Introduction
When an adversary builds aircraft carriers, develops nuclear weapons, or establishes overseas military bases, strategists immediately assess implications for national security. These capabilities shift power balances, create vulnerabilities, and demand countermeasures.
Yet when China controlled 65-75% of global Bitcoin hash rate (2017-2021), or when Russia began expanding mining operations using stranded natural gas, strategic communities largely overlooked the implications. This represented a critical blind spot in national security analysis.
Bitcoin mining infrastructure is not just economic activity—it’s cyber-physical strategic capability comparable to traditional military assets. When adversaries control significant hash rate, accumulate Bitcoin reserves, or dominate hardware manufacturing, they gain leverage in emerging digital domains.
This article examines adversary Bitcoin mining implications, analyzes strategic risks, and explores mitigation strategies for nations facing hostile hash rate competition.
Understanding the Threat Landscape
Current Global Hash Rate Distribution
As of 2025, Bitcoin mining is distributed globally with significant concentration:
Major Mining Powers:
- United States: ~37% (post-China ban surge)
- Kazakhstan: ~18% (fossil fuel abundance, proximity to China)
- Russia: ~11% (natural gas resources, sanctions evasion motivation)
- Canada: ~7% (hydroelectric power, cold climate)
- China (illegal/underground): ~5-8% (despite 2021 ban, operations persist)
- Other nations: ~20-25% (distributed globally)

Adversary Definition
For strategic analysis, “adversaries” include:
1. Near-Peer Competitors
- China (strategic rival, technological competitor)
- Russia (geopolitical adversary, cyber aggressor)
2. Regional Threats
- Iran (sanctions target, asymmetric warfare proponent)
- North Korea (nuclear proliferator, cyber-criminal operations)
3. Non-State Actors
- Terrorist organizations (funding mechanisms)
- Criminal cartels (money laundering, sanctions evasion)
- Hostile hacking groups (state-sponsored or independent)
Key Question: What strategic advantages do adversaries gain through Bitcoin mining, and how do these threaten national interests?
Strategic Risks of Adversarial Mining Dominance
Risk 1: Hash Rate Control and Network Manipulation
Threat Scenario: Adversary accumulates >51% global hash rate
Capabilities Enabled:
- Transaction censorship: Block specific transactions or addresses
- Double-spending: Reverse transactions and reuse Bitcoin
- Network forking: Create alternative blockchain versions
- Consensus manipulation: Influence protocol upgrades and governance
Historical Context: China’s 65-75% hash rate dominance (2017-2021) created theoretical attack surface.
Why Attack Wasn’t Executed:
- Economic disincentive: Attack would crash Bitcoin price, destroying Chinese mining revenue
- Hardware losses: Mining equipment becomes worthless after network attack
- Reputation damage: China’s mining industry would lose global credibility
- Detection and response: Global community would detect attack and implement countermeasures
However, in wartime or crisis scenarios, economic incentives change:
- If Bitcoin became critical Western infrastructure, attacking it has strategic value
- Destroying adversary financial capabilities could justify equipment losses
- Wartime logic prioritizes strategic damage over profit
- Pre-positioning hash rate creates attack option when needed
Mitigation Priority: Ensure no single adversary controls >30% hash rate (attack economically prohibitive and technically detectable).

Risk 2: Bitcoin Reserve Accumulation
Threat Scenario: Adversary accumulates massive Bitcoin holdings
Strategic Advantages Gained:
Financial Leverage:
- Large holdings influence market prices (can crash or pump)
- Strategic sales/purchases create economic disruption
- Potential to disrupt Western Bitcoin adoption or reserves
De-Dollarization Tool:
- Bitcoin reserves reduce dependency on dollar-denominated assets
- Alternative settlement layer for sanctioned trade
- Undermines U.S. financial sanctions effectiveness
First-Mover Advantage:
- Early accumulation captures maximum supply at low prices
- Long-term holdings compound in value if Bitcoin adoption grows
- Strategic positioning in emerging monetary system
Example - China:
- Confiscated Bitcoin: 190,000+ BTC seized from PlusToken scam (2019)
- State mining operations (pre-ban): Generated estimated 50,000-100,000 BTC annually
- Strategic reserves: Unknown but likely substantial through various channels
Example - Russia:
- Mining operations: Expanding rapidly (2022-2025) using stranded gas
- Sanctions evasion: Bitcoin provides alternative to SWIFT/Western finance
- Energy monetization: Converts sanctioned energy exports into liquid Bitcoin
Strategic Implication: If Russia and China collectively hold 1-2 million Bitcoin (~5-10% of supply), they gain significant influence over emerging digital reserve asset—potentially shifting monetary system toward multi-polar alternatives.
