Bitcoin has come a long way since its inception in 2009, evolving from a niche digital experiment to a global financial phenomenon. What started as a quirky transaction—10,000 BTC for two pizzas—has transformed into a reality where a single coin can buy hundreds of pizzas. This meteoric rise has created unprecedented wealth for early adopters, particularly those who entered the space through mining.
Among these pioneers, one name stands out: Wu Jihan, the 85s CEO of Bitmain, who has quietly risen to become one of the most influential figures in the cryptocurrency ecosystem. While he remains tight-lipped about his personal holdings, industry speculation suggests he may be the richest individual on the Bitcoin blockchain, controlling over 110,000 BTC.
But how did a non-technical graduate with a background in psychology and economics come to dominate the world’s most decentralized network? The answer lies in hardware, timing, and strategic vision.

The Bitcoin Gold Rush Begins
The surge in Bitcoin's price triggered a modern-day gold rush. Miners—once hobbyists running GPUs from their homes—became industrial-scale operations. At the heart of this transformation was Bitmain, whose Antminer series quickly became the go-to hardware for serious miners.
Mining is essentially a competitive process. Every 10 minutes, a new block is added to the blockchain, and the miner who solves the cryptographic puzzle first earns the block reward—currently 12.5 BTC. As more participants join, competition intensifies, making it nearly impossible for individual miners to succeed alone.
This is where mining pools come in. By combining computational power, miners increase their odds of earning rewards. Bitmain operates two of the largest pools—BTC.com and Antpool—controlling approximately 30% of global Bitcoin hash rate. That means roughly one in every three blocks mined worldwide comes from machines coordinated through Bitmain’s infrastructure.
For perspective: a single Antminer S19 consumes about 31.2 kWh per day and produces around 1.34 BTC annually. At $30,000 per BTC, after electricity costs, it can generate over $16,000 in net profit yearly—assuming stable prices and efficient operations.
Many mining farms are located in regions like Sichuan and Inner Mongolia, where electricity is cheap and labor costs minimal. A 3,000-machine facility managed by just 10 people could generate over $5 million in annual net profits under favorable conditions.

From Dorm Room to Dominance: The Rise of Bitmain
Founded in 2013 by Wu Jihan and Zhan Ketuan—a chip design expert from the Chinese Academy of Sciences—Bitmain entered a crowded market dominated by early players like Butterfly Labs. Yet, through superior engineering and supply chain control, it quickly outpaced competitors.
Wu’s strength wasn’t technical expertise but vision and execution. He recognized that profitability hinged on three key metrics: power efficiency, processing speed, and failure rate. Bitmain focused relentlessly on optimizing these through proprietary ASIC chips designed in-house and manufactured via partnerships with TSMC in Taiwan and assembly plants in Shenzhen.
When the 2014 bear market wiped out weaker rivals, Bitmain survived due to disciplined financial management and continuous innovation. Then came the game-changer: the fifth-generation Antminer in 2015. With significantly improved performance, it captured market share rapidly and cemented Bitmain’s dominance.
Today, machines produced by Bitmain control over 70% of global Bitcoin mining power. This gives the company outsized influence—not just economically, but also in shaping protocol-level decisions.

The Power Behind the Protocol
With such concentrated hash power, questions arise: Can Bitmain—or Wu Jihan—dictate Bitcoin’s future?
Critics point to Bitmain’s role in the 2017 Bitcoin Cash (BCC) fork as evidence of undue influence. BCC emerged as a hard fork aimed at increasing block size, a change favored by miners seeking higher transaction fees. Many believe Wu orchestrated support for BCC through his mining pools, leveraging Antpool’s vast network to sway consensus.
Samson Mow, a prominent blockchain figure from the U.S., accused Wu of attempting to centralize control over Bitcoin’s development. However, Wu maintains that no one can force adoption—new coins only gain value if users choose them freely.
Still, Bitmain’s vertical integration is undeniable. It manufactures mining hardware, runs large-scale mining farms (including a major facility in Ordos, Inner Mongolia), and operates leading mining pools. This end-to-end control creates both efficiency and concern about centralization risks in a system built on decentralization.
Yet experts like Tian Jia, an early miner since 2011, argue that centralization is inevitable. “Mining will always trend toward concentration,” he says. “Efficiency wins. Someone was bound to dominate.”
Frequently Asked Questions (FAQ)
Q: How much Bitcoin does Wu Jihan actually own?
A: Exact figures are unknown. Wu has never disclosed his personal holdings. However, estimates based on blockchain data and Bitmain’s operations suggest he could control over 110,000 BTC.
Q: Is Bitmain still profitable today?
A: Yes. Despite market fluctuations, Bitmain reported over $1 billion in net profit during the first half of 2025 alone, driven by strong demand for efficient mining equipment.
Q: Can one company really control Bitcoin?
A: No single entity fully controls Bitcoin due to its decentralized nature. However, companies like Bitmain can exert significant influence through hash power and ecosystem presence.
Q: Why are mining farms located in Inner Mongolia or Sichuan?
A: These regions offer low electricity costs—often from surplus hydro or coal power—and favorable climate conditions for cooling hardware.
Q: What happens when all Bitcoin is mined?
A: After approximately 2140, no new BTC will be created. Miners will rely solely on transaction fees for income, which may reshape mining economics.
Q: Is Bitmain transitioning to AI as rumored?
A: Wu has mentioned exploring AI applications using their chip design capabilities. However, no official shift has occurred yet—mining remains their core business.

The Future of Mining and Beyond
While Bitmain thrives today, challenges loom ahead. Regulatory scrutiny, environmental concerns, and shifting market dynamics add uncertainty. Wu acknowledges that long-term sustainability depends on broader adoption and price stability.
Still, Bitmain’s story exemplifies how strategic positioning in emerging technologies can yield extraordinary outcomes. From humble beginnings to controlling a significant portion of the world’s most valuable digital asset network, Wu Jihan’s journey reflects both the promise and perils of crypto entrepreneurship.
As Bitcoin continues to mature, the balance between decentralization and industrial efficiency will remain a central tension—one shaped increasingly by those who build the tools that power it.
