OneMiners Avis 

If i could give zero i would. I was looking through their miner page where you can see the profit of each model. The thing is, it's not actually profit. What they have stated on that page is based off their cheapest electricity costs, which is nowhere stated in fact. Its plastered all over the website that it's profit. What is "profit" you ask? Well that would be base revenue, minus your expenses. The miner they sold be, i chose to be located at a facility they were advertising as a promotional location. Unbeknownst to me, I ended up losing over a dollar a day when it was advertised as $3.50 profit give or take (+/-) 10%. That and they charged me for a day of electricity before i was even able to access my miner. When I talked to them about this, they kept explaining that what is advertised is base revenue, and it is industry standard to call it profit. So i did my homework and looked at all the other sites I could find offering the same kind of services. They all had clearly labeled on their pages that its base revenue, not calling it profit. Completely misleading and refusing to refund me, even though I bought it under false pretenses. Have reported to the FTC and will be following up. All I wanted was a refund. Instead we have turned it into having to report them, put up bad reviews and all the fun stuff, just to get my point across that I will not back down from the bullying tactics. I have everything all documented. Stay far, far away. I mean as far as humanly possible. Put yourself on Mars to get away if need be. Its not worth the headache and high levels of stress you will receive from this company say you run into any kind of problem. They agree that they can see how it is misleading, which has been said over a phone conversation, which led nowhere. The list of bad business practices goes on and on. I could probably write an entire novel about it by now. Hope this is insightful.

Thank you for the support and for taking the time to review my account in detail. I appreciate the transparency in explaining the PayLater balances and the clear breakdown of the numbers. The proposed solution to unblock the account was straightforward and helped me move forward quickly. Communication improved and the guidance made the next steps easy to follow.
Suggestion: it would be great to have a more proactive notification system (e.g., earlier alerts on pending PayLater balances and a clearer “unblock checklist” in the dashboard), so customers can prevent interruptions before accounts are restricted.

Wanted to invest on something that actually provided profit without me needing to do anything. Was initially interested in mining at home but since I have to look at a lot of different stats and since electricity rates at my place was high, it wasn't really ideal for hosting. Then I found out they offer hosting so I tried ordering a few asic and so far, it's been pretty great. Nothing to think about it, just letting it do it's thing as I focus on doing other stuff.

OneMiners (Circlehash LLC) took $21,846.20 in BTC from me in November 2025 for 2 Proto Rigs pre-ordered to be hosted in Nigeria. No hardware was ever delivered. They refuse to refund my money even after I exposed that no order was ever even placed with Proto/Block Inc(!), like they claimed.

Their sales rep Petr Pavelka repeatedly claimed they had placed a bulk order of hundreds -100s - of units directly with Proto (Block Inc.), that the manufacturer stopped responding, and that the rigs (worth millions of dollars) would most likely never be delivered at all by Proto. This all turned out to be completely false and misleading.

My dashboard even showed the rigs “installed” and mining in Nigeria starting mid-January, 2026, with accruing profits — exactly the dates OneMiner’s support had promised me when I asked them when my rigs would go live. Petr Pavelka contacted me soon after, out of the blue, claiming this was due to a “dashboard error.”

OneMiners offered replacement miners with US hosting and significant added fees and other inferior deals, but at this point I wanted nothing more to do with this company. All I wanted was my refund, which Petr kept denying me with stalling tactics.

I contacted Proto directly early on, and they finally replied with a bombshell. Proto/Block Inc confirmed in writing:

-No order (bulk or otherwise) was ever placed by OneMiners/Circlehash LLC.
-Proto/Block Inc. have no third-party resellers or partners — sales are direct only.
-OneMiners is not authorized.
-They (Proto/Block Inc) flagged the situation internally as a scam.

This proves OneMiners fabricated the entire bulk order story.

OneMiners sales rep Petr Pavelka then claimed “he never said they ordered directly from Proto/Block Inc.” Problem is, Proto/Block Inc confirmed there are no resellers, so obviously no order was ever placed.

In my final email, I asked OneMiners sales rep Petr Pavelka for proof that he had placed an order of 100s of Proto Rigs. I received no reply, and has therefore taken the following steps thus far:

I have filed complaints with FTC, FBI IC3, and Texas AG and will continue to warn the community.

Date of experience: November 2025 – January 2026

Thank you for your response.

To clarify a few points:

1) There was no agreement to accept replacement miners. I rejected all offers in writing and demanded refund due to non-delivery. The resale value of the 4x 395 TH S21 Hydros, even if I accepted them (which I don't), is far less than what I would get for 2x Proto Rigs.

2) The "non-refundable" policy does not override the FTC Mail Order Rule (16 CFR Part 435), which requires refund for non-delivery without explicit consent for delay. No shipment occurred, no consent was given.

3) While the dashboard "error" (showing Proto rigs mining on the exact dates promised) was addressed quickly, such a misleading display still significantly erodes trust.

4) Your original emails (see full evidence article link below) explicitly stated a bulk order of 100s of Proto Rigs worth millions was placed with Proto/Block Inc., payment sent, and Proto completely ghosted you, making fulfillment unlikely. Your pre-order money "probably never being returned" was your stated reason for "no refund."

