What one Antminer S21 XP would earn in a day at its rated 270 TH/s, in US dollars, before power and other costs.

Why use it. It turns the hash price into the revenue of a familiar machine, a quick read of mining profitability across cycles. How to read it. Higher means more revenue per machine-day. It assumes the machine runs at its rating all day with no downtime, and it is revenue only: subtract power to judge profit.

Calculation. Exact definition: Daily claimed-reward scenario for one S21 XP device at a nominal 270 TH/s, valued in USD at the admitted BTC/USD quote ending each UTC day. Higher values mean more USD reward per device-day, before any cost. It assumes the nominal rating for 24 hours at 100% uptime and is not an observed device fleet, measured payout, execution proceeds or actual miner profit. Day D is valued at the D+1 00:00 UTC quote; retrospective closes have unknown original publication clocks, and price revision guards are inherited. Earlier history applies the fixed rating retrospectively; USD history starts 2010-07-17. Open or unsealed days are unknown, and missing or non-positive quotes leave gaps. a × b when b is positive, otherwise undefined, where a is the S21 XP daily BTC scenario (daily BTC-per-EH/s claimed-reward normalization × 270 / 1,000,000) and b is the admitted BTC/USD quote at the day's ending D+1 midnight boundary. Boundaries before 2026-10-03 use admitted retrospective daily closing quotes; from then, the admitted prospective quote at or up to 15 minutes before the boundary, with no interpolation or carry.
