Bitcoin Cash solo mining calculator
Your solo odds on Bitcoin Cash
A Bitaxe Gamma (1.2 TH/s) solo mining Bitcoin Cash takes about 49 years, on average, to find one block at today’s difficulty of 429.81G.
Figures above are for a Bitaxe Gamma at 1.2 TH/s — enter your own hashrate or pick your gear to replace them.
The same 1.2 TH/s on Bitcoin: about 15,000 years · on DigiByte (SHA-256): about 27 days.
Bitcoin Cash network difficulty 429,808,256,146 at block 969,621, read from our own Bitcoin Cash node at . Bitcoin Cash retargets on every block, so the figure drifts through the day.
An average is not a countdown. Every hash is a fresh draw, so a block can land tomorrow or never, and the chance is the same for every block.
Which SHA-256 coin gives this device the best odds?
Of the three chains read just now, DigiByte’s SHA-256 algorithm has the lowest difficulty, so it gives every device the shortest wait: about 660 times shorter than on Bitcoin Cash and about 200,000 times shorter than on Bitcoin. The order is the same for every machine, because the wait depends on difficulty and hashrate alone; the device only sets how long each wait is.
| Device | Bitcoin | Bitcoin Cash | DigiByte (SHA-256) |
|---|---|---|---|
| Bitaxe Gamma1.2 TH/s | 15,000 years | 49 years | 27 days (the shortest wait) |
| NerdQAxe++4.8 TH/s | 3,800 years | 12 years | 6.7 days (the shortest wait) |
| Avalon Nano 3S6 TH/s | 3,000 years | 9.7 years | 5.4 days (the shortest wait) |
| Avalon Q90 TH/s | 200 years | 7.8 months | 8.6 hours (the shortest wait) |
| Antminer S21200 TH/s | 90 years | 3.5 months | 3.9 hours (the shortest wait) |
Average time to a block, at each chain’s difficulty as our own nodes reported it: Bitcoin 132.76T, read · Bitcoin Cash 429.81G, read · DigiByte 648.12M (recent SHA-256 average), read .
A block pays 3.125 BTC plus fees on Bitcoin, 3.125 BCH plus fees on Bitcoin Cash and about 250.75 DGB on DigiByte — coin amounts, not money. The coins are worth very different amounts, so this table compares odds and nothing else.
How the odds are worked out
Two lines of maths, the same on every SHA-256 chain. Blocks arrive as a Poisson process, so the wait is exponential rather than a countdown.
T = difficulty × 232 ÷ hashrate
P(at least one block in t) = 1 − e−t/T
T is the average number of seconds between your own blocks, because a block needs difficulty × 232 hashes on average; t is however long you mine.
Worked at the Bitcoin Cash difficulty above, for a Bitaxe Gamma at 1.2 TH/s:
T = 429,808,256,146 × 4,294,967,296 ÷ 1,200,000,000,000 ≈ 1.54 × 109 seconds ≈ 49 years
P(30 days) = 1 − e−2,592,000 / T ≈ 0.17% (1 in 590)
- Bitcoin Cash kept Bitcoin’s SHA-256 proof of work and its difficulty convention, so the formula carries over unchanged. It retargets on every block, so the difficulty drifts through the day; the time of each reading is printed beside it.
- Every hash is a fresh draw that remembers nothing. Time already spent mining does not bring a block closer, and a long dry spell does not make one more likely: the chance in the next 30 days is the same after a year of mining as after a minute.
- The pool does not change these odds. They depend only on your hashrate and the chain’s difficulty, identically on every pool; a pool changes the fee and who holds the reward, not the chance.
Quick answers
How long does it take to solo mine a Bitcoin Cash block?
On average T = difficulty x 2^32 / hashrate, in seconds. At the Bitcoin Cash difficulty our own node reported at 2026-09-22 10:33 UTC, a 1.2 TH/s Bitaxe Gamma takes about 49 years per block and a 200 TH/s Antminer S21 about 3.5 months. Every hash is a fresh draw, so a block can come far sooner than the average, or never.
What are my chances of finding a Bitcoin Cash block in a day?
P = 1 - e^(-86,400/T), where T is your average time to a block. At the Bitcoin Cash difficulty read at 2026-09-22 10:33 UTC, a 1.2 TH/s Bitaxe Gamma has a chance of 1 in 18,000 on any one day and 1 in 590 over 30 days. It is the same every day: a near miss yesterday does not raise today's chance.
Can a Bitaxe mine Bitcoin Cash?
Yes. Bitcoin Cash uses the same SHA-256 proof of work as Bitcoin, so a Bitaxe, a NerdQAxe or any Bitcoin ASIC mines it unchanged. Point it at a Bitcoin Cash pool and use your own Bitcoin Cash address, in CashAddr form, as the username.
Is Bitcoin Cash easier to solo mine than Bitcoin?
Its difficulty is about 310 times lower than Bitcoin's right now (both read from our own nodes, at 2026-09-22 10:33 UTC), so the same machine waits about 310 times less on average. The prize is 3.125 BCH plus fees instead of 3.125 BTC plus fees: far shorter odds, for a far smaller prize.
Solo mine Bitcoin Cash on SoloLuck
SoloLuck runs a true-solo Bitcoin Cash pool: 0% fee, finders keepers. A solved block pays its whole reward straight to your own address, and nobody holds your coins. It changes the fee and the custody, not your odds: those are the figures above, on any pool.
Use your own Bitcoin Cash address in CashAddr form, starting q or p, as the username. Never a Bitcoin address, or a legacy address starting 1 or 3: those formats look the same on both chains.
SoloLuck has not found a Bitcoin block. Its Bitcoin Cash pool has not found a block yet.
