Further assumptions
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.

Network hashrate 973 EH/s ·

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

At 27.5 J/TH the S19j Pro+ is the least efficient machine in this catalogue. Bought new, it makes no sense anywhere in central Europe today. It is listed because the second-hand market is full of them and they are regularly offered as apparent bargains. Check the break-even price above before you buy: it sits so low that almost nobody outside an industrial tariff reaches it.

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.