Risk 3: Mining Hardware Manufacturing Dominance
Current Reality: Chinese companies dominate ASIC manufacturing
Major Manufacturers:
- Bitmain (China): ~60% global market share
- MicroBT (China): ~25% market share
- Canaan (China): ~10% market share
- Western manufacturers: Minimal (<5% combined)
Strategic Vulnerability:
Supply Chain Control:
- Western nations depend on adversary-manufactured hardware
- Potential backdoors or kill switches in mining equipment
- Supply disruptions during geopolitical tensions
- Technology transfer benefits adversary innovation
Export Control Leverage:
- China could restrict ASIC exports to disfavored nations
- Hardware embargoes would cripple Western mining expansion
- Strategic advantage in hash rate competition
Industrial Policy Implications:
- China maintains technological lead in specialized chip design
- Revenue funds further R&D and manufacturing capacity
- Western nations lack domestic alternatives
Mitigation: Develop domestic ASIC manufacturing (U.S., EU, allies) to reduce dependency and ensure supply security.

Risk 4: Energy Weaponization
Threat Scenario: Adversary links Bitcoin mining to energy strategy
Russia Example:
- Stranded gas monetization: Converts flared natural gas into Bitcoin
- Sanctions circumvention: Earns hard currency despite energy export restrictions
- Energy weapon enhancement: Bitcoin mining makes energy sanctions less effective
- Arctic development: Funds remote energy infrastructure via mining revenue
Strategic Problem:
- Western sanctions aimed at limiting Russian energy revenue
- Bitcoin mining provides alternative monetization path
- Effectiveness of energy-based sanctions undermined
- Russia gains strategic flexibility
Iran Example:
- Energy surplus: Significant oil/gas resources, limited export markets (sanctions)
- Mining boom: Government-authorized facilities monetize stranded energy
- Sanctions evasion: Earns foreign currency outside traditional banking system
- Nuclear program funding: Bitcoin mining revenue potentially diverted to strategic programs
Strategic Dilemma: Bitcoin’s censorship resistance makes it impossible to sanction mining operations specifically—adversaries can monetize energy regardless of Western policy.
Risk 5: Asymmetric Warfare Applications
Non-State Actor Threats:
Terrorist Financing:
- Bitcoin enables global fundraising resistant to financial surveillance
- Small mining operations generate untraceable funds
- Difficult to interdict or sanction
- Complements traditional financing methods
North Korea Example:
- State-sponsored hacking: Steals cryptocurrency to fund regime ($3+ billion estimated)
- Mining operations: Suspected small-scale mining using stolen electricity
- Sanctions evasion: Circumvents international financial controls
- Nuclear program funding: Bitcoin sales potentially funding weapons development
Criminal Cartel Applications:
- Money laundering through mining operations (“legitimate” business)
- Ransomware payment demands in Bitcoin
- Tax evasion via unreported mining income
- Cross-border value transfer for illicit trade
Challenge: Bitcoin’s pseudonymity and censorship resistance make it attractive for illicit actors, though blockchain transparency enables some law enforcement tracing.
