The Hong Kong summer of August was sweltering in 2018, but the atmosphere at the Ritz-Carlton felt anything but warm. Wu Jihan, co-founder of Bitmain, stood on stage supporting Bitcoin Cash (BCH) on its first anniversary — a symbolic gesture during a time when the cryptocurrency market had already entered a deep freeze. After a final surge at the beginning of the year, digital assets had been in steady decline for six months. By August 20, Bitcoin traded at $6,402, down 67.4% from its January peak of $19,664. Meanwhile, BCH — backed heavily by Bitmain — had plummeted 78.5% from its all-time high of $4,095 to just $880.96.
The crypto market’s volatility was on full display: fortunes built in months could vanish just as quickly. For Bitmain, a company founded in 2013, this moment marked both a peak and a turning point. Having reportedly secured a $300–400 million Series B round in July 2018 at a $12 billion valuation, the firm stood as one of the most valuable private tech startups globally — a true unicorn alongside giants like Uber and Airbnb.
A Meteoric Ascent
Bitmain’s success stemmed from its dominance in ASIC mining hardware. Through its Antminer series, the company revolutionized cryptocurrency mining, rendering CPU and GPU-based operations obsolete. By 2018, Bitmain controlled over 70% of the global market for mining equipment, with矿机 sales accounting for more than 90% of its revenue.

Its financials were staggering. In Q1 2018 alone, Bitmain reported $1.14 billion in net profit — nearly matching its full-year 2017 earnings of $1.25 billion. This explosive growth fueled rumors of an IPO in Hong Kong, a move that would have capitalized on investor enthusiasm before the bear market deepened.
But such rapid success inevitably drew scrutiny.
The “Mining Tyrant” Controversy
In mining communities, whispers persisted that Bitmain pre-ran its own Antminer devices in its Antpool before selling them to customers. Some buyers reported receiving units with dust inside or unstable hash rates — signs of prior use. While unconfirmed, the practice — if true — gave Bitmain an unfair advantage: deploying new hardware during low-difficulty periods to maximize early returns.
Even without proof, Bitmain’s market power was undeniable. The company dictated supply rhythms, sometimes releasing batches months apart, other times flooding the market within weeks. This unpredictability directly impacted miner profitability.
Consider the case of the Litecoin L3 miner: launched at 10,000 yuan ($1,450), its price dropped to 6,200 yuan before delivery and crashed to 3,200 yuan within two months. Such volatility left miners reeling — and accusing Bitmain of predatory dumping.
This control earned Bitmain the nickname “the mining tyrant.” Critics argued that decentralization — the foundational ideal of blockchain — was being undermined by a single centralized force capable of influencing network security and coin distribution.
Centralization vs. Decentralization: A Broken Promise?
In 2010, anyone with a laptop could mine Bitcoin. Mining was democratic, accessible, and aligned with Satoshi Nakamoto’s vision. But Bitmain’s ASIC dominance turned mining into an industrial-scale operation, accessible only to those who could afford massive farms and cheap electricity.
With control over an estimated 10–20% of global mining power, Bitmain wielded significant influence over blockchain networks. When Bitcoin Gold (BTG) suffered a 51% double-spend attack in 2018, the community pointed fingers at Bitmain, suspecting it had used its hash power to manipulate the network. Wu Jihan dismissed the claim on Twitter, calling BTG “not worth attacking,” but the damage to trust was done.
Other projects responded by hard-forking to resist ASIC miners. Monero (XMR), for example, updated its algorithm to block ASICs, leading to a community split and multiple forks — XMC, PZ, XMO, and XMZ — fragmenting developer efforts and user bases.

The irony was clear: a technology built to eliminate central authorities had birthed its own oligarchs.
Diversification in the Downturn
As the bear market intensified, even giants felt the pressure. NVIDIA, once a key beneficiary of crypto mining demand, reported only $18 million in crypto-related revenue in Q2 2018 — a fraction of previous quarters. CEO Jensen Huang stated that cryptocurrency’s impact on future earnings would be “immaterial.”
Bitmain knew it couldn’t rely solely on mining hardware forever.
In November 2017, it launched Sophon BM1680, an AI acceleration chip designed for deep learning and edge computing. Wu Jihan publicly stated that AI could account for up to 40% of Bitmain’s revenue within five years.
Beyond hardware, Bitmain expanded into blockchain investments. It backed mining pool ViaBTC, AI-chain project AICHAIN, and blockchain initiatives under gaming companies like Hero Entertainment and Kingnet. These moves signaled a strategic pivot — from pure hardware play to a broader tech ecosystem player.
Can Bitmain Reinvent Itself?
The question remains: can a company so deeply tied to the crypto cycle survive its downturns?
Bitmain’s core strengths — semiconductor design, supply chain mastery, and energy-efficient computing — are transferable to AI, IoT, and high-performance computing markets. But transitioning from a niche crypto hardware leader to a diversified tech innovator is no small feat.
Internal challenges also loomed. Reports of leadership disputes between Wu Jihan and fellow co-founder Micree Zhan surfaced in late 2018, culminating in public power struggles that weakened corporate stability.

Yet despite setbacks, Bitmain’s legacy endures. It shaped the modern mining landscape, accelerated blockchain infrastructure development, and proved that Chinese tech startups could dominate global crypto markets.
Frequently Asked Questions (FAQ)
Q: What is Bitmain known for?
A: Bitmain is best known for manufacturing ASIC-based cryptocurrency miners, particularly its Antminer series, which dominate global mining hardware sales.
Q: Is Bitmain still profitable?
A: While exact figures vary post-2018, Bitmain remained profitable during the bull runs of 2017 and early 2018. However, prolonged bear markets and internal issues impacted long-term financial stability.
Q: Did Bitmain go public?
A: Despite filing for a Hong Kong IPO in 2018, Bitmain did not successfully list. Multiple attempts followed in later years amid regulatory scrutiny and market conditions.
Q: What is the Sophon BM1680?
A: The Sophon BM1680 is an AI inference chip developed by Bitmain for applications in machine learning, video analytics, and smart edge devices.
Q: Why did Monero fork away from ASIC miners?
A: Monero developers believed ASIC dominance threatened network decentralization. By modifying their hashing algorithm (CryptoNight), they aimed to preserve fairness for CPU and GPU miners.
Q: What happened to Bitcoin Cash after Bitmain's support?
A: Despite strong backing from Bitmain, Bitcoin Cash faced ongoing controversy over scalability and centralization. It remains a notable but contentious fork of Bitcoin.