This is far more serious than "unforeseen delays and challenges" — it's an accusation of fraud by a major company.

In a later email, Petr claimed he "never said" OneMiners ordered directly from Proto/Block Inc., which contradicts his earlier messages and also Proto/Block Inc's confirmation of "no resellers".

This begs the questions:

- How can OneMiners sell Proto Rigs without any partnership with Proto/Block Inc.?
- Which company did you place your bulk order with?
- Why did you fail to provide any evidence of such a bulk order when I requested it?

UPDATE: On their request, Proto/Block Inc. legal is currently reviewing all the evidence (order details and correspondence).

Seeking full refund. Filed with FTC, IC3, Texas AG.

Recently bought an S19K Pro with hosting on USA - No Service Fees, little did I know that the electricity charge was way more than the profit of the machine. I had reached out to the Live Chat Support on this matter and it was great that they respond so quickly. Had them checked my issue and said that the machine is running at a high electricity rate which is why I'm having negative profits on the machine. The support was really helpful and gave me options for the machine which is either relocate it or ship it to my address. They even gave me recommendations for my next purchase and I'll keep that in mind if ever I may buy another machine. Overall I had a great experience with them.

Machines are up and running. Customer service is good, especially via WhatsApp and Michaela.
Email responses are a bit slow, but that feels old-school anyway.

Don't do any hosting mining with these people. I bought 3 Avalon 6th from them around 900 dollars and I was waiting for my miners but then I find out oh instead for shipping I did hosting with them oh ok ok well no big deal and now 6 months gone by you know how much I made minus 71 dollars so now instead give me any cent money I made 59 dollars and from there site electricity bill in America hosting on my account is negative 71 dollars and that’s how they took the money and now my account is in minus scammers all are fup scammers

Normally setting up an ASIC is such a hassle and takes way too much time. Thankfully they offer hosting and even a working dashboard for me to see my ASIC at work. So now I don't have to look over at it to check whether there's a problem or not and only have to pay for the energy fees which is also essentially automatic as well, very convenient indeed.

Have been hosting with them for a while now, recently bought another ASIC for hosting and they're basically just making easy money everyday. I don't have to do a thing at all!

Connects properly and easy to setup!

I recently just got my order and it works well, not only was it simple to setup but it worked just as it says in the description. Couldn't be more happy with my purchase!

1 Stern – Im Nachhinein extrem fragwürdig bis betrügerisch

Leider habe ich mir viel zu spät die Mühe gemacht, gründlich nachzuforschen. Erst im Nachgang habe ich über zwei volle Tage hinweg versucht, belastbare Informationen zu sammeln – sowohl eigenständig als auch über E-Mail und den Kundenservice. Verlässliche, konkrete Antworten? Fehlanzeige.

Der beworbene Priority Service ist schlicht nicht existent. Bei keiner meiner Bestellungen wurde das kostenpflichtige 48-Stunden-Fenster eingehalten. Der Support reagiert maximal 1–2 Mal pro Tag, teils gar nicht. Bei Problemen ist man komplett auf sich gestellt.

Die Auszahlungsdauer ist eine absolute Katastrophe, besonders bei größeren Beträgen. Verzögerungen ohne transparente Erklärung scheinen hier Standard zu sein.

Was jedoch alles toppt:
Im Dashboard lassen sich anhand von Temperaturen, Lüfterdrehzahlen und Hashrate eindeutig erkennen, dass diese Werte emuliert und nicht real sind. Ich habe diese Daten über mehrere Tage aufgezeichnet und mit eigenen Minern zu Hause sowie Minern in anderen echten Farmen verglichen. Das, was hier angezeigt wird, ist technisch lächerlich und in keiner Weise plausibel.

Auch die komplette Hochrechnung von Leistung, Stromverbrauch und Ertrag ist nichts weiter als Show & Shine. Reine Zahlenkosmetik ohne reale Grundlage.

Es gibt zudem keinerlei transparente Nachweise über echte Minerfarmen:

keine Fotos

keine Standorte

keine technischen Details

Ein weiterer Tipp an alle: Fragt nach den Seriennummern eurer Geräte. Jeder Antminer besitzt eine Seriennummer – allein schon wegen Garantie und Herstellerzuordnung. Versucht einmal, diese anzufragen, um echte Informationen über eure Miner zu erhalten.
Spätestens danach ist euer Dashboard offline – und euer Geld weg.

Für mich wirkt das gesamte Konstrukt im Nachhinein nicht nur unseriös, sondern hochgradig verdächtig. Ich kann nur dringend davon abraten, hier Geld zu investieren.

Finger Weg!

I had an excellent experience with oneminers. When i call the customer support, they are professional and willing to help with any questions I have.

The entire process was smooth and transparent and they exhibited a high professionalism. They clearly explained everything and they understand the services they are offering.

I highly recommend this brand for anyone looking to buy and host their miners. I will definitely add more miners in the future.

I recently bought an Antminer S19k Pro from oneminers and I absolutely love it. I've got some extra electricity because I have a solar power setup and I'm also rarely at home, so having the miner take up the excess power and also making money while I'm away makes this the best purchase I've made in a long while!

