Waste heat replaces heating A miner in a living space heats it. Whatever gas or electricity you therefore do not buy counts against the power bill, but only in the months you would be heating anyway.

Household prices per Eurostat, 2. Halbjahr 2025, including all taxes and levies. Your own tariff may differ considerably; cheap switching offers often sit ten cents below. Just type yours in.

The break-even electricity price is the price per kilowatt-hour at which earnings exactly cover the power bill. Below it the machine earns, above it the machine burns money. In central Europe that is the number almost everything turns on.

The sum behind it

Earned per day–

Earned per day in euro–

Power used per day–

Power cost per day–

of which heat credit–

BTC per day = hashrate ÷ network hashrate × 144 blocks × 3.125 BTC × (1 − pool fee) Power cost = watts ÷ 1000 × 24 h × price per kWh Break-even = earnings in euro ÷ kilowatt-hours per day

Not included: connection, cooling, power-supply losses, downtime and maintenance. Water cooling adds the loop itself, hosting adds the slot fee. Network difficulty rises over the long run, which lowers earnings at the same hashrate; the payback figure uses today's values and is therefore on the optimistic side.

Assessment

The Auradine Teraflux AH3880 is one of the best sums in the whole catalogue: 600 TH/s at 13.5 J/TH, and at the lowest price per terahash among the efficient water-cooled machines. Auradine is a US manufacturer, which makes it interesting for buyers who would rather not rest their supply chain on China alone. The catch is availability in Europe, which is markedly worse than for Bitmain or MicroBT.

Do the sums before you buy

If you do not like the numbers, you are not alone: at household prices almost none of these machines pay off in central Europe. If you still want to understand how mining works economically, you can play it through in the Coinovo app, with the same models and the same formulas, but without hardware and without a power bill.
