Source. Monthly production report, Bitmain Antminer S21 Pro 234 TH/s, Andes SolarHash, March to July 2026. Network difficulty as stated in the same report.
The miner delivered between 89.4% and 93.9% of the theoretical output, depending on the month.

The theoretical figure is what the network pays 234 TH/s running 24 hours a day, at each day's difficulty. It counts the block subsidy only.
Why it is not 100%.
- The miner does not always run at its rated hashrate.Over the 153 days it averaged 222.8 TH/s, or 95.2% of the 234 rated. Some days were far lower: on 22 June 2026 it averaged 139.5 TH/s. Maintenance, temperature and outages explain those drops.
- The pool charges a fee.For each effective TH/s, the pool paid a median of 96.5% of the theoretical value. The theoretical figure on this page leaves out the transaction fees miners receive, so the pool's actual fee is somewhat larger than that gap.
How it was calculated, and what this record does not say.
- Theoretical output per TH/s per day is 86,400 seconds × 10¹² hashes × 3.125 BTC, divided by difficulty × 2³². At the difficulty of 29 September 2026 (132,757,073,449,487) that gives 47.35 sats per TH/s per day.
- It is a single machine. The record belongs to one 234 TH/s Antminer S21 Pro. It does not describe other models or other facilities.
- The measurement is Andes SolarHash's own and has not been audited by a third party. The totals on this page were recalculated from the daily entries.
- It is not a projection. Difficulty rose and fell during the period and will keep changing. Past output does not predict future output.
- Buyers do not depend on this report. Each buyer follows their own miner from the app of the pool they chose.
What this site does not promise.
Bitcoin mining is not fixed income. ASH does not promise profitability, minimum output or a payback period.