Case Study: China’s Mining Dominance (2017-2021)
Historical Context
From Bitcoin’s early years through 2021, China dominated global mining:
Peak Dominance (2019-2020):
- Hash rate share: 65-75% of global total
- Mining pools: Top pools (F2Pool, BTC.com, Antpool) China-based
- Hardware manufacturing: 80%+ global ASIC production
- Electricity advantage: Cheap coal power in Inner Mongolia, Xinjiang; hydro in Sichuan
Strategic Risks Realized
Concentration Vulnerability:
- Single government potentially controlled majority hash rate
- Regulatory changes could instantly shift network security
- Geographic concentration created infrastructure risk (natural disasters, grid failures)
Censorship Capability (theoretical):
- Chinese government could have ordered mining pools to censor transactions
- Specific addresses or transaction types could be blocked
- Western financial activity potentially disrupted
Supply Chain Control:
- ASIC export restrictions could have crippled Western mining
- Hardware backdoors potential (though no evidence found)
- Technology lead in specialized chip manufacturing
China’s 2021 Mining Ban
Events:
- May-June 2021: Chinese government banned Bitcoin mining nationwide
- Rationale: Energy consumption, financial risk, capital flight concerns
- Result: Estimated 50-60% hash rate drop within weeks
- Migration: Miners relocated to U.S., Kazakhstan, Russia, Canada
Immediate Impacts:
- Bitcoin network continued functioning despite massive hash rate loss (resilience demonstrated)
- Mining difficulty adjusted downward, maintaining 10-minute block times
- Geographic distribution massively improved
- U.S. emerged as largest mining nation (~37% hash rate)
Strategic Lessons:
For Bitcoin Network:
- ✅ Resilience validated: 50%+ hash rate loss didn’t destroy network
- ✅ Decentralization works: Network self-corrected through difficulty adjustment
- ✅ Migration speed: Miners relocated equipment within months (faster than expected)
For China:
- ❌ Voluntary strategic retreat: Ceded cyber-territorial control to competitors
- ❌ Economic loss: $10+ billion annual mining revenue transferred to other nations
- ❌ Technology exodus: Mining expertise fled to rivals
- ⚠️ Possible strategic reconsideration: Underground mining reportedly continues; policy may reverse
For Western Nations:
- ✅ Windfall opportunity: U.S. captured largest hash rate share
- ✅ Reduced adversary threat: Chinese dominance eliminated
- ⚠️ Temporary advantage: China could reverse policy, Russia expanding rapidly
Key Insight: China’s ban represented voluntary surrender of cyber-physical strategic capability—analogous to decommissioning aircraft carriers or closing military bases. Whether this proves wise long-term remains uncertain.

Current Adversary Strategies (2025)
Russia: Aggressive Expansion
Approach:
- Legalize and regulate Bitcoin mining (2022)
- Leverage stranded natural gas from oil fields (flare gas monetization)
- Target 10-15% global hash rate within 5 years
- Integrate mining with sanctions evasion strategy
Strategic Objectives:
- Earn hard currency despite energy sanctions
- Build Bitcoin reserves outside Western financial system
- Develop cyber-physical strategic capability
- Reduce dollar dependency
Implications for West:
- Russia gaining significant hash rate share (~11% and growing)
- Bitcoin becoming sanctions-evasion tool
- Energy sanctions effectiveness undermined
- Strategic competition in cyber-physical domain
China: Underground Continuation + Strategic Reassessment
Current Status:
- Official ban remains (as of 2025)
- Underground mining estimated at 5-8% global hash rate
- Hardware manufacturing dominance continues (~80% global)
- Strategic Bitcoin reserves likely maintained (confiscated coins + early mining)
Possible Future Scenarios:
Scenario 1: Ban Continues
- Underground operations persist at small scale
- Manufacturing dominance provides indirect influence
- Strategic reserves held but not increased significantly
- Bitcoin seen as threat to capital controls and digital yuan
Scenario 2: Policy Reversal
- China recognizes strategic error and re-legalizes mining
- Rapid hash rate recapture (infrastructure still exists)
- Global distribution shifts back toward China
- Western advantage short-lived
Scenario 3: Hybrid Approach
- State-controlled mining allowed (private mining banned)
- Government accumulates Bitcoin through official operations
- Combines control with strategic positioning
- Maximizes leverage while managing risks
Wild Card: China’s digital yuan (CBDC) strategy may conflict with Bitcoin adoption, making reversal politically complex.
