Pourquoi le choix du bon mineur Bitcoin est important
Not all Bitcoin miners are created equal. The miner you choose determines everything: your hashrate contribution to the network, your electricity costs, your noise levels at home, and whether you can realistically run the machine in a residential setting. A wrong choice means wasted money, frustrated neighbors, and tripped breakers. A right choice means years of productive hashing, supplemental heat for your home, and direct participation in the most important decentralized network on the planet.
At D-Central Technologies, we have been Bitcoin Mining Hackers since 2016. We have personally built, repaired, modified, and deployed every category of miner listed on this page. This comparison is not a spec sheet pulled from manufacturer marketing. It is informed by thousands of hours of hands-on work in our Canadian repair facility, real-world noise measurements in residential environments, and actual power consumption data from our workshop and hosting operations.
Whether you are a complete beginner looking for your first solo miner, a home miner wanting to heat your house while stacking sats, or an experienced operator scaling up with industrial ASICs, this comparison guide will help you find the perfect miner for your specific situation.

Chaufferettes Bitcoin — minez et chauffez votre maison
D-Central’s Space Heater Editions are custom-built ASIC miners enclosed in insulated, fan-silenced cases designed for residential use. Every watt of electricity consumed by a miner converts to heat — so why not use that heat to warm your home? These units turn a « cost » (electricity for mining) into a « benefit » (free heating plus Bitcoin rewards).
| Model | Base Miner | Algorithm | Hashrate | Power / Heat Output | Noise | Voltage | Price Range |
|---|---|---|---|---|---|---|---|
| S9 Space Heater | Antminer S9 | SHA-256 | ~11–14 TH/s | ~1,100–1,400 W | Quiet (silenced) | 220V | $400–$600 |

Comparer par cas d’utilisation : quel mineur est fait pour vous ?
Minage solo / minage loterie
Solo mining means pointing your miner at a solo mining pool (like CKPool Solo) and mining independently. If your device finds a valid block, you keep the entire block reward — currently 3.125 BTC. The tradeoff: lower hashrate means lower probability per unit of time. But solo mining is fundamentally about sovereignty and decentralization, not guaranteed daily payouts.
Meilleurs choix pour le minage solo :
- Entry level (under $50): Nerdminer — silent USB device, educational and fun, nearly zero power cost
- Sweet spot ($80–$150): Bitaxe Supra/Ultra/Gamma — real ASIC chips, silent operation, desk-friendly
- Maximum open-source ($300–$800): Bitaxe Hex, NerdQAxe++, or NerdOctaxe Gamma — highest hashrate while keeping the open-source solo mining spirit
- Serious hashrate ($2,000+): Antminer S21 pointed at CKPool Solo — industrial hashrate, real block-finding probability

Minage en pool / récompenses constantes
Pool mining splits your hashrate contribution with thousands of other miners in exchange for regular, proportional payouts. If you want predictable daily sats, pool mining with a full ASIC is the most practical approach.
Meilleurs choix pour le minage en pool :
- Budget ($400–$800): Antminer S19 or Slim Edition — proven machines with ample hashrate
- Mid-range ($800–$2,500): Antminer S19 XP or S19k Pro — excellent efficiency at reasonable cost
- Maximum ROI ($2,000–$7,000): S21, S21 Pro, or S21 XP — cutting-edge efficiency means lower electricity cost per TH

Chauffage domestique + minage (double usage)
Every watt a miner consumes becomes heat. D-Central’s Space Heater Editions enclose miners in insulated, fan-silenced cases so the heat is directed into your living space while noise stays manageable. In Canadian winters, this is not a gimmick — it is the most cost-effective way to heat a room because the « electricity cost » generates both warmth and Bitcoin.
Meilleurs choix chauffage + minage :
- Small room / apartment: S9 Space Heater Edition (~1,350 W) — equivalent to a standard space heater
- Medium room: S17 Space Heater Edition (~2,000 W) or L7 Pivotal Heater (~1,300 W)
- Large room / workshop: S19 Space Heater Edition (~3,250 W) — serious heat output plus serious hashrate
- DIY build: BitChimney DIY Kit or Space Heater XL DIY Case — build your own custom setup

