Bitmain: The Rise, Struggles, and Evolution of a Cryptocurrency Mining Giant

·

Bitmain Technologies Ltd., commonly known as Bitmain, is a Beijing-based semiconductor company that has played a pivotal role in shaping the global cryptocurrency mining industry. Founded in 2013 by Wu Jihan and Zhan Kecuan, Bitmain quickly rose to dominance by designing specialized ASIC (Application-Specific Integrated Circuit) chips for Bitcoin mining. Over the years, the company expanded into artificial intelligence (AI) hardware, cloud mining services, and blockchain infrastructure—becoming one of the most influential players in the digital asset ecosystem.

Despite its early success, Bitmain faced internal conflicts, regulatory pressures, and shifting market dynamics that tested its resilience. This article explores Bitmain’s journey—from its founding and rapid growth to leadership battles, strategic pivots, and ongoing evolution in the face of global technological and geopolitical challenges.

Founding and Early Innovations

Bitmain was co-founded in 2013 by Wu Jihan, a financial analyst with a deep interest in Bitcoin, and Zhan Kecuan, an entrepreneur with experience in IP networking. Their vision was clear: build high-efficiency mining hardware to capitalize on the growing demand for Bitcoin mining power.

In late 2013, Bitmain launched its first product: the ANTMINER S1, delivering a hash rate of 180 GH/s. This marked the beginning of a new era in mining efficiency. Just months later, the ANTMINER S2 pushed performance to 1 TH/s, setting a benchmark for future models.

By focusing on ASIC technology—custom chips optimized solely for mining—Bitmain gained a significant edge over general-purpose GPU miners. The company vertically integrated its operations, handling chip design, firmware development, manufacturing, and global distribution under one roof.

Market Dominance and Financial Success

By 2018, Bitmain had become the world’s largest supplier of Bitcoin mining ASICs. That year, it reported $742.7 million in net profit** during the first half alone, with annual revenues reaching approximately **$2.5 billion in 2017. At its peak, the company accounted for over 70% of the global market share in mining hardware.

Beyond hardware, Bitmain operated two major mining pools:

As of recent data, these pools command around 10.57% of Bitcoin’s total network hash rate and nearly 38.37% of Bitcoin Cash’s, giving Bitmain substantial influence over consensus and transaction validation.

The company also launched Hashnest, a cloud mining platform serving over 400,000 users, allowing individuals to participate in mining without owning physical equipment.

In recognition of its valuation and impact, Bitmain was ranked:

Strategic Expansion into AI and Global Operations

Recognizing the parallels between cryptocurrency mining and machine learning computations, Bitmain began investing heavily in artificial intelligence chips in 2017. That year, it secured $50 million in funding from Sequoia Capital and IDG Capital to accelerate AI research.

The company developed the Sophon series of AI inference chips, targeting applications in surveillance, autonomous driving, and edge computing. While this expansion showed promise, AI never reached the profitability levels of its core mining business.

Geographically, Bitmain established offices in Israel, the Netherlands, and Texas. However, following market downturns and internal restructuring, it scaled back operations abroad—closing overseas offices and reducing its U.S.-based mining footprint.

Internal Conflict: The Wu vs. Zhan Power Struggle

One of the most turbulent chapters in Bitmain’s history unfolded between 2019 and 2021—a period marked by a bitter founder dispute between Wu Jihan and Zhan Kecuan.

In October 2019, Wu, then chairman of the board, abruptly removed Zhan from all executive roles and changed the legal representative status in official registrations. Zhan contested the move through legal channels, leading to a series of lawsuits, administrative appeals, and even physical confrontations over control of company seals and offices.

This conflict culminated in May 2020 with a dramatic incident dubbed the “battle for the business license,” where both sides sent teams to seize control of Bitmain’s Beijing headquarters.

After prolonged negotiations mediated by investors, a settlement was reached in January 2021:

The fallout significantly impacted Bitmain’s valuation, dropping from an estimated $8 billion at its peak** to around **$3 billion post-split. Its long-delayed IPO ambitions were also derailed.

Regulatory Challenges and Market Adjustments

In June 2021, China intensified its crackdown on cryptocurrency activities. Mining operations were banned, and financial institutions were prohibited from facilitating crypto transactions.

In response, Bitmain paused sales of new miners in global spot markets to manage inventory pressure as miners rushed to sell off equipment. While it continued supporting existing customers, this regulatory shift forced a reevaluation of its operational model.

Many Chinese miners relocated to North America, Central Asia, and the Middle East—regions with favorable energy policies. Bitmain adapted by strengthening partnerships with international hosting providers and exploring opportunities in compliant blockchain infrastructure.

Subsidiary Sanctions and Geopolitical Tensions

In January 2025, Bitmain’s subsidiary Sophon (Sui Neng Tech) was added to the U.S. Department of Commerce’s Entity List for allegedly violating export controls by facilitating the transfer of advanced TSMC-made semiconductors into China.

Reports suggest Sophon-designed chips were found inside Huawei’s Ascend 910B AI processor during a teardown by TechInsights. Although Sophon denied any direct or indirect collaboration with Huawei, Reuters cited sources confirming TSMC suspended shipments after identifying design similarities.

This development highlights the growing intersection between semiconductor innovation, national security concerns, and U.S.-China tech rivalry.

Frequently Asked Questions (FAQ)

Q: What does Bitmain do?

A: Bitmain designs and manufactures specialized ASIC chips used primarily for cryptocurrency mining. It produces the popular ANTMINER series of mining rigs and operates major mining pools like ANTPOOL and BTC.com. The company has also ventured into AI chip development through its Sophon brand.

Q: Who owns Bitmain now?

A: As of 2021, Zhan Kecuan regained full control of Bitmain following a settlement with co-founder Wu Jihan. Wu left the company and now leads Bitdeer, a separate entity focused on cloud mining services.

Q: Is Bitmain still profitable?

A: While exact figures are private post-IPO withdrawal, industry estimates suggest Bitmain remains profitable due to continued demand for efficient mining hardware. Revenue projections in 2021 placed its valuation between $8–9 billion.

Q: Why did Bitmain stop selling miners?

A: In mid-2021, Bitmain temporarily halted retail sales of miners in response to China’s nationwide crypto mining ban. This led to oversupply concerns and strategic inventory management rather than permanent discontinuation.

Q: Are Bitmain miners compatible with all cryptocurrencies?

A: Most ANTMINER models are designed specifically for SHA-256-based coins like Bitcoin and Bitcoin Cash. They are not suitable for mining Ethereum (pre-Merge), Litecoin (Scrypt-based), or other algorithms without dedicated hardware versions.

Q: Can individuals still mine Bitcoin using Bitmain devices?

A: Yes—individuals can purchase ANTMINER units for personal use. However, profitability depends heavily on electricity costs, network difficulty, cooling infrastructure, and access to reliable internet connectivity. Many users opt for hosted or cloud mining solutions instead.

Final Outlook

Bitmain’s story reflects the broader trajectory of the cryptocurrency industry—marked by explosive growth, fierce competition, regulatory uncertainty, and technological transformation.

While no longer the unchallenged leader it once was—with competitors like MicroBT gaining ground—the company continues to innovate within both blockchain and AI domains. Its ability to adapt through leadership crises, geopolitical headwinds, and market cycles demonstrates remarkable resilience.

As digital assets evolve toward greater institutional adoption and energy-efficient consensus mechanisms, companies like Bitmain must continue reinventing themselves—not just as hardware makers, but as key enablers of decentralized infrastructure.
