Kazakhstan’s journey in the world of Bitcoin mining is a compelling story of rapid growth, unexpected collapse, and uncertain rebirth. Once the second-largest Bitcoin mining hub globally, the country now faces structural constraints, regulatory tightening, and energy instability. This article explores the rise and fall of Kazakhstan’s mining industry, analyzes the impact of new regulations, and highlights key lessons for miners worldwide.
The Meteoric Rise and Sharp Decline of Kazakhstan’s Mining Sector
In 2021, Kazakhstan surged to become the world’s second-largest Bitcoin mining nation, capturing up to 18% of global hashrate by October. Mining capacity exploded from 500 MW in January to a peak of 1,500 MW by year-end. This boom was fueled by four key factors:
- Abundant, cheap electricity: Government-imposed price caps kept electricity between $0.02–$0.03 per kWh—highly competitive globally.
- Capital inflow from Western miners: Investors from the U.S. and Europe sought affordable, secure locations for deploying ASICs during the bull market.
- China’s mining ban (May 2021): The exodus of Chinese mining rigs redirected thousands of machines to neighboring Kazakhstan.
- Favorable IT regulations and tax incentives: The government promoted tech diversification, allowing miners to register as IT firms and benefit from tax breaks.

However, this rapid expansion soon overwhelmed the country’s aging Soviet-era power grid. Unlike modern systems with demand-response mechanisms (like Texas), Kazakhstan lacked the infrastructure to dynamically manage sudden spikes in electricity demand. Rolling blackouts began in summer 2021, especially in the energy-strapped southern regions.
By September 2021, the national grid operator KEGOC started restricting power to miners. What followed was a cascade of crises: electricity rationing, reliance on expensive imported power from Russia ($0.07–$0.09/kWh), and widespread operational shutdowns. By May 2023, Kazakhstan’s hashrate share had plummeted to just 4%, with active capacity down to around 400 MW.
Energy Infrastructure: Coal-Powered but Struggling
Kazakhstan is an energy superpower, rich in oil, gas, coal, and uranium. Yet its geography—a landlocked nation thousands of kilometers from seaports—limits export potential, especially for low-value-density coal.
As of 2021:
- 68% of electricity came from coal
- 20% from natural gas
- 8% from hydropower
- 4% from wind and solar
Most coal plants were built during the Soviet era and now suffer from decades of underinvestment. While new coal facilities are being constructed, the government aims to boost renewables, particularly wind and solar, which thrive in the country’s vast steppes.
Despite being the world’s top uranium producer, Kazakhstan has no nuclear power—though plans exist for a 2.4 GW nuclear plant by 2035. For now, coal remains the backbone of baseload power.
Mining clusters are concentrated in industrial hubs like Karaganda, Pavlodar, Ekibastuz, and Oskemen—areas with existing power generation and transmission infrastructure. Some western regions near Caspian oil fields also host mining operations using associated gas (a byproduct of oil extraction) for off-grid power.
New Regulations: Stability at a Cost
After over a year of regulatory uncertainty, Kazakhstan enacted the Digital Assets Law on April 1, 2023. Rather than banning mining, the government opted for strict oversight—a common approach for strategic industries.
The law impacts miners in four major ways:
1. Licensing Requirements for Miners and Service Providers
All miners must obtain government licenses. Additionally:
- Only licensed mining pools can operate
- Miners must sell Bitcoin through approved local exchanges
- All entities must register with the Astana International Financial Center (AIFC)
Currently, seven exchanges are licensed, including Binance (a close government partner). The local sales mandate increases gradually:
- 25% in 2023
- 50% in 2024
- 75% in 2025
This ensures tax compliance and keeps capital within the domestic economy.
2. Miners Are Last in Line for Power
Under the new rules, miners can no longer buy electricity like regular businesses. Instead, they must use the KOREM auction system, where only “excess” grid power is offered—allocated at KEGOC’s discretion.
