Income is calculated at $0.08 per kWh, a 1% pool fee and 98% uptime. Your own tariff can be entered on the coin page or in the catalogue.
What this rig is
NVIDIA RTX 3070 is GPU. It runs BEAMV3, ETCHASH, KAWPOW, KHEAVYHASH, NEXAPOW, OCTOPUS, ZHASH and draws 120 W: about 2.9 kWh a day and roughly 86 kWh a month. Multiply that by your tariff and you get the power bill that arrives regardless of what the coin is worth.
A GPU loses to an ASIC on speed but wins on flexibility: it runs several algorithms, survives the death of a single coin and sells not only to miners but to anyone who needs a graphics card. That is exactly why its payback is more honest when residual value is counted in.
Before you buy
- ·Wiring and sockets. A multi-kilowatt machine is not something you plug into an extension cord: it needs its own line, and in an apartment block also the agreement of whoever pays the shared meter.
- ·Noise and heat. An industrial ASIC means 70–80 decibels around the clock and kilowatts of heat that have to go somewhere. Home-friendly options — hydro versions and sound-proof enclosures — cost more and need space.
- ·Used units and warranty. The secondary market is tens of percent cheaper than new, but the machine already has hours behind it: ask where it stood and count payback with a margin for repairs.
- ·Pool and withdrawal. Income arrives through a pool: it has its own fee, payout threshold and schedule. Before buying, check that the coin has live pools and which exchanges you can withdraw to.
- ·The date of the calculation. The numbers here are live, but they describe today. Network difficulty almost always grows — assume the real payback will be longer than shown.