Iran: Sanctions Evasion Focus
Strategy:
- Government-licensed mining to monetize energy
- Bitcoin sales fund imports and circumvent sanctions
- Small but growing hash rate share (~2-3%)
Limitations:
- Energy infrastructure challenges (aging grid, sanctions impact)
- Limited access to latest mining hardware
- Smaller scale than Russia or historical China
Implications:
- Bitcoin demonstrates sanctions resistance
- Provides model for other sanctioned nations
- Complicates Western economic pressure strategies
North Korea: Cyber-Criminal Hybrid
Approach:
- Hacking and theft primary method (minimal actual mining)
- Targets cryptocurrency exchanges and infrastructure
- Estimated $3+ billion stolen 2016-2023
- Funds nuclear/missile programs
Unique Threat:
- Asymmetric approach (theft vs. infrastructure investment)
- State-sponsored cybercrime at massive scale
- Bitcoin serves as both target and tool
Countermeasures:
- Enhanced exchange security
- Blockchain analysis and tracking
- International cooperation on crypto-crime
- Sanctions on Bitcoin addresses (limited effectiveness)
Mitigation Strategies
Strategic Imperative 1: Build Domestic Hash Rate
Objective: Ensure allied nations collectively control >60% global hash rate
Approach:
- U.S., EU, Canada, Australia, Japan coordinate mining expansion
- Target: 10-15% hash rate per major ally (combined 60%+)
- Prevents any single adversary achieving dominance
- Creates resilient, distributed security
Implementation: See Bitcoin defense budgets framework and mining infrastructure guide.
Strategic Imperative 2: Develop Domestic ASIC Manufacturing
Objective: Break Chinese hardware monopoly
Approach:
- Government support for domestic chip fabrication (subsidies, R&D funding)
- Military procurement preferences for allied-manufactured ASICs
- Technology transfer restrictions on adversary hardware (security screening)
- Build redundant supply chains across allied nations
Rationale: Hardware independence essential for long-term hash rate competition
Strategic Imperative 3: Accumulate Strategic Bitcoin Reserves
Objective: Prevent adversary reserve dominance
Approach:
- Strategic reserve acquisition by U.S., EU, allied nations
- Target: Allied nations collectively hold >20% total supply
- Counters adversary holdings and maintains balance
- Provides optionality in emerging monetary system
Urgency: Early accumulation maximizes strategic positioning
Strategic Imperative 4: Enhance Sanctions Effectiveness
Challenge: Bitcoin undermines financial sanctions
Adaptations:
- Focus on physical infrastructure (mining hardware, energy input) not Bitcoin itself
- Secondary sanctions on entities supporting adversary mining
- Blockchain analysis to track and potentially seize illicit proceeds
- Accept Bitcoin’s censorship resistance as reality, work within constraints
Realism: Complete sanctions on Bitcoin use impossible; focus on limiting adversary advantages rather than total interdiction.
Strategic Imperative 5: International Coordination
Approach:
- Allied mining cooperation (NATO, Five Eyes, plus Japan, South Korea, Australia)
- Coordinated hash rate expansion targets
- Shared threat intelligence on adversary mining activities
- Technology and best practice sharing
Benefit: Collective security approach distributes costs, maximizes resilience, prevents fragmentation.
Conclusion
Adversarial Bitcoin mining is not theoretical—it’s actively happening. Russia expands hash rate to evade sanctions. China maintains underground operations and manufacturing dominance. Iran funds government operations through mining. North Korea steals billions via crypto-hacking.
These activities create genuine strategic risks:
- Hash rate concentration enabling network attacks
- Bitcoin reserve accumulation shifting monetary balance
- Hardware monopolies creating supply chain vulnerabilities
- Energy weaponization undermining sanctions effectiveness
- Asymmetric warfare applications funding hostile actors
The strategic imperative is clear: Allied nations must treat Bitcoin mining as critical national security infrastructure, build domestic capabilities, and prevent adversarial dominance.
Inaction cedes cyber-physical strategic advantage to competitors. Early, decisive action secures position in emerging digital order.
The question is not whether adversary mining matters—it demonstrably does. The question is whether democratic nations will respond with commensurate urgency and investment.