Comparer par niveau de bruit
Noise is the number one concern for home miners. Here is an honest breakdown based on our direct measurements and experience.
| Noise Level | Decibels | Description | Miners |
|---|---|---|---|
| Silent | <25 dB | Completely inaudible in a quiet room. Can sit on your desk next to you while you work. | Nerdminer, NerdNOS, Bitaxe Supra/Ultra/Gamma, NerdAxe |
| Quiet | 25–40 dB | Comparable to a desktop computer or quiet fan. Noticeable in a silent room but not disruptive. | Bitaxe GT, Bitaxe Hex, NerdQAxe/+/++, S9 Space Heater, L3+ Space Heater, L7 Pivotal Heater |
| Moderate | 40–55 dB | Like a conversation or a window AC unit. Fine for a separate room, basement, or garage. | NerdOctaxe Gamma, S17/S17+ Space Heater, S19 Space Heater, Antminer Slim/Pivotal/Loki Editions (with shrouds) |
| Loud | 70–80 dB | Industrial. Requires a dedicated room, garage, or basement with sound insulation. Not livable without shrouds and ducting. | All full ASIC miners (S9, S17, S19, S21 series, Whatsminer M30S++) |
Conseil pro : Loud full ASICs can be tamed with D-Central shrouds, custom ducting, and silencers. We also sell 120mm to 140mm adapters that allow use of larger, quieter aftermarket fans. See our Noise Reduction Guide for detailed strategies.
Comparer par consommation électrique
Electricity is the single largest ongoing cost of Bitcoin mining. Understanding power consumption determines whether a miner is profitable in your location and whether your home electrical system can handle it.
| Power Tier | Wattage | Monthly Cost* | Circuit Requirement | Miners |
|---|---|---|---|---|
| Negligible | <5 W | <$1 | USB port | Nerdminer, NerdNOS |
| Minimal | 5–30 W | $1–$3 | Any outlet (5V adapter) | Bitaxe Supra/Ultra/Gamma, NerdAxe |
| Low | 30–120 W | $3–$12 | Any outlet (12V adapter) | Bitaxe GT, Bitaxe Hex, NerdQAxe series, NerdOctaxe Gamma |
| Moderate | 800–1,400 W | $80–$140 | Dedicated 15A/120V circuit or 220V | S9 Space Heater, L3+ Space Heater, Slim/Loki Editions |
| High | 1,400–2,500 W | $140–$250 | Dedicated 20A/120V or 220V circuit | S17 Space Heater, Pivotal Edition, older full ASICs |
| Industrial | 2,500–3,600 W | $250–$360 | Dedicated 220V/30A circuit | S19 series, S21 series, Whatsminer M30S++ |
*Monthly cost estimated at $0.10/kWh (Canadian average). Your actual cost depends on your provincial electricity rate. Use our Mining Calculator for precise estimates.
Important : Power consumption directly correlates to heat output. A 1,400 W miner produces 1,400 watts of heat — identical to a standard space heater. This is why dual-purpose mining + heating makes so much sense in cold climates. Read our 120V Mining Guide and Electrical Requirements Guide for safe wiring practices.

Comparaison d’efficacité : joules par terahash
Efficiency — measured in joules per terahash (J/TH) — determines how much electricity you spend per unit of hashrate. Lower is better. This metric is the single most important factor for long-term mining profitability.
| Generation | Representative Model | Efficiency (J/TH) | Year |
|---|---|---|---|
| Gen 1 | Antminer S9 | ~96 J/TH | 2016–2018 |
| Gen 2 | Antminer S17 | ~45 J/TH | 2019–2020 |
| Gen 3 | Antminer S19 / Whatsminer M30S++ | ~29–34 J/TH | 2020–2022 |
| Gen 3.5 | Antminer S19 XP / S19k Pro | ~21–23 J/TH | 2022–2023 |
| Gen 4 | Antminer S21 | ~17.5 J/TH | 2023–2024 |
| Gen 4.5 | Antminer S21 Pro | ~15 J/TH | 2024 |
| Gen 5 | Antminer S21 XP | ~13.5 J/TH | 2024–2025 |
Ce que cela signifie en pratique : An S21 XP at 13.5 J/TH is 7 times more efficient than an S9 at 96 J/TH. For every dollar you spend on electricity, the S21 XP delivers 7x more hashrate. This is why newer miners are more profitable even though older miners like the S9 are much cheaper upfront.
However, older miners like the S9 still have value as space heaters — the heat output is identical regardless of efficiency, and the low upfront cost makes them excellent heating devices that also happen to mine some Bitcoin.

