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!

I am new to mining, wanted to start for a long time, but it didn’t work out. After consulting with Promminer, everything fell into place - the guys are professionals: they provided detailed advice, explained all the opportunities and risks, and, taking into account my budget, selected the best ASICs for bitcoin mining. Chose Antminer S19 Pro 110th. Should have contacted this company before. Now I recommend you to all my friends!

We came with a partner, chose ASICs from stock, an excellent assortment of top models! The next day the guys brought the devices and set them up. Excellent service and professional staff, everything was shown and explained. Very happy with the purchase! Thanks a lot! Recommend!

It's already been the third time I bought ASICs from this company. I used to cooperate with them for a few years. Very reliable company with a team of professionals. Great that you've established your office in Dubai. Good luck Promminer and keep on expanding!

I bought from Promminer my favourite ASICs - Antminer S19 110th. Miners show a hashrate higher than stated, which is really great! Very happy with this company's service: they gave prompt consultation, manuals for miners and offered their help with ASICs' maintenance. I'm definitely recommending you to cooperate with this company

It was the first time I bought miners on pre-order, because the ones I was looking for were sold out. Was a bit worried, but my hardware arrived on time as it was agreed. Reliable company and good service. From now onwards will purchase miners only on pre-order, price is better and delivery is fast. Recommending

I'm very satisfied with these guys' service - they kept in touch with me from the first call till I received my ASICs. Was purchasing on pre-order Antminer L7 9050 mh

Very professional team!  I was searching for the alternative ASIC for mining BTC and they gave me advice to purchase Whatsminer from MicroBT. This hardware price is cheaper per terahash than the other famous brands while bringing the same profit. Bought from them Whatsminer M30S 90th which were available and now waiting for my Whatsminer M30S ++ 110th to arrive. Thrilled
