Everything went great. Very friendly and professional support. I would definitely order again, and I think a good business relationship will develop from this. Planning for the next purchase is almost complete and will probably take place in the next few days. Contact with DHL was also professionally established, so that quick arrangements regarding customs and other issues could be made within a day. The miner was shipped from IceRiver on Tuesday, and by 11 a.m. on Friday, it was up and running in the server room. What more could you want?
I'm completely satisfied! The service was competent and friendly, easy to reach at any time, and very helpful. After payment, delivery was lightning fast – faster than expected! A completely reliable provider that I can wholeheartedly recommend. I'd be happy to use again!
Top-notch service, good personal contact, and immediate help should any minor issues arise (though the problem was my impatience :-) ) At Miners.de, everything just works, I'm happy to use them again! Oh, and the product, in my case an S19k Pro, arrived way ahead of schedule, works flawlessly, and is a joy to use. If you're stuck in the rabbit hole, you've come to the right place! Regards, Dennis
Competent advice, top service, and reliable delivery – highly recommended! I've ordered several devices from Miners.de and I'm consistently impressed. I'd particularly like to emphasize the competent advice I received beforehand: The differences and efficiency of the individual miners were explained to me clearly, allowing me to choose the perfect one for my setup. The support was fast, friendly, and very helpful. Delivery was punctual and seamless. All miners are now running reliably and hashing away diligently. Anyone who wants to get serious about home mining is in the best hands here. I definitely recommend them – many thanks to the entire team!

What is an ASIC miner?
An ASIC (Application-Specific Integrated Circuit) miner is a specially designed device optimized for mining a specific cryptocurrency, such as Bitcoin. Compared to GPUs or CPUs, it offers significantly higher computing power and efficiency.
How long does an ASIC miner last?
The lifespan of an ASIC is typically 3–5 years, depending on usage, cooling, and maintenance. Some devices can last longer if well maintained.
Can I buy a used ASIC miner?
Yes, but only from qualified resellers! Used miners can already be very worn. It's important to pay attention to the condition of the hashboards , the fan performance , and proper maintenance.
Energy efficiency in ASIC miners – What does it mean?
The energy efficiency of ASIC miners is measured in joules per terahash (J/TH) and describes how much energy a miner consumes to generate 1 TH/s (terahash per second) of computing power.
Lower J/TH value = Higher efficiency
A miner with 20 J/TH is more efficient than one with 30 J/TH because it requires less power to achieve the same computing power.
