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

Magic's Magic Miner BG01 delivers 4.5 TH/s at 120 watts, so 26.7 J/TH, which puts it in the bottom third: rank 114 of 126. An open board in this power class does not mine for yield; it plays solo against the entire network. The chance of a block is vanishing and the hit would be the full reward. A lottery ticket, not an investment. Its closest neighbours are the Nerdaxe Ultra at 26.0 J/TH above and the Antminer S19j Pro+ at 27.5 J/TH below. The gap upwards is 0.7 J/TH; whether the premium for it is worth paying depends entirely on your electricity price. We hold no market reference for this model, so the price field above stays empty. Enter your own quote and payback appears beside it. Net per day and break-even do not need a price anyway.
