Household electricity in Hungary costs 9.1 cents per kilowatt-hour. That is rank 1 of 27 in Europe. What it means for a mining machine is below.
At 9.1 cents, 41 of the 85 machines pay off. That puts Hungary among the few countries in Europe where mining works at all on an ordinary meter.

This figure is the pure electricity input needed to earn one whole bitcoin through the network, calculated with the most efficient machine in the comparison and the tariff above. Hardware, cooling, staff and downtime are not in it. If it sits above the bitcoin price, mining costs more than the result is worth.
Within Europe more than forty cents separate the cheapest household tariff from the dearest. That decides profit and loss far more sharply than any choice of machine. The neighbours by price:
Buy machines, grow hashpower, push power costs down. The same arithmetic as here, only without real money.
