The cryptocurrency mining landscape may be entering a pivotal phase, as industry giant Bitmain prepares to deploy approximately 200,000 mining rigs across hydro-rich regions in southwestern China. This strategic move signals a potential resurgence in mining activity and hints at shifting market dynamics amid improving profitability and seasonal energy advantages.
Strategic Deployment Ahead of the Wet Season
Insiders from mining farm operators in China’s Sichuan and Yunnan provinces reveal that Bitmain has already begun securing agreements to install its mining hardware ahead of the annual rainy season, which typically begins in May. By positioning equipment in advance, Bitmain aims to capitalize on low-cost hydropower during the summer months when excess energy generation drives electricity prices down.
Reports indicate that the deployment will include a mix of newer models like the AntMiner S11 and S15, along with older units such as the AntMiner S9i/j. Notably, these latest models are currently listed as “sold out” on Bitmain’s official store, suggesting strong demand or a deliberate inventory shift toward self-operated mining operations.
While Bitmain has historically focused on mining hardware sales rather than direct mining, the current market conditions make internal mining increasingly attractive. With electricity costs in the region estimated at just **$0.037 per kWh** during peak hydropower output—below the industry benchmark of $0.05—the profit margins for large-scale mining improve significantly.

Profitability Gains Drive Internal Mining Appeal
According to f2pool, one of the world’s top three mining pools, mining profitability has rebounded under current market conditions. Using Bitcoin’s present price and a base electricity rate of $0.05/kWh:
- AntMiner S9j: ~$0.87/day
- AntMiner S11: ~$1.80/day
- AntMiner S15: ~$2.88/day
When adjusted for the lower regional rate of $0.037/kWh, daily profits increase to:
- S9j: $1.29
- S11: $2.24
- S15: $3.38**
Even if all 200,000 units were lower-end S9j miners, this scale of operation could generate roughly $7.7 million per month in revenue. This makes internal mining not only viable but potentially more lucrative than selling off inventory—especially in a sluggish secondary market.
Has the Mining Market Bottomed Out?
The expansion comes after a prolonged bear market that forced over 600,000 Bitcoin miners offline in 2018, many selling older rigs like the S9 at steep discounts. During that downturn, Bitmain itself scaled back its mining operations.
Historical data shows that in October 2018, Bitmain reported a hash rate of about 2,339 quadrillion hashes/s across its SHA-256-based mining fleet. Assuming use of AntMiner S9 units (each producing ~14 terahashes/s), this equated to roughly 170,000 active machines.
By March 2019, that figure dropped to 1,692 quadrillion hashes/s, implying a reduction of around 50,000 units—a clear sign of contraction during the crypto winter.
Now, signs point to recovery. If Bitmain deploys 200,000 AntMiner S11 units—each capable of delivering 19.5 terahashes/s—the company could add approximately 3,800 quadrillion hashes/s (or 3.8 exahashes/s) to the network.
Given that Bitcoin’s current network hash rate stands around 48,000 quadrillion hashes/s, this would give Bitmain control over roughly 7.9% of total network hashrate—a significant share that could influence mining pool dynamics and decentralization debates.
Some analysts predict total network hashrate could climb to 70 exahashes/s during the upcoming wet season, surpassing previous highs of 60 exahashes/s, driven by renewed activity from Bitmain and other large-scale miners returning to low-cost regions.
A Shift in Business Model and Revenue Streams
Bitmain’s business model has evolved significantly over the years. While mining hardware sales have always been core, internal mining once played a larger role.
Financial disclosures from Bitmain’s 2018 Hong Kong IPO filing show:
- Self-mining revenue dropped from 20.3% of total income in 2015 to just 7.9% in 2017
- By the first half of 2018, it had fallen further to 3.3%
- Conversely, miner sales revenue rose from 78.6% to 94.3% in the same period
This shift underscores growing reliance on equipment sales—but also exposes the company to market volatility. Unconfirmed reports suggest Bitmain suffered a $500 million net loss in Q3 2018, largely due to falling crypto prices and oversupply in the miner market.
Despite this, Bitmain maintained strategic reserves: as of June 30, 2018, it operated 11 mining farms across Sichuan, Xinjiang, and Inner Mongolia, and held stockpiles of around 200,000 mining machines—many now likely being redeployed.
These facilities serve dual purposes: some support Bitmain’s own mining operations, while others offer mining hosting services to third parties—an increasingly important revenue stream amid fluctuating hardware demand.

Frequently Asked Questions (FAQ)
Q: Why is Bitmain deploying miners now instead of selling them?
A: With electricity costs dropping during China’s summer wet season and Bitcoin prices stabilizing, internal mining has become more profitable than selling older models in a weak secondary market.
Q: How much electricity do these miners consume?
A: The AntMiner S9j uses about 1,350 watts, S11 around 1,450 watts, and S15 roughly 1,650 watts. Efficiency improves with newer models, making them better suited for sustained operations.
Q: Could this affect Bitcoin’s decentralization?
A: A single entity controlling nearly 8% of the network hash rate raises concerns about centralization risks, especially if combined with dominance in mining pool operations.
Q: Is Bitmain still profitable after 2018 losses?
A: While official 2019 figures aren’t public, renewed mining activity and improved market conditions suggest a recovery path, particularly through diversified revenue like hosting services.
Q: Will this lead to higher Bitcoin transaction fees?
A: Increased hash rate typically strengthens network security but doesn’t directly raise fees unless block space demand increases. However, more competition among miners can stabilize fee markets.
Q: Are other companies following Bitmain’s lead?
A: Yes—many mid-sized miners are relocating or expanding into hydropower zones in Southwest China and Central Asia to replicate similar cost advantages.
Conclusion: A Calculated Re-Entry into Mining
Bitmain’s move to activate 200,000 miners ahead of the wet season reflects a calculated bet on market recovery and energy arbitrage. It marks a shift from pure hardware vendor to active participant in the mining ecosystem—leveraging geography, timing, and scale to regain profitability.
As global interest in sustainable mining grows and energy efficiency becomes paramount, Bitmain’s strategy may set a precedent for how major players adapt to cyclical markets.
