Hosted Bitcoin Mining: Complete Guide

TL;DR. Hosted bitcoin mining = you own the ASIC, the operator hosts it. $0.055-$0.10/kWh typical, plus 100-300$ setup. Contract commits 6-12 months. In the US (Compass, Simple Mining, EZ Blockchain) and EU (La Mine Française, Startmining, BigBlock), several serious operators run hosted mining. 7 contract clauses to scrutinize.

What it actually is

You buy the ASIC. The operator installs it in their datacenter, supplies industrial power, ventilates (or hydro loop), connects internet, supervises 24/7. You stay the machine owner. You receive 100% of mined BTC, minus the hosting fee.

It's the "colocation" model — opposite of "cloud mining" which doesn't give you a physical machine and has a notorious scam history. Distinction detail: cloud mining vs colocation.

Why host rather than run at home

Four concrete reasons, with numbers:

1. kWh rate cut by 2-3x

US residential average: $0.14/kWh. US hosting professional: $0.07/kWh.

On an Antminer S21 Pro (28,500 kWh/year), that's **$2,000/year** difference in electricity. More than the annual hosting fee itself.

2. Noise is dealbreaker

A current-gen air ASIC produces ~75 dB continuous: vacuum cleaner volume, 24/7. Unacceptable in apartments. Challenging in houses without an isolated room (closed-door garage, ventilated basement).

Hydro versions are quieter machine-side (~55 dB), but manifold remains noisy. And hydro requires the datacenter anyway (needs industrial water loop).

3. Heat (3.3 kW) must go somewhere

1 kW electric = 1 kW thermal. An S21 Pro dissipates 3.3 kW continuous — equivalent of three space heaters. Must be evacuated, or thermal throttling and fire risk on residential breaker.

4. Professional uptime beats home

Setup	Average uptime	Annual loss vs 100%
Home (outages, manual reboots, vacations)	90-95%	up to $130 on an S21 Pro
Datacenter with 24/7 monitoring + auto-reboot	> 98%	< $40

Over 12 months, datacenter gains ~10 days of useful production.

What's included in standard hosting

• Dedicated rack space (1U, 2U, 3U depending on machine)
• Industrial power (208V/240V single-phase or 480V three-phase US)
• Forced ventilation (air) or hydraulic loop (hydro)
• Low-latency internet bandwidth to pools
• 24/7 automated supervision (hashrate, stale shares, temperature)
• Remote reboot on software freeze

What's NOT always included

Verify explicitly in contract:

• Preventive maintenance (firmware updates, filter cleaning) — often optional
• Machine SAV: manufacturer warranty + RMA shipping stays on you
• Out-of-warranty repair: billed at time + parts
• Manual reboot outside business hours: sometimes optional
• Theft/fire insurance: rarely included, ~$5-15/month optional
• End-of-contract machine return: shipping typically on you

Pricing models

1. 100% per kWh consumed (most transparent)

Precise sub-metering. No threshold issues. Model to prefer.

2. Flat per-U or per-rack

Fixed monthly with included energy envelope. Above the envelope: surcharge or machine refusal. Less transparent.

3. Setup + variable mix

One-time setup fee + variable kWh rate. Most common 2026 format in US/EU.

Minimum commitment: 6-12 months typical. Early termination penalty: often 50% of remaining months — scrutinize before signing.

Notable operators in 2026

Without ranking (each has specifics):

• Compass Mining (US) — established 2020, multi-site network
• Simple Mining (US) — accessible entry-level pricing
• EZ Blockchain (US/TX) — gas + wind angle, industrial scale
• MiningStore (US) — smaller scale, tailored offerings
• La Mine Française (FR) — partner datacenters France/Finland/Norway
• Startmining (FR) — French operator since 2017, Iceland hydro focus at $0.07/kWh
• BigBlock Datacenter (FR) — French operator, modular capacity
• Apexto Mining — international, multi-site (Iceland, Paraguay, USA)

The 7 contract clauses to scrutinize

1. Locked or indexed kWh rate? If indexed: which index, what revision frequency?
2. Commitment duration. Auto-renewal or hard expiry? Termination notice required?
3. Early termination penalty. Lump sum, percentage of remaining months, or none?
4. Liability on failure. Infrastructure (operator) vs machine (you)?
5. Insurance. Included or optional? Covers what (theft, fire, electrical failure)?
6. Machine return procedure. Time to availability after termination, shipping on whom?
7. Payment terms. Monthly/quarterly, wire/debit, BTC accepted?

What it really costs (example)

Antminer S21 Pro hosted 12 months at $0.07/kWh:

Line	Amount
Consumption: 3.3 kW × 24 × 365	28,908 kWh/year
Electricity: 28,908 × 0.07	$2,024/year
Setup fee (one-shot)	~$150
Year 1 total	~$2,174 ($181/month avg)

What happens if the operator goes bankrupt?

Your ASIC remains your property. The contract must explicitly cover:

• Asset separability clause (hardware out of the bankruptcy estate)
• Reasonable recovery timeline
• Evacuation procedure in case of operator default

Prefer operators with at least 3 years operational track record.

Tax considerations

Mined BTC is ordinary income at receipt in most jurisdictions. In business-treated mining operations, hosting fees + machine depreciation are deductible.

⚠️ For your situation: consult a tax professional. Rules vary by jurisdiction.
