Solo Mine Bitcoin at Home for Less Than $3 a Month in Power.
The Gamma 601/602 is a compact, near-silent Bitcoin solo ASIC miner built around the same BM1370 chip found inside Bitmain's industrial Antminer S21 Pro — now in a palm-sized device that draws just 15–25W and runs whisper-quiet on your desk. It's the most accessible way to participate in Bitcoin mining without industrial hardware, high electricity bills, or noise complaints.

The Bitcoin Lottery — Your Monthly Ticket Costs $3
Solo mining is a lottery — your Gamma runs continuously, and every hash you generate has a chance of solving a Bitcoin block worth 3.125 BTC. The odds are long, but they're real: a solo Bitaxe miner found a full block in 2024. At just 15–25W, your monthly electricity cost is roughly $2–4 AUD. That's your ticket price for a chance at hundreds of thousands of dollars — every single month.

601 vs 602 — what's the difference?
Both the Gamma 601 and 602 use the identical BM1370 ASIC chip and deliver the same hashrate. The 602 is a refined PCB revision with improved component placement for marginally better thermal management and minor electrical optimisations. For most home miners, performance is identical — the 602 is simply the newer board revision.

AU Warranty via MinerHub |
Solo Bitcoin mining profitability depends on Bitcoin network difficulty, block reward, and luck. MinerHub does not guarantee any mining returns or block finds. The 1.8 TH/s figure represents overclocked performance — stock hashrate is approximately 1.2 TH/s at 17W. Overclocking may void manufacturer warranty and reduce hardware longevity. All figures are approximate.
