Bitcoin Mining Without CAPEX: Why the Pay-as-You-Scale Model Is Replacing Farm Construction

Marathon scaled through hosting. Core Scientific built its own farms and went bankrupt. Why asset-light mining now beats construction for everyone without a sub-$0.03/kWh PPA.

Marathon Digital planned to deploy 73,000 ASICs not in its own data center but in a partner facility operated by Compute North. Core Scientific controlled 143,000 proprietary miners, hosted another 100,000, and commanded 10% of Bitcoin’s total network hashrate. One company chose the hosted model. The other built its own infrastructure. In 2022, the builder went bankrupt.

That outcome was not a coincidence. It was a signal.

The Hidden Cost of Owning: Why CAPEX Kills Speed

Building a mining data center runs roughly $3 per watt of server capacity. A modest 2 MW facility costs at least $6 million in infrastructure alone, before a single ASIC is purchased. Each Antminer S21 XP (270 TH/s) carries a price tag around $6,400, with market prices ranging from $4,000 to $12,000 per unit. A fleet of 300 machines adds another $1.2 to $3.6 million on top.

Money, though, is not the real problem. Time is.

In the United States, securing grid interconnection and permitting for a new facility now averages around five years, and large projects routinely wait seven or more before coming online. Even in friendlier jurisdictions, deploying 2,000 ASICs within existing data centers takes three to six months, and non-standard infrastructure components push timelines further. While you build, network difficulty climbs. By 2025 it reached 148.2 trillion. Network hashrate in Q3 2025 grew to 937 EH/s, up 4% quarter over quarter.

Marathon had the capital to build anything it wanted. Instead, the company extended Compute North an interim credit facility of up to $67 million for a 300 MW partner data center in Texas. Average mining cost came in at $0.0453/kWh, and operations ran 70% carbon neutral. Financing someone else’s facility proved more rational than constructing its own.

Before you commit to a construction timeline, run a simple calculation. Estimate how much Bitcoin you will not mine during the 12 to 24 months it takes to build. Compare that figure to what you would mine if you started within three to six months through a hosted facility. The difference is the true cost of owning infrastructure.

The Compute North Lesson: Why Fixed Contracts Are a Liability Without Fixed Energy

Compute North was the second-largest hosting provider for Bitcoin mining in the United States. Eighty-four clients. Equipment worth $700 million. In September 2022, the company filed for bankruptcy with approximately $500 million in debt against assets valued between $100 and $500 million.

The collapse did not happen because clients left. Compute North lacked long-term power purchase agreements. Client rates were locked in, but energy prices surged through 2022. The company could not raise its rates. It broke.

Electricity accounts for 75 to 85 percent of ongoing mining costs. Industrial miners spend $40,000 to $80,000 on power and hosting to produce a single BTC. Without a PPA — a long-term agreement to purchase a fixed volume of electricity at a fixed price over one to ten years — an operator absorbs raw energy market volatility.

The contrast is stark:

• With a PPA: U.S.-based projects secure electricity below $0.03/kWh, well under the median price for mining operations and roughly a third of average retail rates. Cost predictability extends years into the future.
• Without a PPA: all-in industrial hosting in the U.S. runs $0.065 to $0.08/kWh. Any spike in energy prices erodes margin immediately. That is exactly how Compute North died.

A self-owned data center without a PPA is not an asset. It is an unhedged obligation to the energy market. Hosted partners with long-term PPAs transfer that risk to operators scaled to absorb it.

If you are evaluating construction, the first question is not “where is land cheapest?” The first question is “can I secure a long-term PPA below $0.04/kWh?” If the answer is no, a hosted partner with an existing PPA will deliver better economics and lower risk.

Asset-Light Scaling: Why Tech Giants Choose Partnerships Over Building

Amazon, Microsoft, and TeraWulf are signing massive long-term capital partnerships with existing data center operators. Not because they lack construction budgets. Because waiting three years to bring a new facility online represents billions in foregone opportunity.

Marathon Digital follows the same logic. The largest public miner chose a hosted model not out of necessity but out of calculation. In an industry where network hashrate exceeds 800 EH/s and difficulty surpasses 110 trillion, operational agility has stopped being a competitive advantage. It has become a survival mechanism.

Meanwhile, mining companies that built their own CAPEX-heavy infrastructure are pivoting toward AI. According to CoinShares, publicly listed miners could derive up to 70% of their revenue from AI by the end of 2026, up from roughly 30% today — meaning Bitcoin mining is set to slide from the bulk of these companies’ revenue to a minority of it as AI capacity ramps. For operators sitting on depreciating mining infrastructure, leasing capacity to AI startups is a strategy for salvaging enterprise value.

