. This action reveals a growing awareness of the risks linked to foreign ownership in this quickly-expanding industry on US soil.
The Future of Cryptocurrency Mining in the US
The path forward for Bitcoin mining in the United States is uncertain. The Bitcoin lobby is pushing for deregulation and further expansion, while local communities and politicians at all levels are increasingly vocal. As Fisher and other concerned parties are urging stronger controls or moratoriums on new facilities, it remains to be seen if this industry’s expansion will be curbed.
It is clear that if these energy-intensive activities are not properly regulated, they will amplify existing climate concerns, which could lead to a future where the disadvantages of Bitcoin far exceed the benefits.
