What this machine earns at your electricity price
Further assumptions
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
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 Proto RIG puts 819 TH/s at 14 J/TH into a 3U slot and is among the cheapest machines here per terahash. Proto is a small manufacturer, which means two things: attractive terms and greater risk on support and spare parts. For a hall where an outage is survivable that can work out. As a single machine with no fallback, less so.

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.
