Bitcoin has plummeted to levels not seen since early 2017, dropping below $4,300 and erasing nearly 78% of its value from the 52-week high near $20,000. This sharp decline has reignited concerns across the cryptocurrency market, with analysts pointing to a confluence of macroeconomic sentiment and internal network conflicts—particularly the Bitcoin Cash (BCH) hard fork—as key triggers. At the center of the storm stands Bitmain, the dominant mining hardware manufacturer, whose strategic moves in the BCH ecosystem have drawn intense scrutiny.
The Price Plunge: From Euphoria to Correction
Bitcoin’s meteoric rise in 2017 saw prices surge nearly 20-fold, climbing from around $1,000 at the start of the year to an all-time peak above $19,500 by December. However, the subsequent bear market has been equally dramatic. After months of trading above the $6,000 mining cost threshold, Bitcoin broke below that critical support in mid-November and continued its descent.
According to CoinMarketCap’s weighted pricing data, Bitcoin has since stabilized around $4,450—a level comparable to prices seen in September 2017, when Chinese regulators cracked down on initial coin offerings (ICOs). This full-circle moment underscores the volatility inherent in digital assets and raises questions about long-term sustainability amid weakening investor confidence.

Bitcoin Cash Hard Fork: Catalyst for Chaos
While broader market sentiment has been bearish throughout 2018, the immediate catalyst for the latest downturn appears tied to the contentious hard fork of Bitcoin Cash. The split pitted two factions against each other: one led by Bitmain and its affiliated Bitcoin ABC development team, and another backed by Craig Wright and nChain advocating for larger block sizes.
The dispute centered on technical governance—specifically, whether to implement Canonical Transaction Ordering (CTOR) and new opcodes (Bitcoin ABC’s proposal), or pursue further block size increases (nChain’s vision). What began as a philosophical debate escalated into a "hash rate war," where both sides mobilized mining power to assert dominance over the BCH network.
This conflict introduced significant uncertainty into the market. As blockchain analyst Whalepanda noted, such infighting erodes consensus—the foundational principle of decentralized networks—and can trigger panic selling. Bloomberg strategist Mike McGlone went further, predicting Bitcoin could fall another 70%, potentially bottoming out near $1,500 if institutional confidence continues to wane.
Bitmain’s Central Role and Strategic Risks
Bitmain is no neutral observer in this drama. As the co-creator of Bitcoin Cash and a major holder—reportedly owning over 1 million BCH—the company had both ideological and financial stakes in the outcome. Its support for Bitcoin ABC was decisive, and following the fork, Wenceslas Wu (Wu Jihan), Bitmain’s co-founder, publicly celebrated the victory.
However, hash rate wars are costly. Since both Bitcoin and Bitcoin Cash use the same SHA-256 mining algorithm, miners must choose where to allocate their computing power. With profitability diverging between chains, Bitmain was forced to redirect substantial resources toward supporting Bitcoin ABC—effectively burning capital to maintain influence.
This strategic gamble has real financial consequences:
- BCH’s price collapsed from over $600 in early November to around $230 post-fork.
- Bitmain’s revenue model remains heavily reliant on mining hardware sales (94.3% of total income).
- Fluctuations in cryptocurrency prices directly affect its balance sheet; as of June 30, 2018, digital asset impairments totaled $103 million.
Moreover, Bitmain’s own operational cash flow was negative—$622 million—for the first half of 2018. While the company attributes this to receiving $750 million in crypto payments not reflected in traditional cash flow metrics, it highlights a fundamental vulnerability: when coin prices fall, so does perceived value and liquidity.
Business Model Under Pressure
Beyond the fork drama, structural challenges threaten Bitmain’s dominance:
- Stagnant Innovation: For years, Bitmain’s Antminer S9 has been its flagship product. Despite launching newer models like the V9, sales have disappointed. First-quarter 2018 inventory reached $1.2 billion, including unsold V9 units.
- Talent Drain: Key chip designers, including Yang Zuoxing—who led development of the S7 and S9—have left to found competitors like MicroBT (maker of WhatsMiner), intensifying competition.
- Rising R&D Costs: Production expenses soared from $93.7 million in 2017 to $1.5 billion in the first half of 2018 as Bitmain invested heavily in 7nm chip technology and AI chips.
- Diversification Struggles: Though Bitmain aims to expand into AI, less than 1% of revenue comes from non-mining sources. Its 7nm Antminer S15 (28TH/s, 57J/T efficiency) launched in November, but rivals like Canaan Creative (AvalonMiner), GMO, and AMD are closing the gap.
Bitmain also operates major mining pools—BTC.COM and Antpool—and once derived over 20% of revenue from self-mining. That figure has now dropped to just 3.3%, reflecting declining margins in a saturated market.

Leadership Shakeup and IPO Speculation
In parallel with technical and financial pressures, Bitmain has undergone internal restructuring. Board changes removed赵肇丰 (Zhao Zhaofeng), 葛越晟 (Ge Yuosheng), and 周锋 (Zhou Feng) as directors, while Hu Yishuo stepped down as监事 (supervisor). The new structure positions co-founders Jiang Zhuoer (36% stake) and Wu Jihan (20.25%) as controlling shareholders through weighted voting rights.
Despite rumors of an impending Hong Kong IPO—fueled by a temporary ticker code "90027" appearing on Tiger Brokers—Bitmain has remained silent. If pursued, going public would subject the firm to greater transparency demands at a time when profitability is under pressure and market sentiment is fragile.

Frequently Asked Questions (FAQ)
Q: Why did Bitcoin drop so sharply in late 2018?
A: A combination of factors contributed: weakening investor sentiment after the 2017 bubble burst, declining institutional interest, and the destabilizing effect of the Bitcoin Cash hard fork—a conflict in which Bitmain played a central role.
Q: What is a hash rate war?
A: It occurs when competing factions in a blockchain network direct large amounts of mining power (hash rate) toward different versions of a chain during a hard fork. The goal is to prove economic support and ensure one chain survives while the other fails.
Q: How does Bitmain profit from mining?
A: Primarily through selling ASIC mining hardware like Antminers. It also earns revenue from operating mining pools and self-mining operations, though these contribute less than before.
Q: Is Bitmain still dominant in mining hardware?
A: While still a major player, its lead is narrowing. Competitors like MicroBT and Canaan are gaining ground with advanced chip designs, and Bitmain’s failure to innovate beyond the S9 series has hurt its reputation.
Q: Could Bitcoin really fall to $1,500?
A: Some analysts like Mike McGlone believe so under prolonged bear conditions. However, many see strong support around $3,500–$4,000 due to long-term holders ("HODLers") and fundamental network value.
Q: What happens if Bitmain fails?
A: A collapse would disrupt mining hardware supply and pool infrastructure but wouldn’t break Bitcoin itself. Decentralization ensures no single entity controls the network—even one as influential as Bitmain.