I suggest taking a look at their other available options if you also have extra power around.

I had little to no experience with crypto mining at first. But after watching about their video guides and talking to their support, I was able to get to learn more and even make my first purchase of the Antminer S19 miner with them.

Will definitely make a new purchase on my next payday!

Antminer 234Th, works fine.
Hosting top.

what i really love about oneminers is how straightforward it is.

no fancy nonsense, just "here's your hashrate, here's what you earned today, here's what you got paid last wweek"

everything;s on one page and when i look at it the numbers actually match what i was expecting. it's honestly refreshing because i dont have to sit there scratching my head trying to figure it out

the only part that annoys me is that you cant use your own pool. you're stuck with their own pool. it works fine dont get me wrong but once yu've been mining for a while you start wanting a bit more control, yoou know?

overall though the pool itself runs smooth never had any real downtime and the dashaord is so simple even my mom could probably understand it.

just hoping one day they add a custom pool option so we can have a little more freedom

I am always receiving the proforma invoice even though I already paid the machine so I contacted the support and tell them because this makes me confuse why I need to pay again but they clarified to me that they are having a system bug and there's new feature they are working on and it affected this but to be honest I have a good service experienced with them and acknowledged my concern right away :)

Hello,
I have two machines with Oneminers, all relatively new.

Here is my experience with BTC payouts:

1) I requested a payout on November 1, 2025, the payout was made on November 2, 2025, the payout was made according to their stated terms within approximately 24 hours.

2) I requested a payout on December 8, 2025. Today is December 14, 2025, and the BTC is still nowhere to be found. I have already written to their technical support twice. The first time, they wrote back saying that the payout had to be verified and that it would take several days. The last time, on Friday, they wrote that my request had been forwarded and that I would be informed. Since then, still nothing.

In both cases, the amounts were relatively small, equivalent to about $50, paid to the same BTC wallet address.

What has been your experience with BTC payments from Oneminers recently?

2) The BTC withdrawal requested on Monday, December 8, arrived in my wallet on Monday, December 15, 2025, in the afternoon. That is, one week after the request was made and two reminders to technical support.

Note: Oneminers is NOT the legal company name, it is Circlehash LLC. Go check the reviews for this company BEFORE considering Oneminers.

I honestly can't believe what I experienced with this company, so I’m putting everything here for others to see.

I emailed Oneminers to cancel order #13830 before it shipped and request a refund, $27,092.90. They refused the refund request, citing a “Hosting and Performance Agreement” that I had never heard of. When I looked up the contract on their website, it clearly required signatures from both parties. Since no signed agreement exists, I again asked for a refund. They didn't reply.

It got stranger. The next day their CEO, Michal Beno, called me. Instead of addressing the unsigned contract, he switched to a totally different explanation: because it was a 'futures' order (the miners aren't available until 2026 March), they couldn’t refund me. When I asked him where it said the order was non-refundable, he provided no answer, he simply repeated his explanation. I asked him to put his explanation in writing, he never followed up.

I checked consumer-protection and contract laws in California (where I am), Texas (their listed location), the EU, and the Czech Republic (Oneminers' main location). I couldn’t see how their explanation fit with anything I read.

For example, from my understanding, California Civil Code §1550 says a contract requires the consent of both parties, and Civil Code §1671 describes how any non-refundable deposit terms need to be clearly agreed to in writing.

I sent Oneminers a final email giving them another chance to respond. No reply. Nothing.

I've collected all relevant documents (webpages and documents from their website, emails, call log, including every step of the buying process), and have begun preparing reports to:
- FBI Internet Crime Complaint Center (IC3)
- California Attorney General – Consumer Protection Division
- Texas Attorney General – Consumer Protection Division
- Federal Trade Commission (FTC)
- Policie České republiky – Cybercrime Division
- European Consumer Centres Network (ECC-Net)
- Europol (EC3)

I am also preparing a civil lawsuit in the California Superior Court.

I will update this review if the matter is resolved.

I've been wanting to get my own mining machine but to be honest, it's very hard for me pay the whole price all at once but when I saw them launching the pay later plan, i honestly felt relieved like someone finally undertsood that normal people like me who can't afford to pay a very big amount.

I consider to buy the antminer s21e hyd so instead of paying $5250.98 all at once, i was able to pay $1312.75 only for the first month and will just need to pay the same amount for the next 3 months. It really helped me a lot to not go beyond my monthly budget.

I also found a discount code that also helped me to reduced the payment. I will just share it here just in case you also need it. ONEMINERS_HOSTING_CS_25

I just sent an email to their support to check my order and they replied to me right away and they updated me the date on when my machine will start to run. I don't have to always send them messages because they initiated to update me first with regards to my order.

My machine is now running and earning in Nigeria center. I chose this location because they have the lowest energy rate I've seen compared to others. I am now earning approximately $4 to $5 per day and take note that the energy fee was already deducted.

With my daily rewards, i can save up for my next payment in the following month.

I just want to thank Oneminers because they came up with this feature that can help individual who also want to start mining. This feature is a very big help especially for me.

Thanks 🙏🏻
