Bitaxe Profitability — Bitcoin Mining
Is the Bitaxe profitable?
The open-source solo lottery miner — these figures model the Bitaxe Gamma (BM1370) at a stock ~1.2 TH/s, typical build (there is no manufacturer spec; Ultra and Supra builds run lower). Be clear about what it is: against a network above a zettahash (1,000+ EH/s), the expected wait for a solo block is measured in tens of thousands of years — the live odds are computed below. People run Bitaxes to hold a lottery ticket, decentralize block templates and learn the stack (ESP-Miner / AxeOS on GitHub), not for expected yield. The revenue figure below is the honest expected value of that ticket.
The only honest answer is a live one: revenue moves with the Bitcoin price and network hashrate every day. Nothing below changes the odds; it just prices the ticket honestly — expected value in sats, power cost in cents, lottery math in plain numbers. The break-even electricity figure is the line — pay less per kWh than that and the machine earns, pay more and it burns.

FAQ
- What does the revenue figure include?
- Block subsidy only — 144 blocks/day × 3.125 BTC at the live price, scaled by this rig's share of live network hashrate, after your pool fee and uptime. Transaction fees are excluded, so it is slightly conservative.
- What does the revenue figure exclude?
- Transaction fees, cooling power, and future difficulty growth — the payback figure assumes today's difficulty holds, which historically it does not. Treat payback as a floor.
