I have been mining for a long time, but there were problems with the mining hotel, I was hosting my devices with the other company. Promminer solved my problem with the placement of ASICs and now devices almost always show uptime of 98-99%. Definitely recommend!

Hey, Promminer! I have been buying from you for a long time and will continue to do so. It's great that you opened an office in Dubai, I can always contact you directly for advice and the necessary service, in particular for my immersion baths. Very pleased with your work!

Promminer was recommended to me by a friend who has been buying ASICs from you for a long time. Quality of goods, delivery, support of company managers, high level of service! I started recommending this company to my friends. Great job!

Guys, I am very pleased with my cooperation with you. Previously purchased from another company, but didn’t like the service. Your managers are in touch constantly, answer all my questions, provide the necessary hardware service. All at the highest level! Keep it up!

For a long time I wanted to start mining and am glad that I found Promminer. They provided detailed advice, helped me choose the ASIC models that fit my budget, set up the ASIC and explained in what conditions the device should be maintained. Now I’m mining myself, so far just with one ASIC, but this is only the beginning as I am still learning all the nuances. I'm sure I'll be buying more.

Due to the lowered exchange rate, I wanted to sell everything and stop mining altogether. I talked with Promminer managers and realized that any drawdown is a great opportunity and bought myself the same devices that I used before, only three times cheaper, thus averaging the cost for hardware. And now I don’t withdraw the mined profit into the cash at the bottom level of the exchange rate, as I did before. Thanks for your professionalism, Promminer!

I have been mining for a long time and have always purchased Antminer before. After chatting with the guys from Promminer, I decided to try another brand, Whatsminer, and am very happy with my choice. The devices are powerful and they show a hashrate higher than the one declared by the manufacturer! Now I will buy only from you! I recommend cooperation with Promminer!

I am delighted with this company, they did not just sell me cool ASICs, but they also provided a complete business plan in regards to which coin is better to invest in / mine. Previously, I did not pay much attention to what to mine, for me the main thing was to earn more, and as a result, I lost almost everything. Now I look at mining differently. Thank you Promminer!
