Extremely Disappointing Experience with CompassMining.io - Avoid at All Costs!*

We have been using CompassMining.io since January 2022 and our experience has been nothing short of a nightmare. CompassMining.io is a Bitcoin mining company where you can purchase your own mining equipment, and they provide hosting services for these devices. Monthly fees include electricity and hosting charges. However, our experience has been fraught with issues that have led us to write this very negative review and customer feedback.

**Terrible Customer Support*\*

The support provided by CompassMining is an absolute disaster. Our miners frequently go offline, and when we contact support, it often takes up to three months to get a response. Regardless of the type of support request, we face weeks of waiting before getting any feedback. We own six miners through CompassMining, and since January 2023, not a single time have all six miners been operational simultaneously. Additionally, CompassMining frequently relocates miners to different sites, resulting in downtimes of up to three months.

**Non-Existent Monitoring and Service*\*

The monitoring and service at CompassMining are equally abysmal, essentially non-existent. Miners suddenly go offline or operate at a reduced hashrate without any proactive measures from CompassMining. If we didn’t notify them, nothing would happen, and the miners would remain offline or continue running at reduced capacity. Upon notifying support, it takes weeks for them to acknowledge the issue and even longer to resolve it.

**Specific Incident with a Miner*\*

One particular incident involves one of our six miners. It initially ran for only a few weeks before failing. We reported this to CompassMining, who took months to respond and eventually sent the miner for repairs. After several months, the miner was returned, only to fail again within weeks. We reported the issue once more, but months went by before CompassMining responded, only to inform us that the warranty had expired. They offered us the option to either decommission the miner or upgrade to a new one at our expense. This is ludicrous, given that the miner was operational for just a few weeks and was offline for more than nine months due to their negligence. The warranty expired due to their lack of timely support, despite our continuous notifications.

**Disparity in Service Based on Customer Size*\*

For customers with a large number of miners, these issues might not seem as significant. However, for smaller customers like us with a limited number of miners, the impact is substantial.

**Prompt Billing Notifications*\*

Interestingly, if you are late with a monthly payment by even a single day, CompassMining’s support team suddenly becomes extremely responsive, contacting you within a day to remind you of the overdue payment and threatening penalties.

**Performance Analysis*\*

The attached graph clearly illustrates the abysmal performance and inconsistency of CompassMining’s services. The green line represents the expected hashrate based on our contract, while the red line shows the actual average hashrate per month. The blue line indicates the daily average hashrate. As depicted, there is a significant and consistent discrepancy between the contracted hashrate and the actual performance, with numerous and prolonged downtimes. This visual evidence underscores the reliability issues and the lack of effective monitoring and response from CompassMining.

**Final Recommendation*\*

Given our extremely poor experience, we cannot recommend CompassMining’s services to anyone. If you value your time, money, and sanity, look elsewhere for your Bitcoin mining needs. Avoid CompassMining.io at all costs!
