Bitaxe Gamma

Overview

The Bitaxe Gamma is the flagship of the open-source Bitaxe project: a palm-sized, silent, single-ASIC Bitcoin solo miner that anyone can build or buy. Running a single Bitmain BM1370 chip (the same class found in modern industrial miners), it produces roughly 1.2 TH/s while sipping only around 15-21 watts, giving it the best efficiency in the Bitaxe line. It's fully open-source in both hardware and firmware, so you can inspect, modify, and repair it.

Be clear-eyed about the economics: solo mining against a network measured in hundreds of exahashes per second means the odds of your little device finding a block are extraordinarily low. A Bitaxe Gamma is best understood as a lottery ticket, a learning tool, and a conversation piece — not an investment. When you point it at a solo pool, you're buying a tiny, real chance to win a full block reward, and the honest expected value over any reasonable timeframe is essentially a rounding error. People buy them to learn how mining works, to support decentralization in a small way, and for the thrill of the long-shot chance.

What makes the Gamma genuinely good is that it delivers this experience quietly, efficiently, and openly. It runs cool enough to sit on a desk, is nearly silent, and the open-source AxeOS web interface is a great way to actually understand hashrate, difficulty, and pool mechanics. As a gift, a teaching device, or a hobby, it's the best-in-class pick — as long as you buy it understanding the odds.