Foire aux questions
Quel est le meilleur mineur Bitcoin pour les débutants ?
For absolute beginners, we recommend starting with a Bitaxe Supra or Nerdminer. Both are silent, low-power, and connect to your home WiFi for solo mining. The Bitaxe uses a real ASIC chip (BM1366) and delivers meaningful hashrate, while the Nerdminer is an ultra-low-cost educational device. Either one teaches you the fundamentals of Bitcoin mining hands-on. See our Getting Started Guide for a complete walkthrough.
Puis-je miner du Bitcoin à la maison sans 220V ?
Yes. All open-source miners (Bitaxe, NerdAxe, Nerdminer) run on standard 5V or 12V adapters plugged into any household outlet. D-Central’s custom Slim Edition and Loki Edition are specifically designed to run full ASIC miners on 110V/120V circuits. Read our 120V Mining Guide for safe setup instructions.
Le minage solo vaut-il la peine avec un Bitaxe ?
It depends on your definition of « worth it. » A single Bitaxe at 500 GH/s has extremely low probability of finding a block in any given year. But solo miners have found blocks with Bitaxe devices — it happens. Solo mining is about sovereignty, supporting decentralization, and the thrill of the lottery. If you are looking for guaranteed daily returns, pool mining with a full ASIC is more predictable. If you believe in the principle that chaque hash compte and want to support the network independently, solo mining is deeply rewarding.
Quel est le vrai niveau de bruit des mineurs ASIC ?
Stock full-size ASIC miners (Antminer S19, S21, Whatsminer M30S++) run at approximately 75 dB — comparable to a vacuum cleaner running continuously. This is not livable in the same room. However, with shrouds and ducting, noise can be reduced to 50–55 dB. D-Central’s Space Heater Editions are specifically designed to manage noise for residential environments.
Quel est le mineur Bitcoin le plus efficace disponible ?
As of early 2026, the Antminer S21 XP leads with approximately 13.5 J/TH efficiency. The S21 Pro follows at approximately 15 J/TH. Both represent massive improvements over previous generations. For context, the S9 was 96 J/TH — meaning the S21 XP delivers over 7 times more hashrate per watt of electricity.
Puis-je vraiment chauffer ma maison avec un mineur Bitcoin ?
Absolutely. A miner that draws 1,500 watts produces exactly 1,500 watts of heat — the same as a conventional electric space heater. The difference: a conventional heater only produces heat, while a mining heater produces heat and Bitcoin. D-Central’s Space Heater Editions are enclosed in insulated cases with directional airflow, designed to distribute warm air into your room. In Canada, where heating is essential for 6+ months per year, this is one of the most compelling use cases for home mining.
Quel mineur a le meilleur retour sur investissement (ROI) ?
ROI depends on your electricity cost, Bitcoin price, and network difficulty. Generally, newer-generation miners with better efficiency (lower J/TH) have faster ROI timelines because their electricity cost per TH is lower. Use our Mining Profitability Calculator to estimate ROI based on your specific electricity rate. In cold climates where the heat displaces conventional heating costs, the effective ROI of space heater editions can be significantly better than raw mining profitability numbers suggest.
D-Central répare-t-il les mineurs ?

Quelle est la différence entre Antminer et Whatsminer ?
Antminer is manufactured by Bitmain (the market leader), while Whatsminer is manufactured by MicroBT. Both produce high-quality SHA-256 ASIC miners. Key differences: Antminer has a larger aftermarket ecosystem (more third-party firmware, parts, accessories), while Whatsminer units are known for robust build quality and competitive efficiency. D-Central carries both brands and repairs both. See our Whatsminer vs Antminer Comparison and Whatsminer Hub for detailed analysis.
