What's the difference?
In plain words, from the specs and your setup.
Your setup
Live rates · every result on this page is an estimate.
The country buttons set a typical household price; change it to your own.
Currency
€1 = $1.08 = £0.86. Mining pays in USD, so we convert USD → EUR first.
±50 % around today's live price.
Pool fee
Most pools keep 1–3 % of what you mine.
Fewer hours = less power and less income.
What each miner earns at your price
Net result after the pool fee and electricity, at today's network difficulty. Check the break-even price first: below it, the miner pays for its own power.
When does it pay for itself?
Cumulative result over 24 months. Each line starts at minus the price and marks the month it crosses zero.
Solo mining: the Bitcoin lottery
Many Bitaxe and NerdQaxe owners solo-mine on CKPool: tiny odds, but a hit pays the whole block to you.
Will it fit your home?
Socket, circuit, noise, heat, network and size, each read straight from the specs.
Circuit = one 16 A × 230 V household circuit (3,680 W); keep continuous loads under 80 %. Heat: BTU/h = W × 3.412; area assumes about 70 W of winter heat loss per m² (typical EU home, varies with insulation).
How loud is it?
Each miner on a decibel ruler with everyday sounds. +10 dB sounds about twice as loud.
True-to-scale sizes
Drawn from the listed dimensions on a centimetre grid.
Value for money
Price against hashrate for the miners on our compare pages (log scales). Bubble size = power draw. Up and to the left = more hashrate per euro.
Full specs
Clean units from the product data. The best value in each row gets a green tint and a trophy; ties get none.