What does an asset-light operator gain?

• No capital tied to a specific physical site
• Expert infrastructure management handled by the hosting partner
• On-demand scalability, with containerized deployments measured in weeks
• Uptime of 95 to 98% at well-managed facilities
• Jurisdictional and grid diversification across multiple countries

Remote hosting services, according to Coherent Market Insights, will account for 44.2% of the mining market by 2026. When technology giants with effectively unlimited capital choose hosted models for speed, the asset-light approach for mid-market investors is not a compromise. It is the only rational strategy.

Pay-as-You-Scale: The New Institutional Standard

Institutional energy rates, SLA-backed hosting, preferential terms at top mining pools — three years ago, these were available only to operators running their own data centers. Today, hosted partners unlock the same tier of access at ticket sizes that would have been dismissed as unserious not long ago.

CRYPTON operates 600+ ASICs (3.3+ MW, approximately 0.22 EH/s) across Tier-1 partner data centers — Hut 8, Phoenix, Blockstream Mining, BitDeer, DMG, Green Data City — in three countries: Ethiopia, Oman, and Argentina. Clients access the same conditions:

• Contracted energy rates through partners, unavailable to retail miners
• SLA hosting benchmarked at 95 to 98% uptime
• Preferential fee structures and payout models at major mining pools
• Geographic diversification across three jurisdictions, reducing single-country and single-grid risk
• Full turnkey service: equipment sourcing, logistics, installation, monitoring, maintenance
• Dashboard and monthly reports with line-item detail covering revenue, energy costs, pool fees, uptime, and payouts

Consider the contrast. Core Scientific owned its infrastructure, controlled 143,000 proprietary miners, and held 10% of Bitcoin’s network hashrate. None of that prevented bankruptcy. Marathon, operating through hosted partnerships, continued scaling without construction-related CAPEX risk.

Pay-as-you-scale does not mean less control. It means control over costs rather than control over hardware. When hashrate drops or BTC price collapses, a hosted operator scales down. A farm owner cannot.

When to Build: The Only Scenario Where CAPEX Wins

Building your own data center makes sense under exactly three conditions, all of which must hold simultaneously:

1. A long-term PPA below $0.03/kWh. Without it, you repeat Compute North’s path.
2. A ticket above €10 million. Anything less will not cover the fixed costs of design, permitting, construction, and staffing.
3. A planning horizon beyond five years. Bitcoin mining undergoes a halving every four years, difficulty keeps rising, and equipment becomes obsolete. Without a five-year forecast, CAPEX carries too much risk.

If all three conditions are met, building can deliver better economics over the long run. Even then, 24 months of construction means 24 months without mining Bitcoin, during which a hosted competitor is already operating. Difficulty during that window can increase by 20 to 30%.

Argo Blockchain came within days of bankruptcy in December 2022, forced into a distressed sale of its flagship Helios facility to Galaxy Digital for $65 million — plus a $35 million rescue loan — just to stay solvent. Electricity costs had outrun mining revenue. Owning infrastructure, absent a PPA and amid BTC volatility, did not protect the company; it nearly destroyed it.

For the vast majority of investors — tickets from €5k to €500k, horizons of one to three years, no access to a PPA — the hosted model is not a temporary workaround. It is the optimal strategy. Before committing to construction, answer three questions:

1. Do you have a PPA below $0.03/kWh locked in for more than five years?
2. Are you prepared to freeze over €10 million for 24 months or longer?
3. Can you forecast mining profitability across five years, accounting for halvings and difficulty growth?

If even one answer is no, a hosted model will deliver better risk-adjusted returns.

Marathon Digital continues to scale through hosted partnerships. Core Scientific, which owned its infrastructure and controlled 10% of Bitcoin’s hashrate, emerged from bankruptcy only after a painful restructuring, and has since pivoted to AI data centers. These are not isolated cases. They are the trend.

The era of building your own mining farms is ending — not because construction became impossible, but because it became irrational for everyone except operators holding a PPA below $0.03/kWh, deploying over €10 million, and planning beyond five years. For everyone else, the asset-light model delivers better economics, lower risk, and access to institutional-grade infrastructure without CAPEX.

If you are ready to explore the asset-light approach, start with one concrete step: request a full cost breakdown from a hosted partner covering energy, hosting, SLA terms, and pool fees. Compare it against projected construction plus operating costs for the first 24 months. If hosted comes in less than 10% higher but gives you access to hashrate 12 to 18 months sooner, that is not an expense. That is insurance against obsolescence.
