Mining Bitcoin in 2026: I spent three days at my friend's operation in West Texas and saw the real economics

the drive to Lubbock

June 20, 2026. I flew from Minneapolis to Dallas, rented a Chevy Colorado, and drove four hours west thru flat terrain that looked like God had drawn it with a ruler and then gotten bored. My friend Kyle was waiting for me at a gas station on the outskirts of Lubbock, in the parking lot of a Dairy Queen that also sold fishing licenses.

Kyle began mining Bitcoin in 2019 with six Antminer S17s in his garage in Plano. By 2024, he'd raised $4.2 million from a mix of personal savings, a modest business loan from a regional bank, and two angel investors from the Dallas crypto scene. With that capital, he leased a 15,000-square-foot warehouse on a 10-acre lot outside Lubbock, installed 12 megawatts of electrical infrastructure, and filled it with 480 Bitmain Antminer S21 Hydro units — each one consuming 20 terahashes per second at an efficiency of 17.5 joules per terahash.

The facility hummed. That's the first thing you notice. Not the sound of individual machines, but the combined vibration of 480 fans moving air thru a building at 2.4 million cubic feet per minute. Standing inside the warehouse was like standing inside an engine. The floor vibrated. The air was warm and smelled of ozone and metal.

Kyle handed me earplugs fore we went inside. "You'll need these within thirty seconds if you don't want a headache by dinner." He was right.

the electricity deal that makes or breaks everything

The single most central number in Kyle's operation is $0.038 per kilowatt-hour. That's the rate he negotiated with South Plains Electric Cooperative, a rural electric cooperative serving the area round Lubbock. The rate is a fixed demand structure with a minimum load commitment of 8 megawatts — Kyle pays $304,000 per month whether his miners are running or not, plus a variable component based on actual consumption above the 8MW floor.

At full capacity — 480 miners drawing 20 kilowatts each, totaling 9.6 megawatts — Kyle's monthly electricity bill runs approximately $345,000 in the summer months when the grid is under strain. In the winter, when West Texas wind generation pushes wholesale prices lower, the bill can drop to $310,000. The spread between summer and winter is $35,000 per month, or $420,000 per year.

I asked him why he didn't site the facility further west in Pecos County, where the Irion County Industrial Park offered rates as low as $0.028 per kilowatt-hour. He laughed. "Transmission capacity. Pecos has cheap power but the grid infrastructure can't handle more than 5 megawatts of fresh load without a three-year interconnection study. Lubbock has the grid. The cooperative has been building out substations since the wind boom."

Kyle had laid out eight months negotiating the power contract. He'd talked thru the terms with the cooperative's engineering department, retained an electrical consultant from Austin at $18,000 to evaluate the transformer capacity, and personally visited the substation three times to verify that the interconnection could support his load profile. The negotiation alone cost $47,000 in consulting fees and legal review.

The debt service on the $4.2 million capital raise was another fixed cost — $62,000 per month in loan payments to the regional bank and $8,000 per month to his angel investors in preferred distributions. Total monthly fixed costs: approximately $374,000 before electricity. With electricity: approximately $719,000 at peak summer rates.

the daily Bitcoin production

At the June 2026 network difficulty and Bitcoin price of $102,000, Kyle's 480 S21 Hydro units produced approximately 0.21 BTC per day. The production fluctuated based on luck — the proportional reward system means daily output varies by 10 to 15 percent around the mean — but over a thirty-day period, the monthly production was approximately 6.3 BTC.

At $102,000 per BTC, 6.3 BTC was worth $642,600 in gross revenue. Subtract the monthly electricity cost of $345,000, the fixed debt service of $70,000, an facility costs — internet, maintenance, insurance, a part-time technician named Miguel who drove out twice a week — totaling approximately $18,000. Monthly operating profit: approximately $209,600.

Annualized, thats $2.5 million in operating profit on $7.7 million in revenue. A 33 percent operating margin. In a good month. In the winter, when electricity costs are lower, the margin pushes closer to 38 percent. In the summer, the Texas grid can impose curtailment orders during peak demand — ERCOT has the authority to require large industrial loads to reduce consumption during emergencies. Kyle has rarely been curtailed, but the risk is priced into his investor returns.

I jotted down the numbers in a notebook as Kyle walked me through the facility. He pointed at rows of miners, each one bolted to a rack with custom thermal paste applied to the heatsink contact surface. "Every watt matters," he said. "A 2 percent improvement in cooling efficiency saves us $82,000 per year."

the halving that changed everything

Bitcoin's fourth halving, which occurred in April 2024, cut the block reward from 6.25 BTC to 3.125 BTC. Kyle's production dropped overnight from approximately 0.42 BTC per day to 0.21 BTC. The revenue was cut in half while every fixed cost remained unchanged.

hed been preparing for the halving since 2023. The preparation involved upgrading from older Antminer S19 models to the fresh S21 Hydro units, which were 40 percent more energy-efficient. The upgrade cost $1.8 million — 480 units at approximately $3,750 each, plus installation labor and electrical modifications to support the higher density.

