Bitaxe Gamma 602 Bitcoin Solo Miner with Dark Horse Upgraded Heatsink - 1.2TH/s BM1370 ASIC, Wi-Fi, Plug & Play - Assembled in USA with All Accesories Included - Solo Satoshi

Bitaxe Gamma 602 w/Darkhorse Units has great performance ( at or above 1.2/th ) 3d Printed stand is of great quality. DarkHorse heatsink definitely keeps it cool. Fan runs quietly, if not order the Noctua NF-A4x20 5V PWM, Premium Quiet Fan, 4-Pin, 5V Version (40x20mm, Brown) Very simple setup, just make sure you have your bitcoin address ready. You will need to add it. ( Running a 21-watt device continuously for a year in Spring, TX, where the 2025 average electricity rate is about 15.5 cents per kWh, would cost approximately $28.54 for the entire year. ) Not bad for solo mining a device that has a possibility to make you earn 3 Bitcoin. Costs less than purchasing your regular tickets for Mega Millions or Powerball for the year. SoloSatochi is the way to go.

Great little product, it sits on my desk while I work, I love logging into the dashboard to see it chugging along. At first the fan always was on 100% even though my room is cool, I noticed the heatsink was not fully seated, probably moved a little bit during shipping. After I reseated it this thing is quiet now, the fan runs at 60% probably because of the upgraded heatsink. It was easy to get going, and it is fun to look at. I am probably going to buy another just because it has been such a great experience.

neat little btc miner. just have mine running solo because im feeling lucky!! easy setup and quite.

D.O.A. zero quality control zero support deservs Zero stars, Had to Issue a stop payment and demand a free pickup of the garbage they sell. Amazon support playing dumb like I had no recourse in their terrible, convoluted return process of the none working garbage they sold.

Setup same as 601 easy, runs cooler than 601's. Same TH/s and just great little miner. Very pleased with 602 will buy more. Also arrive 2 days before delivery date. Same speed, runs cooler and very quite, nice upgrade.

Price was very fair. First shipment, the unit didn't work properly. The return was easy and my issue was quickly resolved with a replacement that is working flawlessly. Would definitely buy from them again due to the very good customer service which is a primary reason for me giving them 5 stars. I use it for solo mining. No, I haven't found a BTC block. Fingers crossed.

Easy setup. Fun way to pretend to be into bitcoin mining. Appears to use low wattage.

So here is the real deal. This is a lottery ticket type item. Low electricity cost for an exceptionally low chance at finding a block. What is a block? Simply put, it is a chance at winning ~3 bitcoin before fees. So how bad are the odds? Well this runs at about 1-1.2 TH/s. Global Speed as of writing this is close to 800 EH/s. Huh? What's that mean? Well it means that to match the global speed, you'd need ~800 million of these. Those numbers just continually get worse. Every single day massive farms are adding huge amounts of hardware that truly make your chances of finding a block almost zero. But hey. Almost zero isn't zero. There is a chance and just like with powerball or mega million you don't buy a ticket because you think you will win. You almost certainly won't. You buy it for the dream. You buy it so you can imagine how you'd spend it. This is like that only at a much smaller scale since the potential reward is so much lower. This also has the added benefit of being very educational. From setting up a wallet, exchange account, to configuring the miner and learning about pools, it will give you a nice crash course in crypto. I bought 2 for myself and 1 for a gift. I enjoy it a lot. It's a wonderful little toy for the aspiring or hobby miner.
