Can you buy hashpower for less BTC than it mines?

You pay for an order in satoshis. The hashrate you receive mines satoshis back. Either you end the day with more than you started with or you don't — and because both sides are denominated in BTC, no price forecast can change the answer.

Weighted by where volume actually traded, every 1 sat spent returns
sat
on every satoshi committed
And that is the friendly case. Matching runs highest-bid-first, so to actually secure delivery you bid toward the top of the book — where the return is ().

Profitability per order type

Each row is a real price quoted by the marketplace right now, measured against the same hashvalue.

Contracts and Solo packages are sold through the Braiins web interface and are not exposed by the public API, so they can't be priced live here. Their arithmetic is identical: divide hashvalue by the quoted price per EH/s per day. Above sat, the order loses BTC.

Every resting bid, against breakeven

Each dot is a live buy order, placed by what it returns: above the line it hands back more BTC than it cost, below the line it hands back less. Plotting return rather than price keeps the good direction up — price would have to run backwards down the axis to read the same way.

What sellers can actually sell

The buy side is what people are willing to pay. This is the other half: what sellers are offering, and how much of it finds a buyer.

Every PH/s that found a buyer sold below hashvalue — PH/s in total, against PH/s above the line. Above hashvalue, PH/s sits unsold: nobody buys hashrate that mines back less than it costs. Plenty goes unsold below the line too — buyers are choosy about how far below — but the ceiling is absolute, and it falls exactly where this dashboard computes it from network data alone.

Today's traded price against breakeven

Volume-weighted price per 5-minute bar. The marketplace only publishes the most recent ~8 hours of candles, so this is an intraday view, and the still-forming final bar is dropped — on partial volume its last print spikes and reads as a move that didn't happen.

Dashed line is hashvalue ( sat); shaded stretches are where buying hashpower cost more BTC than it produced. of bars traded above the line. Weighting by volume matters: the raw last print of each bar straddles hashvalue roughly half the time, which is noise from a single trade on a thin book, not a market that is periodically worth buying into.

Run the fleet, or buy the hashrate?

The fleet is × Antminer S21 Immersion at TH/s and W apiece — PH/s drawing kW at J/TH, on /kWh power.

Run the fleet

×
— power costs sat per EH/s/day

Buy the same hashrate

×
— market asks sat per EH/s/day

Producing hashrate costs % less than buying it. Same units on both sides, so the two are directly comparable.

Anything left of the dashed line produces BTC for less than it is worth.

How much headroom is there?

Breakeven power price

per kWh, vs contracted — power could rise % before mining stops paying

Breakeven BTC price

vs spot — BTC could fall % before mining stops paying

Breakeven uptime

if a fixed delivery is promised and curtailed hours are bought in at market, this much self-mining covers the blend

Curtailment

Delivered

PH/s at % uptime

Mined per day

Power per day

Project net

per day, % share — site makes
The line is straight, and that is the point. Curtailment removes hashrate and power in the same proportion, so cost per EH/s/day does not change with uptime — only the absolute dollars do. Curtailment scales the business down; it never makes it uncompetitive. The same cancellation applies to the / split: because mined BTC and the power bill split on the same ratio, the project's net is exactly its share of the site's net. The split decides how the pie is cut, never whether there is one.

Method

Hashvalue is computed from public network data, not from the marketplace being measured:

Network inputs

Network hashrate EH/s
Reward paid per day BTC
Subsidy per block BTC
Average fees per block BTC
Fees as share of reward%
