Bitcoin's most recent halving — the roughly every-four-years protocol event that cuts block subsidy rewards in half — has sharpened the capital-allocation dilemma facing mining site owners. Low-cost electricity and ready infrastructure remain valuable assets, but running that power at competitive margins increasingly requires newer-generation ASICs. In Q2 2026, the global hashrate averaged roughly 1,004 EH/s, a 5.8% decline quarter on quarter, while historically low hashprice pushed many older, high-consumption machines offline. For a site owner, purchasing a modern fleet means committing another large capital outlay while accepting the risk that the hardware loses economic value as more efficient generations arrive.

Co-Mining offers an alternative structure: the site partner can contribute power and infrastructure without funding the miner fleet, reducing upfront investment and direct exposure to hardware depreciation while still participating in mining profit. The approach sits within a broader industry shift in which hardware vendors and operators — including hosted-mining and machine-placement arrangements that became common after earlier halvings — have increasingly separated who owns power from who owns machines.

The Heavy-Asset Model Concentrates Too Much Risk

Traditional self-funded mining places nearly every major commitment on the site owner. The operator secures land, power capacity, permits and grid access, then buys the miners, builds out supporting systems, and carries the equipment through its useful life.

That model delivers maximum control, but it also ties capital to assets that can lose competitiveness quickly. The efficiency bar is rising fast — new-generation hydro-cooled ASICs have already dropped below 10 J/TH. As more efficient equipment reaches the market, older fleets face higher electricity costs per terahash, lower operating margins, and weaker residual value.

For a company whose true advantage is access to low-cost megawatts, owning every generation of mining hardware may therefore be an inefficient use of capital.

Co-Mining Changes Who Pays for the Machines

Co-Mining does not alter the underlying economics of Bitcoin mining; it changes which party owns the depreciating hardware.

Bitdeer's Co-Mining framework (bitdeer.com/shop/co-mining) is one example. The site partner supplies a locally compliant facility, available power capacity, and a grid connection. Bitdeer provides the mining hardware along with deployment and operating capabilities, and net profit is shared according to the agreed contract terms. Typical project requirements start at 15 MW for air-cooled deployments and 5 MW for hydro-cooled deployments, with each project assessed individually.

For the site partner, the attraction is not that mining becomes risk-free or capital-free. The advantage is narrower and more practical: there is no need to finance the miner purchase, direct ASIC depreciation risk shifts to the hardware provider, and the site owner still earns a share of mining profit.

Why This Matters for Power-Rich Sites

For operators that already control qualified power and usable infrastructure, Co-Mining can convert those assets into mining revenue without turning the site owner into a recurring hardware investor. Capital that would otherwise be locked into ASIC purchases remains available for substations, electrical upgrades, cooling, site expansion, or other infrastructure with a longer useful life.

The model is already being deployed at industrial scale, demonstrating that shared mining capacity can operate well beyond pilot-project size. Scale, however, should not be confused with guaranteed returns. Project economics still depend on electricity prices, uptime, curtailment, Bitcoin prices, network difficulty, and the final profit-sharing structure.

What Co-Mining Does — and Does Not — Solve

Co-Mining primarily addresses hardware ownership and capital allocation. It does not eliminate exposure to Bitcoin market cycles, network difficulty, or operational performance.

That distinction matters. A site with expensive or unreliable electricity does not become competitive simply because another party owns the miners. But a site with structurally attractive power can avoid layering on a second risk: repeatedly purchasing ASIC fleets that may depreciate faster than the underlying power infrastructure.

For power owners, this creates a clearer division of responsibilities. The site partner focuses on the assets it controls best — power, land, and infrastructure — while the mining operator manages hardware deployment, fleet performance, and replacement cycles. As the next generation of ASICs reaches the market and the network's difficulty adjustment continues to track overall mining investment, the terms of such sharing agreements — and how each party's exposure is defined — will be a key detail for prospective site partners to evaluate.

Final Thoughts

Post-halving mining economics are making capital efficiency as important as energy efficiency. Cheap power remains a competitive advantage, but that does not automatically mean the power owner should also finance and own the machines connected to it.

Co-Mining offers a more asset-light route for qualified sites: lower upfront hardware investment, less direct exposure to ASIC depreciation, and participation in mining profit under an agreed sharing model. It will not suit every project, and it does not remove Bitcoin or difficulty risk. Still, as the post-halving margin squeeze accelerates, the decoupling of power infrastructure from ASIC ownership is no longer merely an alternative — it is becoming an increasingly important benchmark for smart capital allocation in 2026.
