The cryptocurrency market has endured prolonged turbulence over the past two years, with uncertainty lingering around every corner. Yet amid this so-called "crypto winter," a surprising trend is emerging: new bitcoin mining operations continue to launch, backed by significant investments and bold technological innovation.
Despite the broader market slowdown, interest in the potential returns of bitcoin mining remains strong. Investors are pouring millions into increasingly powerful mining rigs—specialized processors that secure transactions and mine new bitcoins. The latest entrant in this space has even attracted support from one of Silicon Valley’s most renowned figures: Peter Thiel, co-founder of PayPal and early investor in Facebook.
His backed startup, Layer1, announced on February 19 that its first large-scale bitcoin mining facility is now operational. Spanning over 30 acres and representing a multi-million-dollar investment, the project underscores growing confidence in the long-term viability of blockchain infrastructure—even during market downturns.
The Resilience of Bitcoin Mining Through Market Cycles
Back in 2017, the bitcoin bubble burst dramatically. After peaking near $20,000, the price plunged to as low as $3,500 before gradually recovering to hover around $10,000. While the rebound has been slow and uneven, mining activity has defied expectations.
This period—often referred to as a crypto winter—has seen depressed sentiment across much of the digital asset ecosystem. However, bitcoin mining has emerged as a notable exception. Companies like Hut 8, Bitmain, and Bitfarms have all expanded or launched new mining facilities in 2019 alone.
One key indicator of network health—the hash rate, which measures the total computing power securing the bitcoin blockchain—has more than doubled over the past year. This surge reflects sustained investment and confidence in the mining sector.

How Bitcoin Mining Works: From Math Problems to Digital Gold
At its core, bitcoin mining involves validating transactions and adding them to the public ledger, known as the blockchain. Every ten minutes, miners compete to solve complex cryptographic puzzles—known as hashing problems. The first miner to solve the puzzle earns the right to add a new block of transactions and receives a fixed reward in bitcoin.
Currently, that reward stands at 12.5 bitcoins per block, worth approximately $125,000 at current valuations. In theory, anyone with a computer could mine bitcoin from home. But in reality, the process has become highly industrialized due to escalating competition and hardware demands.
Modern mining relies on Application-Specific Integrated Circuits (ASICs)—ultra-efficient chips designed solely for hashing. As these devices evolve rapidly, miners must constantly upgrade to stay competitive, making operational efficiency crucial for long-term survival.
Why West Texas? The Power Behind Profitable Mining
Layer1’s choice of location may seem unusual: a remote site about 100 miles west of Midland, Texas. But for large-scale mining operations, energy cost is the single biggest expense—and West Texas offers some of the cheapest bulk electricity in the world.
According to Alexander Rea, CEO of Layer1, “The cheapest large-scale power globally right now is right here in West Texas.” This affordability stems from several factors:
- Deregulated energy markets
- Overproduction of natural gas via hydraulic fracturing
- Significant investment in wind energy
- State-level subsidies for renewable projects
Rea notes that wind power forms the backbone of Layer1’s energy supply, supplemented by natural gas generation. This blend supports both sustainability goals and cost efficiency—an increasingly important balance in an environmentally conscious era.
However, there’s a major challenge: heat. Midland regularly experiences temperatures above 100°F (37.7°C) for nearly half the year. High ambient heat can damage sensitive electronics and reduce mining efficiency.
While some companies opt for cooler climates—like Iceland or northern regions—Layer1 is taking a different approach.
Liquid Cooling: A Game-Changer for High-Temperature Mining
Traditional mining rigs resemble what Rea calls “shoeboxes”—long rectangular boxes cooled by fans at one end. But Layer1 has developed proprietary hardware designed for immersion cooling, where machines are submerged in oil-based dielectric fluids.
This method isolates components from external heat, significantly improving thermal management. It also allows for overclocking—running chips at higher performance levels without overheating—extending hardware lifespan and boosting output.
“With liquid cooling,” Rea explains, “we can maintain low operating costs regardless of outside temperature. That’s our competitive edge.”
As newer ASIC models flood the market, capital expenditures rise. But Rea believes the race is shifting from hardware upgrades to operational efficiency. Over time, facilities with access to cheap power and advanced cooling will dominate.

The Upcoming Halving: Threat or Opportunity?
Bitcoin’s next major event looms within three months: the block reward halving. Approximately every four years (not three, as previously misstated), the network cuts miner rewards in half—a built-in mechanism to control inflation and limit total supply.
This time, the block reward will drop from 12.5 BTC to 6.25 BTC per block. Historically, such events trigger market volatility and force less efficient miners offline due to reduced profitability.
Older, power-hungry equipment becomes economically unviable, leaving room for optimized operations to capture greater network share. Some analysts predict that reduced issuance could drive up bitcoin’s price—a phenomenon observed after previous halvings.
For Layer1, this transition isn’t a threat—it’s a strategic advantage.
“We’re not worried about the halving,” says Rea. “We’re focused on beating our competitors.”
With low-cost renewable energy and innovative cooling systems, Layer1 is positioning itself to thrive when others scale back.
Frequently Asked Questions (FAQ)
Q: What is bitcoin mining?
A: Bitcoin mining is the process of verifying transactions and adding them to the blockchain. Miners use powerful computers to solve cryptographic puzzles and are rewarded with newly minted bitcoins.
Q: Why is electricity cost so important in mining?
A: Electricity is the largest ongoing expense for miners. Lower energy costs directly increase profit margins and allow operators to remain competitive during price downturns or reward reductions.
Q: What happens during a bitcoin halving?
A: Every four years, the number of bitcoins awarded to miners per block is cut in half. The next halving will reduce rewards from 12.5 BTC to 6.25 BTC per block.
Q: Can small miners still compete with large operations?
A: It’s increasingly difficult. Industrial-scale miners benefit from economies of scale, better technology, and cheaper power, making it hard for individuals to profit without joining mining pools.
Q: Is liquid cooling widely used in mining?
A: Not yet—but it’s gaining traction. Immersion cooling improves efficiency and hardware longevity, especially in hot climates, making it ideal for next-generation data centers.
Q: How does renewable energy impact bitcoin mining?
A: Renewable sources like wind and solar reduce environmental impact and often offer lower long-term costs. Many modern mines prioritize green energy to improve sustainability and regulatory compliance.
Looking Ahead: Efficiency Over Hype
While bitcoin prices remain volatile, success in mining increasingly depends on cost control, energy sourcing, and technical innovation rather than speculation alone.
For startups like Layer1, the crypto winter isn’t a reason to retreat—it’s an opportunity to build resilient infrastructure that can outlast market cycles.
As competition intensifies and rewards shrink, only those who master operational efficiency will survive.
