Quick answer
Best Bitcoin Miners for Solo Mining: D-Central ranks 15 qualifying miners by Hashrate, with the NerdOctaxe Gamma, NerdQAxe++ and Bitaxe Hex leading the current list. Live profitability, full specs, and the complete ranked table follow below.
Solo mining is the purest form of Bitcoin mining — you against the network, rolling the dice for a full 3.125 BTC block reward. These miners are solo-capable with built-in solo mining support. Ranked by hashrate because in solo mining, more hashes mean better odds.
D-Central’s pick for this list
The Bitaxe — silent, open-source solo mining from $184.99 CAD
A single-chip Bitmain ASIC (~1.2 TH/s, ~18W, near-silent) you can run on a desk. Open-source, repairable, and hand-built by D-Central in Canada — 2,600+ shipped since 2016.
15 miners in our database qualify for this list under the page's filter criteria. Efficiency spans 15.0 to 40.0 J/TH — the Bitaxe Gamma is the most power-efficient of the group. The quietest pick here is the NerdQAxe+ at 25 dB. At a $0.0735/kWh rate, the NerdQAxe++ posts the strongest daily profit at $0.01/day. For heat output, the NerdOctaxe Gamma tops the list at 682 BTU/hr — enough to heat ~25 sq ft.
Miners are ranked by Hashrate (highest first). Profitability is calculated server-side using live BTC price and network difficulty, with a default electricity rate of $0.0735/kWh (Quebec average). Daily revenue uses the standard formula: (hashrate x 10^12 x 86,400 x block_reward) / (difficulty x 2^32). You can adjust the electricity rate above to recalculate profitability for your location.

Frequently Asked Questions
What are the odds of solo mining a Bitcoin block?
It depends on your hashrate and network difficulty. A Bitaxe at 500 GH/s would take millions of years on average, but someone wins every 10 minutes. Use our Solo Mining Calculator for exact odds.
Has anyone actually solo mined a block with a small miner?
Yes — there are documented cases of solo miners finding blocks with relatively low hashrate. It is statistically unlikely but not impossible. Every hash has an equal chance.
What pool should I use for solo mining?
Popular solo mining pools include Solo CK Pool, public-pool.io, and Ocean. These are not traditional pools — they let you mine solo while handling the network connection.
Is solo mining a waste of electricity?
From a pure profit perspective, pool mining gives steadier returns. But solo mining contributes to network decentralization, and the heat still warms your home. It is Bitcoin mining in its purest form.
Can I solo mine with a Bitaxe?
Absolutely — the Bitaxe is designed for solo mining. Connect to a solo pool, enter your Bitcoin address, and start hashing. D-Central carries all Bitaxe variants with accessories.
How many miners qualify for this list, and which ranks first?
15 miners currently meet this page's criteria. The NerdOctaxe Gamma ranks first by hashrate. Rankings recompute automatically as our ASIC Miner Database is updated, so this list stays current.
How much does efficiency vary across these miners?
Efficiency on this list ranges from 15.0 J/TH to 40.0 J/TH. Lower J/TH means less electricity per unit of hashrate — at scale, that gap compounds into a meaningful difference in your monthly power bill.
