Every mining calculator answers "how much will I earn". I wanted the two numbers that
actually decide anything, so I built this as a Proof of Work oracle instead: what it costs
the network to produce one
BTCTC, and what your real odds are of finding a block.

https://backpow.com/BitcoinThe odds are a Poisson process on live difficulty, so the page also draws the cumulative
probability curve over time instead of giving you a single average that hides the variance.
The hardware side currently holds 189 SHA-256 machines, from a NerdMiner up to a 20 kW
Whatsminer.
What it reports today:
- Network hashrate 919 EH/s, average block 9.9 min
- Block reward 3.125 BTC, so a block is worth about $245,900 at spot
- Cost of Production about $47,370 per BTC
- Spot is around $78,700, so production cost sits at 60% of price. Over the last 30 days
that floor moved only between $46,536 and $47,310
On the cost of production: I compute it with the most efficient ASIC on the network
(Bitdeer Sealminer A4 Ultra Hydro) at $0.069/kWh, because what I am after is the floor,
the cheapest(or close to) price at which anyone can still produce a coin. That is a choice, not a
truth, so the page lets you put in your own hashrate, wattage and electricity rate and
recomputes everything for your case.
The production cost is the part I could not find anywhere else. It is the electricity
floor under the price: when spot approaches it, the marginal miner is the one who stops.
Solo odds and daily economics(w pool mining) at $0.069/kWh, across the range:
- Bitaxe Gamma, 1.10 TH/s, 18 W: 1 in 15,819 per year, +$0.01/day.
Breakeven electricity $0.099/kWh
- NerdOctaxe, 9.61 TH/s, 150 W: 1 in 1,806 per year, +$0.12/day
- Antminer S19J 90T, 90 TH/s, 3250 W: 1 in 193 per year, but -$1.89/day.
Old gear is underwater at this rate before it is unlucky
- Antminer S21 Pro, 235 TH/s, 3510 W: 1 in 75 per year, +$3.28/day
- Whatsminer M79S, 1354 TH/s, 20 kW: 1 in 13 per year, +$19.38/day
