Hosted Mining vs Home Mining: Which Wins?

In short. The rule fits on one line: a rate under $0.12/kWh, genuine tolerance for noise and heat, and no more than one or two air-cooled machines make home viable. Above $0.15/kWh, from three machines up, or with a hydro ASIC, hosting is the only option. In most residential markets, the first condition is rarely met.

Three questions that settle it

Before any detailed comparison:

1. Is your real rate per kWh, taxes and delivery included, below $0.12? Margin hits zero at $0.150, so under $0.12 you keep a safety buffer against a hashprice drop.
2. Can you dedicate a space that absorbs 75 dB(A) and 3.5 kW of heat continuously, across the machine's three-plus years of useful life?
3. Does your electrical installation carry 16 A continuously on a dedicated circuit?

Three yeses make home viable. Two or more noes rule it out.

The twelve-month comparison

Antminer S21 Pro, median 2026 hashprice, accounting for the uptime actually observed in each configuration.

Line	Home, $0.16/kWh	Hosted, $0.07/kWh
Average uptime	92 %	98 %
Annual gross revenue, uptime applied	$4,322	$4,604
Annual consumption	28,288 kWh	30,133 kWh
Electricity cost	−$4,526	−$2,109
Pool fees, 1.5 %	−$65	−$69
Setup fee	not applicable	−$150
First-year result	−$269	+$2,276
Noise in your space	75 dB continuous	none
Heat to evacuate in your space	3.5 kW	none

The annual gap therefore reaches about $2,545 on a single machine, most of it from the electricity rate and the rest from the six extra points of uptime.

What home actually involves

Noise. 75 dB(A) continuously is equivalent to a vacuum cleaner that never stops. That is unacceptable in an apartment, for neighbours as much as for sleep. In a house it stays workable with a closed garage, an isolated outbuilding, a ventilated basement, or a dedicated room away from bedrooms.

Three mitigations exist: a sound enclosure, around $500 for roughly 15 dB gained; an outdoor installation, which removes about thirty decibels on the neighbour's side; and underclocking, which reduces noise at the cost of hashrate. None makes an air-cooled machine compatible with multi-unit housing.

Heat. 3.5 kW is the equivalent of three convector heaters running permanently. In winter, in an electrically heated home, the machine replaces that heating while producing BTC, which is the only configuration where the home calculation turns favourable. In summer you either air-condition, adding its own cost, or move the machine, which assumes you planned a fallback location.

Electrical installation. 3.5 kW continuous is about 16 A at 230 V, or roughly 30 A at 120 V. A standard residential panel carries it, but with thin margin. Plan a dedicated 16 to 20 A circuit, its own breaker, and cabling rated for a continuous load. Budget $300 to $900 of electrical work depending on configuration, before buying the machine. A non-compliant installation on a permanent 16 A load carries a real overheating risk.

Failures. A power cut triggers no automation: restarting happens when you get back. A firmware crash needs manual intervention. Local overheating causes thermal derating that surfaces nowhere and quietly costs hashrate. That is what explains the 92 % uptime used in the table, against 98 % at a professional site.

What hosting changes

Industrial cooling is sized for continuous full-load operation, which removes summer derating. Supervision is automated, with alerts and restarts requiring nothing from you. The kWh rate is halved or better through industrial negotiation. Uptime carries a contractual commitment. And noise, heat, and electrical compliance leave your premises entirely.

In exchange: setup fees of $100 to $350, a six to twelve month commitment, and an early exit penalty whose amount you check in the contract.

Three cases where home still wins

Excess solar self-consumption. Your array produces more than you consume, and that surplus would export at a rate often below $0.10/kWh. Diverting it to a miner monetizes it better, at a marginal cost close to zero. It is the only case where home beats hosting on cash terms.

Mining as heating during the cold season. From October to March, if you heat electrically, producing that kilowatt through an ASIC that also generates BTC beats a passive heater. Out of season the machine has to stop, which cancels part of the annual return. A realistic setup therefore plans a summer location, which is not trivial to find.

Small-scale testing. A Bitaxe around $150, at 1 or 2 TH/s for 15 W, or a used Antminer S9, lets you learn the full ecosystem without commitment. Noise stays moderate and consumption low. The goal is understanding the chain, not earning.

Three cases where hosting is the only option

A hydro-cooled ASIC, S21 XP Hyd, S23 Hyd, or M66S Hydro, requires an industrial water loop no domestic installation provides.

A fleet above two machines, so beyond 7 kW continuous, exceeds what residential ventilation evacuates and what a domestic panel supplies.

An apartment or multi-unit building, where 75 dB and 3.5 kW of heat create a nuisance risk on top of the operational one.
