Buy the Bitaxe Gamma: The Most Efficient Open-Source ASIC Home Miner
Do you want to seriously participate in Bitcoin solo mining without compromising on a closed-source Bitmain miner, but still with ASIC performance? The Bitaxe Gamma is the fifth generation of the Bitaxe project and combines the BM1370 chip (the same chip found in the Antminer S21 Pro) with fully open-source hardware and a simple browser interface. BitcoinStuffStore is an official EU reseller of Bitaxe, so you’re not buying through AliExpress but from a store that knows what it’s selling. The Bitaxe Gamma achieves a hashrate of approximately 1.1 TH/s with a power consumption of about 18 watts. That currently makes the BM1370 one of the most efficient ASIC chips on the market for home use. By comparison, the NerdMiner achieves 77 KH/s at 5 to 10 watts. The Gamma has over fourteen million times more hash power at three times the power consumption and three times the price. If you’re serious about solo mining, this is where you start. I run miners myself, and the Bitaxe Gamma is sitting on my desk.Open source from top to bottom
The Bitaxe project (GitHub: skot/bitaxe) is fully open source and part of OSMU: the schematics, PCB files and firmware are all publicly available. This means you do not depend on a manufacturer that can change its software or discontinue its services. You can repair, update or improve the Gamma yourself. That is the difference with a Bitmain miner: with the Gamma, the hardware is yours in the most direct sense of the word. The AxeOS web interface makes setup easy. You connect the Gamma to your network via WiFi, open the web interface in your browser using the device's IP address, and enter your pool settings and wallet address. No command line, no SSH, no special software required. For detailed setup instructions and firmware version advice, see the Bitaxe Gamma Firmware Guide.Gamma vs the rest: the numbers