This creates uncertainty:
- No guarantee of sufficient supply
- Auction prices may spike during shortages
- Miners risk shutdowns during peak demand
Alternative options include:
- Importing power from Russia – too expensive ($0.07–$0.09/kWh)
- Direct contracts with energy producers – currently the most viable path

3. A Tiered Electricity Tax System
The government introduced a complex tax structure designed to set a de facto price floor:
| Power Source | Tax Rate | Effective Floor Price |
|---|---|---|
| Grid (via KOREM) or Russian imports | +20 tenge/kWh (~$0.045) | $0.055/kWh |
| Off-grid (fossil fuels) | Flat 10 tenge/kWh (~$0.022) | ~$0.052/kWh |
| Renewable (wind/solar) | Only 1 tenge/kWh (~$0.0022) | ~$0.032/kWh |
The $0.055/kWh floor is telling—it aligns closely with the break-even cost for mid-efficiency miners during bear markets. This suggests the tax is less about efficiency and more about revenue extraction.
While off-grid fossil fuel arrangements remain possible, taxes erode their cost advantage. The best hope lies in developing renewable or associated gas projects, though current renewable capacity (4%) is insufficient.
Operational Realities: Climate and Labor
Despite regulatory hurdles, Kazakhstan offers solid operational conditions:
- Climate: Northern mining hubs experience temperatures from -15°C (6°F) in winter to 21°C (70°F) in summer—ideal for passive cooling.
- Most facilities use evaporative cooling in summer; cold winters reduce cooling needs but require airflow adjustments.
- Compared to Texas or Iceland, Kazakhstan offers a balanced thermal environment.
- Labor: A young, tech-savvy workforce with low labor costs makes staffing mines relatively easy and affordable.
The Road Ahead: Uncertain but Not Hopeless
The future of Bitcoin mining in Kazakhstan hinges on two factors: energy independence and regulatory clarity.
For long-term viability, miners must develop their own power sources:
- Associated gas projects near oil fields offer low-cost, off-grid solutions
- Building private wind and solar farms could unlock tax advantages
- Coal-based captive power remains possible but faces political and environmental scrutiny
However, foreign investment remains cautious. After the chaos of 2021–2023 and Russia’s more favorable mining conditions just across the border, many international players are hesitant to return.
Key Lessons for Global Miners
Kazakhstan’s experience offers two critical takeaways:
1. Political Risk Is Always Present
In early 2021, Kazakhstan was seen as safe and miner-friendly. Yet within months, blackouts and regulatory crackdowns disrupted operations. Similar risks exist in other emerging markets like Paraguay or Argentina—today’s haven could be tomorrow’s trap.
2. Avoid Subsidized or Price-Capped Electricity
Relying on artificially cheap power—especially in fragile grids—invites regulatory backlash. Countries like Kyrgyzstan have already cracked down on miners exploiting subsidized rates. The safest strategy? Operate off-grid, with transparent, market-based energy contracts.
Frequently Asked Questions (FAQ)
Q: Why did Kazakhstan’s Bitcoin hashrate drop so sharply?
A: The rapid influx of mining rigs overwhelmed an outdated power grid, leading to blackouts and forced rationing. Regulatory uncertainty and high taxes further reduced profitability.
Q: Can miners still profit under the new tax rules?
A: Profitability is limited under grid-based models due to the $0.055/kWh effective price floor. Off-grid operations using associated gas or renewables offer better margins.
Q: Is it safe to invest in Bitcoin mining in Kazakhstan now?
A: With new regulations providing clarity, some stability has returned. However, political and energy risks remain high compared to jurisdictions with stronger institutions.
Q: What energy sources are most viable for future mining projects?
A: Associated natural gas (a byproduct of oil drilling) and privately developed wind/solar farms offer the best long-term potential due to lower costs and tax benefits.
Q: How does Kazakhstan compare to Texas as a mining location?
A: Texas offers superior grid flexibility (demand-response programs), lower political risk, and more transparent regulation. Kazakhstan’s advantage lies in lower labor costs and proximity to Central Asian energy resources—but comes with greater volatility.
Q: Will Kazakhstan ever regain its former mining dominance?
A: A return to 18% global share is unlikely without massive investment in energy infrastructure and deregulation. However, it can remain a significant regional player if miners adopt off-grid solutions.
