Buying a Bitcoin miner: the ultimate 2026 guide
What is a Bitcoin miner (BTC miner)? A Bitcoin miner – often just called a BTC miner or Bitcoin mining device – is a specialized computer built exclusively for mining Bitcoin. Inside sits an application-specific chip (ASIC) that computes the SHA-256 hash function many thousand times more efficiently than a PC or graphics card. Hashrate (TH/s) tells you how much work the unit does, efficiency (J/TH) how much electricity it needs per unit of work – together with your electricity price these two figures decide whether the machine pays off. The best-known manufacturers are Bitmain (Antminer series) and MicroBT (WhatsMiner series). At Mining Technologies we offer models from both manufacturers directly from our warehouse in Germany. Every Bitmain model we sell is compared on our Buy Antminer overview, the MicroBT units on Buy WhatsMiner. If you want to mine Litecoin, Dogecoin or Kaspa instead of Bitcoin, our crypto miner page covers those algorithms; the technology behind every unit is explained under Buy ASIC miner.

Which Bitcoin miner is the best?
There is no single best Bitcoin miner – the best unit is the one that pays off at your electricity price. Cheap or free power favours a low purchase price per TH/s; household tariffs favour the lowest J/TH. Our recommendation by budget: Entry level (from €299): Antminer S19j Pro – 104 TH/s, used from €299; more efficient alternative: S19k Pro from €419. Advanced (from €419): Antminer S19k Pro – 115 TH/s with better efficiency (23 J/TH). Premium (€1,379): Antminer S21 / S21+ – 151-216 TH/s with top efficiency (16.5-17.5 J/TH), the latest generation for maximum profitability.
Is Bitcoin mining worth it in Germany in 2026? Bitcoin mining in Germany can be worthwhile – especially under the following conditions: cheap electricity such as solar surplus (€0) or night-rate power (under €0.15/kWh); heating replacement, because the miner's waste heat replaces an electric heater; a rising Bitcoin price. Tax treatment: depending on its scale, mining counts as commercial or other income – the classification depends on your individual case, so clarify it with a tax advisor. Use our electricity cost calculator to calculate your individual profitability.
Buy new or used? Used: lower entry price, best price per TH/s, ideal for beginners, tested and inspected by us. New: longer statutory warranty (2 years), latest technology, higher efficiency (J/TH), longer lifespan.

S19 price, delivery time and profitability
Prices at a glance: a tested S19j Pro costs 349 € as a single unit, 319 € from three units and 299 € from ten — saving 30 € (from three) or 50 € (from ten) per unit compared with the single-unit price. The S19k Pro starts at 449 € and drops to 419 € from ten units. All prices incl. 19% VAT.
Delivery: S19j Pro and S19k Pro are customs-cleared in our Bavarian warehouse and ship 2–4 business days after payment. Shipping: Germany €19.90, EU €29.90 – both free from €1,000 order value. EU islands €49.00. Switzerland €40.00 (import duties are paid by the recipient).
Profitability with solar surplus: based on our calculator assumption of €0.037 per TH per day, an S19j Pro at 104 TH/s earns about €3.85 per 24 hours – so each kWh of surplus power is worth roughly 5.2 ct when mined. With 6 surplus hours a day it uses about 18 kWh of solar power and earns around €29 a month; with 10 hours about €48. At €299 per unit the S19j Pro pays for itself in roughly 6 to 10 months, and in winter the waste heat also relieves your heating. Bitcoin price and difficulty change these figures constantly.
Which Bitcoin miner fits you?
The decision comes down to three numbers: purchase price, efficiency in joules per terahash (J/TH) and your electricity price per kWh. A cheap used miner at 29 J/TH beats almost any new machine at 10 ct/kWh solar power because the investment returns faster. At 30 ct/kWh household electricity the picture flips and only modern hardware around 17 J/TH stays profitable.
For a first machine we recommend tested used units from 289 €: low entry cost, in stock in Germany and ideal for testing power supply, noise and waste heat in your own setup before spending more.
- Small budget / cheap power: Avalon A1246 85T from 289 € or used Antminer S19j Pro from 299 €
- Best price-to-efficiency ratio: Antminer S19k Pro from 419 € at roughly 23 J/TH
- Maximum efficiency: Antminer S21 with 151 TH/s at 17.5 J/TH, S21+ with 216 TH/s at 16.5 J/TH
- Heat reuse instead of heating cost: Avalon Q with 90 TH/s at 1,674 W as a quiet Bitcoin heater
Calculating electricity cost realistically
A miner draws constant power. A 3,000 W unit running 24/7 uses about 72 kWh per day, roughly 2,160 kWh per month. That is 216 € at 10 ct/kWh and already 540 € at 25 ct/kWh. Your tariff, not the Bitcoin price, decides whether a setup carries itself.
Use our mining calculator to combine hashrate, consumption, electricity price and difficulty for your specific scenario before ordering.
Power supply, noise and location
Most miners need 230 V on a properly rated, separately fused circuit; anything above roughly 3.5 kW belongs on its own circuit. Air-cooled models reach 70–75 dB, so they belong in a basement, garage, workshop, barn or server room rather than a living space.
If you want to heat with mining indoors, choose a Bitcoin heater such as the Avalon Q or Avalon Mini3 Heater: much quieter and sized so the waste heat actually warms a room.
Frequently Asked Questions
What should I look for when buying a Bitcoin miner in Germany?
When buying a Bitcoin miner in Germany, keep these points in mind: 1) Buy from a German warehouse (no customs, no import risk). 2) Prefer tested units backed by statutory warranty. 3) Calculate your electricity cost beforehand (ideally under €0.15/kWh). 4) Compare hashrate and efficiency (J/TH). At Mining Technologies you buy Bitcoin mining hardware directly from Germany – with personal advice and fast shipping in 2–4 business days.
Where can I buy a Bitcoin miner in Germany?
At Mining Technologies you can buy Bitcoin miners directly from our warehouse in Germany. We offer models such as the Antminer S19j Pro from €299, the S19k Pro from €419, and current models like the Antminer S21. Every unit is tested before shipping.
Which Bitcoin miner is best for beginners?
For beginners we recommend the Antminer S19j Pro (used from €299, or the more efficient S19k Pro from €419). It offers 104 TH/s hashrate, is easy to set up, and has an excellent price-to-performance ratio. We provide personal guidance with setup.
Is Bitcoin mining worth it in Germany in 2026?
Yes, Bitcoin mining can be worthwhile in Germany – especially with cheap electricity (e.g. solar surplus) or as a heating replacement. With an Antminer S19k Pro and electricity under €0.15/kWh, profitable mining is possible. How the proceeds are taxed depends on your individual case and should be clarified with a tax advisor.
How much does a Bitcoin miner cost?
Mining Technologies offers Bitcoin miners from €299 (used Antminer S19j Pro in a 10-unit bundle). The more efficient Antminer S19k Pro (used) starts from €419. Premium models such as the Antminer S21+ cost €2.149. All prices include 19% VAT.
Used or new – which Bitcoin miner should I buy?
Used miners offer the best price per TH/s and are ideal for beginners. All our used units are tested. New miners come with a longer statutory warranty period and the latest technology. For maximum efficiency we recommend new units such as the S19k Pro or S21.
How loud is a Bitcoin miner?
Standard ASIC miners produce 70-80 dB and are suitable for a basement or garage. For quiet operation in living spaces, we recommend our Bitcoin heaters (Avalon Mini3 or Avalon Q) at under 35 dB, or water-cooled hydro models.
