What this does and does not account for

• It is not a bet on Bitcoin. Your hashrate does not change, so your revenue does not either. Both the cost and the saving are in dollars — this is one of the few GoMining decisions whose payback does not depend on the BTC price.
• Payback is the same at any farm size. Cost and saving both scale per TH, so 16 TH and 700 TH pay back on the same date. You cannot start small to test it.
• Resale value is not counted, so the payback is pessimistic. A more efficient miner sells for more per TH on the secondary market, which shortens the real payback by an amount we cannot yet measure. For the cheap bands it changes nothing; for the last three watts it may decide the question entirely.
• A paused farm changes the maths. GoMining pauses a farm that would mine at a loss, so above a certain W/TH it earns nothing instead of losing money — and pays no electricity while paused. For such a farm the upgrade does not cut a bill, it restores income, and the figures above only apply once it is running again.
• Inside one price band, the payback is flat. Cost and saving both scale with the number of steps, so stopping halfway through a band buys you nothing in return — it only spends less. If a band is worth entering, it is worth taking to its floor.
• Prices are the ones GoMining published on 28 August 2026, fixed in USD. They change only when GoMining reprices, and this table will not know until it is updated.
