Buy Bitcoin Miner from €289 – German Stock
Bitcoin miners from €289: Antminer S19/S21, WhatsMiner, Avalon – shipped from Germany, no customs, delivery in 2–4 business days, 5.0★ rated.
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 319 €
- Best price-to-efficiency ratio: Antminer S19k Pro Mix from 439 € 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.

Shipping, warehouse and delivery time
Stocked units ship within 2–4 business days from our warehouse in Bavaria, Germany. Because the hardware is already imported and cleared inside the EU, there is no import VAT, no customs paperwork and no waiting for air freight from Asia.

New and used miners are covered by statutory warranty under EU law. Used units are tested, cleaned and shipped with a logged hashrate; the exact scope is stated on each product page.
Advice before you buy
We help you check electricity tariff, power connection, cooling, noise and realistic payback before you order — including when the honest answer is that a machine will not pay off at your kWh price. Send us your electricity cost and the planned location and we will run the numbers with you.
