My personal experience with Bitmern potential customers should be aware. I purchased 2 miners from Bitmern in September 2025, investing approximately €8,000. The machines operated for around 3 months. Since then, they have been offline and I have not received the expected mining payouts. What makes this situation even more frustrating is that I personally encouraged my sister to invest in Bitmern as well. Based on my recommendation, she purchased 4 miners. Unfortunately, her equipment ended up in exactly the same situation — the machines stopped operating, and she has also been left waiting without a clear resolution. According to Bitmern’s latest communication, the equipment is currently involved in a legal dispute with a US facility operator, and the company says it is pursuing legal action to recover the machines. From a customer’s perspective, the situation is extremely concerning. We have significant capital invested in equipment that we cannot access or operate, while months have passed without mining income and without a clear, concrete timeline for recovery or compensation. I am sharing this review so that anyone considering purchasing mining equipment through Bitmern can make an informed decision and understand the risks before investing. At this point, based on my personal and my sister’s experience, I would NOT invest additional money with Bitmern until the existing equipment is recovered and a clear resolution is provided to affected customers. I sincerely hope the company resolves this situation properly and transparently. Until then, potential customers should do their own due diligence and carefully consider the risks before committing their money.

A deeply disappointing experience overall. The uptime has fallen significantly short of what was initially promised when investments were being secured. Since March, the miners have been offline, with no clear or consistent communication on when operations will resume. There has also been no transparency regarding whether investors will receive any form of compensation for the prolonged loss of revenue, despite investors having met their financial obligations in full and on time. Based on available information, it appears the company is facing challenges related to its agreements with hosting providers, and there is no evident contingency plan in place. Unfortunately, the consequences of these operational and contractual issues are now hitting entirely the investors. While all investments carry inherent risk, the lack of communication, accountability, and visible recovery plan raises serious concerns about the company’s professionalism and reliability. At this stage, the situation gives the impression of either severe mismanagement or a failure to uphold basic investor commitments. Overall, this experience has significantly eroded trust and raises legitimate questions about the integrity and sustainability of the operation. I'd stay away from them as much as possible...

I am an investor in this company and I purchased 18 miners. My experience has been a total nightmare. The equipment operated at 100% capacity for only 3 months. For the following 3 months, they were underperforming, and since June 2025, half of the miners went completely offline while the rest were barely functional. Despite having a 1-year warranty, not a single unit was repaired; I was constantly met with excuses instead of solutions. Since November 2025, I have been trying to transfer my property to another farm outside the country, but they refuse to release my assets. They even introduced me to a woman named Saron, whom I paid, yet they still refuse to provide the necessary documentation to move my miners. Please note that many of the positive reviews here are fake. They have been posted by company executives, their relatives, or friends—this can be easily verified by cross-referencing their names on LinkedIn and the official Bitmern website. This company is a scam. I am in contact with several other investors facing the exact same issues, and we are proceeding with legal action immediately. Avoid Bitmern at all costs.

Official Response from Bitmern Mining — Addressed by Vice President & Co-Founder Pashalis Pietris We take every piece of client feedback seriously, and given the severity of the claims made in this review, we feel it is our responsibility to respond transparently and in full not through a PR team, but directly. Regarding equipment performance and warranty: Your mining machines are hosted at our facility in Hawassa, Ethiopia, and are fully accounted for. The performance issues you experienced are directly linked to delays at the Bitmain warranty and repair center in Ethiopia an external third party entirely outside of our control. As clearly stated in our contract from day one, Bitmern Mining provides hosting, operations management, and logistics support. We have never offered in-house repairs, and you were fully aware of this from the beginning of our relationship. Bitmain's repair center has, in documented cases, taken up to four months to return machines and in some instances, returned units that required further servicing. This is an industry-wide challenge in the region, not a failure on our part. Regarding the transfer of your property: The claim that we refused to release your assets is simply not accurate. We communicated on numerous occasions and we have the records to prove it that you were free to collect your machines at any time. When you decided to proceed, our team packaged and prepared your equipment and gave you full access. The difficulties that followed are related to Ethiopian regulatory changes introduced in 2025, which significantly restricted the movement and export of mining equipment changes that affected the entire industry and were beyond anyone's control at the time of your contract. One of our senior executives dedicated over 40 hours specifically to your case to assist you through this process, well beyond the scope of our contractual obligations. Your machines were prepared and released as soon as it was operationally and legally possible. Regarding the positive reviews: As a growing startup, it is entirely normal and transparent for a company's own team members who work with the product daily to share their genuine experiences alongside those of clients. None of our reviews are fabricated. Both our CEO and I personally have been on direct calls with you throughout this process. Every member of our team who engaged with your case did so professionally and responded within 24 hours, consistently and without exception. Regarding the scam accusation: A scam involves deliberate deception, theft, or fraud. None of those things occurred here. Your machines exist, they are accounted for, and they were never withheld from you. The challenges you faced, repair delays, export restrictions, and logistical complexity, are real difficulties that exist in the Ethiopian mining landscape in 2025 & 2026. They are not evidence of dishonesty. We have not broken our contract, we have not stolen or hidden your property, and we have not ignored you, not once. We maintained a 24-hour response commitment throughout the entirety of our relationship, including during the most difficult moments. We regret that your experience did not meet your expectations, and we genuinely wish the external circumstances had been different. However, we cannot accept accusations of fraud for circumstances that were outside our control, and we stand fully behind our conduct, our team, and our contracts. Bitmern Mining remains open to resolving any outstanding matters directly and professionally. Pashalis Pietris Vice President & Co-Founder, Bitmern Mining
