Thank you, Roger, for taking the time to share your experience and for giving us the opportunity to resolve the Z15 PRO issue. We truly appreciate your trust in OneMiners. We have recently deployed 240 Antminer Z15 PRO machines in the USA, each delivering 860 KH/s of Zcash hashrate, and we are very pleased to see the entire batch operating in excellent condition. As sometimes happens with hardware, a small number of machines can unfortunately arrive with production faults or develop issues during transportation from the factory to the hosting center — Murphy’s law seems to have a special relationship with mining hardware. 😄 Whenever that has happened, we have replaced the affected machines on our side without even having to trouble the customers and without causing unnecessary delays to their mining operations. We believe this is exactly what a professional hosting provider should do. At the moment, the batch is performing particularly well, with rewards running at close to 102% of the expected maximum. Zcash mining can be quite challenging these days because pools can sometimes underpay and shares can be dropped at a surprisingly high rate. Maintaining this level of effective performance is therefore something we are very happy about, and we hope it stays this way. Another convenient feature is that the Zcash you mine can now be withdrawn directly to your own wallet. You can also exchange your mined Zcash for BTC or USD, either through an exchange or conveniently within the OneMiners platform, giving you flexibility over how you use your mining rewards. As usual, our target is 99%+ uptime. And if your uptime ever falls below 95%, we will compensate you accordingly. Even the best hosting provider doesn't have godlike powers 😄 — but fortunately, we do have the resources to compensate our customers when Murphy’s law wins a round. Thank you again, Roger, for your patience, your trust, and for choosing OneMiners. We are genuinely happy to have you mining with us and hope your Z15 PRO continues to run smoothly and profitably for a long time. Michal Beno CEO, OneMiners

Thank you very much, Antonio, for choosing best Bitcoin mining solution. It was also a pleasure to meet you personally. Thank you again for coming to our office and completing your purchase and payment in person. We always appreciate having the opportunity to meet our customers directly and build real, long-term business relationships. I also personally reviewed your miner and its performance after installation. Your Antminer S21+ Hyd 395 TH/s is currently running in excellent condition at our Nigeria #2 hosting location. The miner is delivering its full expected 395 TH/s, its health status is Healthy, and there are currently no overheating issues, hardware faults, or repairs recorded. I personally checked your earnings and electricity consumption as well. On September 2, your miner generated: • 0.00019643 BTC • Approximately $15.16 in gross mining revenue • Electricity cost: approximately $7.47 • Net operating profit after electricity: approximately $7.69 for the day I also verified the electricity billing against the miner's power consumption. Your Antminer S21+ Hyd 395 TH/s operates at approximately 5.9 kW, which means approximately 142 kWh of electricity per day at full operation. At your current electricity rate of $0.0525/kWh, this results in an expected daily electricity cost of approximately $7.47. This matches the electricity charges shown in your account, so I personally verified that everything is calculated correctly. I also reviewed the mining performance. Your approximately $15.16 gross revenue on September 2 is consistent with the expected performance of a healthy 395 TH/s Bitcoin miner under the market and network conditions at that time. Technically, your machine is performing exactly as it should. From the hardware perspective, your miner is also in an excellent state. The machine is operating normally, all hash boards are functioning correctly, and there are currently no reported technical issues or repairs. Your uptime since installation is also close to 100%, which is exactly the operational standard we aim for at OneMiners. With new-generation miners, it is naturally easier to maintain extremely high uptime because the equipment begins its operational life in fresh condition — and our responsibility is to keep it running that way through continuous monitoring and professional hosting operations. 🚀 An option that could further improve your profitability You may also consider our prepaid electricity option, which can provide up to a 30% discount on your electricity price. Your current electricity rate is: $0.0525/kWh With a 30% electricity discount, the effective rate would be approximately: $0.03675/kWh Using your actual September 2 performance as an example: Current setup: • Gross mining revenue: $15.16/day • Electricity cost: $7.47/day • Net operating profit: approximately $7.69/day With the discounted prepaid electricity rate: • Estimated electricity cost: approximately $5.23/day • Estimated net operating profit: approximately $9.93/day That means that although the electricity price itself is reduced by 30%, your net daily mining profitability increases by approximately 29%, based on your actual September 2 mining data. This also improves your estimated ROI time because more of your mining revenue remains as operating profit every day. And there is another major advantage of your OneMiners setup: long-term operational protection. With our 7-year warranty and protection structure, you have a significantly more predictable long-term mining operation. During the lifetime of an ASIC miner, repairs and component failures can potentially create substantial and unexpected costs. I personally verified the operational and performance data of your miner, and everything currently looks exactly as it should. Your machine is healthy, running at full hashrate, electricity billing matches the expected consumption, and uptime is currently close to 100%. Michal Beno CEO of OneMiners

Thank you, Mark — I appreciate the feedback. We’ve recently made several improvements to make the entire process simpler and faster, from a much easier checkout to our Turnkey mining setup. With Priority Processing, Turnkey miners are prepared for installation and targeted to be connected and brought online within 48 working hours on working days. I personally checked your order and the deployment of your Antminer S21e Hydro 332 TH/s. You selected Priority Processing together with our Pay Later installment model. Once our department confirmed and processed the payment for deployment, your miner was installed and brought online within approximately 29 hours. Your Antminer S21e Hydro is currently fully operational at 332 TH/s and reporting a healthy status. The mining connection and monitoring are working normally, with no overheating, malfunction or repair history recorded. Your miner is also covered by our 7-year hardware warranty and guarantee coverage, providing long-term protection for the machine. Covered repairs are handled according to the applicable warranty terms. The first mining results are already visible. On September 1, your miner produced 0.00015781 BTC, with a recorded market value of $12.22 for that day. The reward was credited at 100%. The maximum theoretical possible amount to be mined on that miner on majority of pools is 0.00015775 BTC what is +-1% of the amount what you have received on our account. The separate $7.11 USDT payment represents the applicable electricity/fee charge and should not be confused with the gross mining reward, that corresponds with power consumption of your Bitcoin miner of 5644 Watts per hour - here deviation is within range of +-2%.. Your current electricity rate at our Nigeria #2 facility is $0.0525/kWh. If you choose to prepay electricity, the rate can be reduced to $0.04992/kWh with a 1-year prepaid term, representing a 4% discount. For customers planning to operate long term, our 7-year prepaid option is currently $0.0364/kWh, representing a 30% discount. Importantly, the 7-year prepaid rate is fixed for the full seven-year prepaid period. This means the discounted electricity price is secured for the entire seven years ahead, giving you predictable long-term operating costs rather than being exposed to potential changes in the standard hosting rate. This is one of the advantages of combining Turnkey hardware with long-term hosting: the initial purchase can be structured through Pay Later, while the ongoing operating cost can subsequently be optimized through prepaid electricity. This is exactly what our Turnkey model is designed to achieve: minimize the time between purchasing the hardware and having a real miner installed, connected, configured, monitored and producing. — Michal Beno CEO, OneMiners
