I invested $50k in 4 S19 Pro 100TH… I invested $50k in 4 S19 Pro 100TH miners since 2022. It took 6 months for them to start running after the initial investment. However, they only ran for a few days before shutting down. Correspondence via email took up a lot of time. Overall, the running time of the miners was significantly less than the downtime. So far, I've earned about $7k, not including increasing hosting fees and occasional repair costs. It's exhausting. I'd rather have spent $50k buying Bitcoin; I might have made a profit. The company lacks credibility. I trusted what they said initially, so I boldly placed my money in their hands, hoping for mutual benefit, but I was wrong. I lost sleep worrying about it. I still paid the hosting fees promptly when they sent me a bill, but they kept making promises month after month while my machines were not operational.

The miners are almost always offline The miners are almost always offline. Bought 6 miners that went online about a year after the scheduled date, they mined for about 1 year (constantly on and off, almost never had all 6 online). My $50k investment turned $16k (just thank to Bitcoin price going up) and now with the halving coming up the miners are obsolete. Don’t get scammed

Good and accurate support and help Lea at Compass Mining had helped me with a question about placing the newly purchased miners on a different mining pool and I was very happy with the quick headsup and accurate information given to me by Lea !!! Everyone at Compass mining starting from John Degnan in Sales to all of the Support Team get a 5 Star ***** Review from me !!! Compass Mining has made it easy for me to mine Bitcoin !!! Wonderful people and company who are as real and everyday people just like me !!! I will be buying a third batch of miners in 2024 January !!!

Biggest scam in BTC space. Customer support is non-existent Customer support is non-existent. Takes weeks to reply, and months to actually get your miner back running. They have zero interest in keeping your miner running, but very interested in selling you a miner at the beginning. Avoid.

Such a disappointing experience My miner has been offline for over a year. When I ask about it, weeks go by before I get a response. I have checked in consistently during this time and have had very general responses stating my machine is being fixed. How has it taken a year to get fixed? The machine was expensive and now with the halving, it is such a loss. I am so disappointed with my experience with Compass. I have gone to a different company to continue mining and have all but lost hope for the machine I have with them. They recently said they would request a temporary miner for me (though they are still waiting on a response)- why wasn't that brought up a year ago as an option?
