The world of cryptocurrency began with a single block — the genesis block mined by Satoshi Nakamoto in 2009. Since then, crypto mining has evolved from a niche hobby into a global industrial operation spanning over 114 countries. What started as a decentralized dream is now powered by massive mining farms consuming vast amounts of energy and generating billions in annual revenue. According to blockchain analytics, miners earned approximately $4.1 billion in the past year — not including profits from hardware sales, which alone may reach $3–4 billion annually.
As Bitcoin continues its digital gold rush, the infrastructure behind it grows more sophisticated. The network’s mining difficulty increases over time, ensuring that even though 80% of Bitcoin has already been mined, the final coins won’t be released until around 2140. This rising complexity demands more computational power — and more electricity. In fact, Bitcoin mining consumes an estimated amount of energy equivalent to 30 nuclear reactors running at full capacity. Energy costs alone eat up 30–60% of mining profits, making location and efficiency critical.
Despite the halving of block rewards — now down to 6.25 BTC per block — miners still earn substantial income through transaction fees, sometimes exceeding $20 million per day collectively. This profitability fuels innovation and expansion, pushing companies to build ever-larger facilities in optimal locations.
The Evolution of Mining Hardware
In the early days, anyone could mine Bitcoin using a standard desktop computer. But as competition grew, so did the need for specialized equipment. By 2017, demand for graphics processing units (GPUs) surged as miners sought powerful yet accessible hardware. Over three million discrete GPUs were sold that year for more than $776 million, creating shortages that left gamers scrambling for components.
Manufacturers like AMD and Nvidia saw explosive growth: Nvidia’s revenue jumped over 50% year-on-year in Q2 2017, while AMD reported $1.2 billion in revenue. However, as the market cooled in 2018, both companies anticipated declines in mining-related sales.
Today, mining is no longer about consumer-grade parts. It's an industrial-scale operation. Massive mining farms house thousands of ASIC (Application-Specific Integrated Circuit) miners — machines built solely for cryptocurrency mining. These farms are often housed in repurposed factories or remote data centers where low electricity costs and natural cooling provide a competitive edge.
One notable example is CoinMint, which plans to invest $700 million into transforming a former aluminum smelter in upstate New York into a high-efficiency Bitcoin mine. The project aims to create 150 jobs and leverage affordable hydropower from nearby dams.

1. GigaWatt – Washington, USA
- Founded: 2012
- Location: Washington State, USA
- Hashrate: 1.3 PH/s
Dave Carlson, a former software developer turned entrepreneur, launched GigaWatt from his basement during financial hardship. What began as a small operation quickly scaled into North America’s largest mining farm.
Now based in a converted industrial warehouse (exact location undisclosed for security), GigaWatt runs on one of the cheapest power grids in the U.S. Washington offers commercial electricity at just $0.0842 per kWh, giving the farm a significant cost advantage.
With monthly operating costs exceeding $1 million — covering salaries for 15 employees and massive energy consumption — GigaWatt remains profitable thanks to its efficient infrastructure and strategic location. Carlson also ventured into hardware production, manufacturing ASIC miners using Bitfury chips for global distribution.
2. Genesis Mining – Iceland
- Founded: 2014
- Primary Locations: Iceland, Canada
- Hashrate: 1,000 GH/s
Genesis Mining operates some of the most geographically strategic farms in the world. By placing facilities in Iceland and Canada, the company leverages two key advantages: abundant renewable energy and naturally cold climates.
Iceland’s geothermal and hydroelectric power provide cheap, sustainable electricity — crucial for energy-intensive mining operations. The sub-zero temperatures allow for passive cooling, reducing the need for expensive air conditioning systems.
While Genesis doesn’t disclose exact farm locations due to security policies, reports suggest it may be one of Iceland’s largest electricity consumers. Its move toward transparency through cloud mining services lets individual investors participate without owning physical hardware.

3. Dalian Mining Farm – China
- Founded: 2016
- Location: Dalian, Liaoning Province, China
- Monthly Output: ~750 BTC
- Hashrate: 360,000 TH/s (as of late 2017)
- Monthly Electricity Cost: ~$1.17 million
China once dominated global Bitcoin mining — and Dalian was at the heart of it. This three-story facility contributes over 3% of the entire Bitcoin network’s hashrate, powered by tens of thousands of ASIC miners.
China’s dominance stemmed from several factors:
- Access to low-cost mining hardware (many ASICs are manufactured locally)
- Government-subsidized electricity for industrial users
- Low labor costs, with technicians living on-site in dormitories
Though Chinese authorities later cracked down on crypto operations, provinces like Sichuan continued leveraging hydroelectric power to run large-scale farms near dams. One such facility reached 12 PH/s by 2019 before regulatory shifts forced relocations.
4. Swiss Mining Farm – Linthal, Switzerland
- Founded: 2016
- Location: Linthal, Switzerland
- Hashrate: Undisclosed
Guido Rudolphi moved his mining operation from Zurich to Linthal after finding energy costs too high. In this small alpine village, he found access to some of Switzerland’s cheapest hydro-powered electricity.
Housed in a former factory, this farm prioritizes sustainability and long-term vision over short-term profit. While cooling remains a challenge, Rudolphi views Bitcoin as a transformative technology — comparable to the early internet — essential for financial sovereignty and decentralization.
Switzerland’s pro-innovation regulatory environment makes it a haven for blockchain ventures, further supporting such initiatives.
5. Russian Mining Farms – Near Moscow
- Monthly Output: ~600 BTC
- Hashrate: 38 PH/s
- Monthly Electricity Cost: ~$120,000
Russia hosts several large-scale mining operations, with one of the biggest believed to be near Moscow. This secretive farm runs 3,000 Antminer S9 units, requiring advanced Icelandic ventilation systems to manage heat output.
Despite harsh winters, Russia’s low electricity prices and lax enforcement made it attractive for miners — though recent regulations have increased scrutiny.
Still, many operators continue running semi-covert farms powered by industrial-grade infrastructure, contributing significantly to global hashrate distribution.
Frequently Asked Questions (FAQ)
Q: Why do mining farms prefer cold climates?
A: Cold environments naturally cool down overheating hardware, reducing reliance on energy-intensive air conditioning systems and lowering operational costs.
Q: Is Bitcoin mining still profitable in 2025?
A: Yes, but only at scale. Individual miners face slim margins due to high electricity and hardware costs. Large farms with access to cheap power and efficient infrastructure remain competitive.
Q: How does electricity cost impact mining profitability?
A: Electricity is the largest ongoing expense in mining — often consuming 30–60% of revenue. Locations with sub-$0.10/kWh rates offer a decisive advantage.
Q: Can anyone start a mining farm today?
A: Technically yes, but profitability requires significant capital investment in hardware, cooling, and low-cost power sources. Most new entrants opt for cloud mining instead.
Q: What happens when all Bitcoin is mined?
A: Miners will rely entirely on transaction fees for income. By then, Bitcoin’s value and transaction volume are expected to sustain network security.
