How Long Does It Take to Mine 1 Bitcoin?
Quick answer: with a single modern ASIC (Antminer S21 Pro, 234 TH/s) you would need about 22 years to accumulate 1 BTC at August 2026 difficulty. Nobody actually mines "a whole Bitcoin" any more — miners earn a predictable trickle of satoshis per day through a pool, and the meaningful question is whether that trickle is worth more than the electricity behind it. Here is the real arithmetic, machine by machine, plus the same calculation for Litecoin, Monero and other proof-of-work coins where one whole coin is still a realistic target.
Figures snapshot: all numbers below are computed from live network data on 16 August 2026 — Bitcoin at ~$63,000, network hashrate ~860 EH/s, block reward 3.125 BTC (450 BTC issued per day). Difficulty moves every two weeks, so treat these as a calibrated reference and use the Bitcoin mining calculator for today's exact values.
The Math: Your Share of 450 BTC per Day
Bitcoin issuance is fixed: 144 blocks per day × 3.125 BTC = 450 BTC per day for the entire world, regardless of how many machines are mining. Your expected share is simply your hashrate divided by the network's:
BTC/day = (your hashrate ÷ network hashrate) × 450
For an Antminer S21 Pro pushing 234 TH/s against a ~860 EH/s network:
234×10¹² ÷ 860×10¹⁸ × 450 ≈ 0.000122 BTC/day → 1 ÷ 0.000122 ≈ 8,170 days ≈ 22.4 years
That 0.000122 BTC (~12,200 satoshis) was worth about $7.72 per day at the snapshot price — which is why miners think in dollars per day, not years per coin.
Time to 1 BTC by Hardware (August 2026)
| Setup | Hashrate | BTC per day | Time to 1 BTC |
|---|---|---|---|
| Antminer S21 XP Hyd | 473 TH/s | 0.000247 | ~11.1 years |
| Antminer S21 XP | 270 TH/s | 0.000141 | ~19.4 years |
| Antminer S21 Pro | 234 TH/s | 0.000122 | ~22.4 years |
| Antminer S19 XP (2022 gen) | 140 TH/s | 0.000073 | ~37.4 years |
| Bitaxe (USB open-source miner) | 1.2 TH/s | 0.0000006 | ~4,400 years |
| Small farm — 10 × S21 Pro | 2.34 PH/s | 0.00122 | ~2.2 years |
| Industrial site — 1 EH/s | 1 EH/s | 0.523 | ~1.9 days |
Every entry scales linearly: double the hashrate, halve the wait. That linearity is also why "how long to mine 1 BTC" has no single answer — it is entirely a function of how much hardware you point at the network. Browse efficiency specs for each machine on the mining hardware page.
Solo Mining: Same Average, Wildly Different Experience
The table above assumes pool mining, where you are paid your proportional share continuously. Mining solo does not speed anything up — it repackages the same expected value as a lottery. A lone S21 Pro finds a block on average once every ~70 years; when it does, it collects the full 3.125 BTC reward at once. Most solo miners will simply never hit a block, a few get lucky early — the expected value is identical, the variance is enormous. Our mining pools guide covers how pools smooth this out and what PPS vs PPLNS payouts mean for you.
What Mining 1 BTC Costs in Electricity
Time is only half the story — the power bill is the other half. An S21 Pro draws ~3,510 W around the clock. Over the ~22 years it needs to accumulate 1 BTC, that is roughly 690,000 kWh of electricity per coin (equivalently: ~84 kWh per day ÷ 0.000122 BTC per day). What that costs depends entirely on where you plug in:
- At $0.05/kWh (good industrial contract): ~$34,500 per BTC — profitable at a $63,000 price
- At $0.09/kWh: ~$62,000 per BTC — the approximate break-even point for this machine
- At $0.27/kWh (EU residential average): ~$186,000 per BTC — a guaranteed loss
This is why the answer to "should I mine Bitcoin?" is an electricity question before it is a hardware question. See where your country sits on the electricity cost by country table.
How Long to Mine 1 Coin of Anything Else
For lower-priced coins, one whole coin is a much shorter wait — which feels better but means nothing economically. One coin of each, with the typical hardware for its algorithm, at 16 August 2026 network conditions:
| Coin | Hardware | Coins per day | Time to 1 coin |
|---|---|---|---|
| Litecoin (LTC) | Antminer L9 · 16 GH/s | 0.044 | ~23 days |
| Dogecoin (DOGE) | Antminer L9 (merged with LTC) | ~177 | ~8 minutes |
| Monero (XMR) | Ryzen 9 CPU · ~20 kH/s | 0.0023 | ~14 months |
| Zcash (ZEC) | Antminer Z15 Pro · 840 kSol/s | 0.137 | ~7 days |
| Bitcoin Cash (BCH) | Antminer S21 Pro · 234 TH/s | 0.025 | ~40 days |
| Ethereum Classic (ETC) | High-end GPU · ~62 MH/s | 0.0053 | ~6 months |
| Ravencoin (RVN) | RTX 4090 · 62 MH/s | ~10 | ~2.4 hours |
| Kaspa (KAS) | IceRiver KS5 Pro · 21 TH/s | ~157 | ~9 minutes |
Notice the trap: mining 1 DOGE in eight minutes sounds spectacular until you remember one DOGE is worth seven cents. A coin's unit price is arbitrary — what matters is dollars of revenue per day versus dollars of electricity per day, which every calculator on this site computes for your exact hashrate and power rate.
Why "Time to One Coin" Is the Wrong Metric
Three reasons to drop it entirely once you understand it:
- It drifts constantly. Every difficulty adjustment changes the answer. The 22-year figure above was 18 years in early 2024 and will lengthen again after the 2028 halving cuts issuance to 225 BTC/day.
- It hides the cost side. A machine can be "only" 11 years from a coin and still lose money every single day if electricity costs more than the satoshis it earns.
- Fractions spend just fine. Bitcoin is divisible to eight decimal places; earning 12,000 satoshis a day at a profit beats "waiting for a whole coin" in every scenario.
The productive workflow: take your hardware's hashrate and power draw, your real electricity rate, and let the calculator tell you daily profit — then use the coin comparator to check whether your hardware earns more on a different coin, and the simulations to see how the picture changes across electricity tiers.
