Methodology

Miners are ranked by Efficiency (J/TH) (lowest 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.

All data comes from our ASIC Miner Database. Scores, specs, and profitability update automatically. Only miners meeting this page's filter criteria are shown.

Frequently Asked Questions

What is the best Bitcoin miner under $500?

It depends on your goals. For solo mining, the Bitaxe Supra offers the best experience. For used ASICs, refurbished S9s and S17s can be found under $500 with much higher hashrate.

Are cheap Bitcoin miners worth it?

Budget miners are worth it for learning, supporting network decentralization, and dual-purpose heating. They may not be the most profitable per dollar, but they provide real mining experience.

Can I mine Bitcoin for free with cheap hardware?

Mining always costs electricity. However, if you use the miner as a heater, you offset heating costs dollar-for-dollar. The net cost of mining can approach zero in cold climates.

Should I buy a used ASIC miner?

Used ASICs can be great value, but inspect carefully for damaged hashboards, fan issues, and firmware problems. D-Central offers ASIC repair services and sells tested refurbished units.

What ongoing costs should I budget for?

Electricity is the main ongoing cost. Budget for your local rate times 24/7 operation. Also consider replacement fans ($10-30 each) and occasional dust cleaning supplies.

How many miners qualify for this list, and which ranks first?

49 miners currently meet this page's criteria. The Bitaxe Gamma ranks first by efficiency (j/th). 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 350.0 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.