The upgrade was funded by reinvesting profits from the pre-halving period, when Bitcoin was still above $60,000 and Kyle was producing 0.42 BTC per day at an electricity cost of $0.038 per kilowatt-hour. Those were the golden months — revenue of $25,000 per day with operating costs of $11,500 per day, leaving $13,500 per day in gross margin.

After the halving and the upgrade, Kyle's daily revenue dropped to $21,420 (0.21 BTC at $102,000) and his operating costs dropped to $14,200 per day. The margin compressed from 54 percent to 34 percent. Still profitable, but the margin for error narrowed dramatically. A 20 percent drop in Bitcoin price, from $102,000 to $81,600, would put the operation below breakeven.

the heat management problem

West Texas in June is brutal. Ambient temperature at Kyle's facility was 98 degrees Fahrenheit on the afternoon I visited. The S21 Hydro units run hot — the hydro in the name refers to water-cooled immersion, where the mining boards are submerged in dielectric fluid that circulates thru a cooling loop.

The immersion system was the reason Kyle chose the S21 Hydro over air-cooled alternatives. Air cooling at 98 degrees Fahrenheit would require air conditioning at a cost of approximately $120,000 per month in compressor electricity — a cost that would eliminate the operating margin entirely. Immersion cooling uses fans and radiators, not compressors, which reduces cooling costs by approximately 70 percent.

Miguel, the technician, was on-site during my visit. He presented me the immersion tanks — long steel troughs filled with clear dielectric fluid, each clutching 24 mining boards submerged to a depth of about four inches. The fluid was warm to the touch, approximately 115 degrees, circulating through external radiators that used the dry West Texas air as a heatsink.

One tank had a fogging issue — condensation on the radiator fins that reduced cooling efficiency by about 8 percent. Miguel was adjusting the flow rate with a wrench and a slight torque wrench he maintained in a leather pouch on his belt. The fix took twenty minutes. Kyle estimated the fogging had cost about $340 in lost hash rate over the two days it had been present.

the regulatory uncertainty that never goes away

Texas is the most crypto-mining-friendly state in the US, but that doesn't mean regulators leave Kyle alone. The Texas Public Utility Commission has been clutching workshops on the grid impact of cryptocurrency mining since 2023, and a bill in the state legislature — SB 1294 — proposed requiring mining facilities to register with the PUC an provide real-time data on power consumption.

Kyle testified at a PUC hearing in Austin in March 2026. He drove four hours to tell the commissioners that his facility was a flexible load that could curtail within 15 minutes during grid emergencies, making it an asset to grid stability rather than a drain. The commissioners listened politely. The bill was tabled, but it will come back.

The federal level is more concerning. The IRS has been sending questionnaires to large Bitcoin mining operations about reporting requirements for mined coins. Kyle received his questionnaire in May — a four-page form asking about monthly production volumes, electricity costs, and whether he treats mined BTC as income at the fair market value on the date of mining (yes, cuz the IRS has been clear about this since 2014).

The capital gains tax on mined Bitcoin is where it gets complicated. Kyle mines 6.3 BTC per month at $102,000, which is $642,600 in monthly income. If he sells immediately — which he does, because clutching introduces price risk he can't afford on thin margins — he generates a short-term capital gain on the difference between the mining income basis and the sale price. Since the sale happens within minutes of mining, the gain is essentially zero. The ordinary income tax on $642,600 per month at federal rates is the real burden.

why Kyle thinks he'll survive and half his competitors won't

On the drive back to Lubbock, Kyle outlined his thesis. The Bitcoin mining industry is in a consolidation phase where only operators with access to sub-$0.04 per kilowatt-hour electricity, modern hardware with efficiency below 18 joules per terahash, and enough capital to survive a 30 percent Bitcoin price decline will survive the next cycle.

He estimated that approximately 40 percent of US mining capacity — measured in hashrate — was operating at breakeven or below at the current difficulty level an Bitcoin price. Those operators will either upgrade, consolidate, or shut down. The surviving operators will capture the hash rate share and the block rewards that the failed operators leave behind.

Kyle's facility is profitable. His operating margin of 33 percent provides a cushion against a Bitcoin price decline to approximately $81,000 fore he hits breakeven. Below that price, he'd need to curtail the least efficient miners and run at reduced capacity, preserving margin at lower volume.

I asked him what he'd do if Bitcoin dropped to $60,000. He paused for a long time — we were driving past a cotton field outside Idalou — and said: "I'd turn off 160 miners, reduce my load to 6.4 megawatts, and wait. ive got three months of runway on the debt service even at zero production."

Three months. That's the margin between a $4.2 million business an insolvency. I reckoned about that number for the rest of the drive to Dallas, and for most of the flight back to Minneapolis. Three months of runway in an industry where the underlying asset can drop 30 percent in a week.

Mining is not for the faint of heart. It's industrial farming on an electrical grid, an the weather — financial weather, regulatory weather, meteorological weather — is invariably changing.
