The shortest theoretical time to mine 1 Bitcoin is approximately 10 minutes, aligning with Bitcoin's block creation interval. When a miner successfully adds a new block to the blockchain, they receive a 6.25 BTC reward. However, individual miners typically earn fractions of Bitcoin by joining mining pools, which distribute rewards proportionally based on contributed computing power.
Factors Influencing Bitcoin Mining Time
1. Computing Power (Hashrate)
- Network Hashrate: The total computational power of the Bitcoin network determines mining difficulty. As of recent data, the network operates at ~368.5 EH/s (exahashes per second).
- Individual/Minipool Hashrate: To mine 1 BTC daily, you'd need ~420,000 TH/s (terahashes per second), equivalent to 3,500 Bitmain S19k Pro miners (120 TH/s each), costing ~$8.82 million upfront.
2. Mining Pool Participation
- Reward Consistency: Solo mining is impractical for most due to low success probability. Mining pools like Foundry USA (31.9% of recent blocks) offer steadier payouts by pooling resources.
- Pool Statistics: Foundry USA's 117.6 EH/s hashrate mined 275 BTC in 24 hours. Contributing 0.36% of this pool's power (~0.42 EH/s) could yield 1 BTC daily.
Realistic Timelines for Mining 1 Bitcoin
| Hardware Investment | Time to Mine 1 BTC | Notes |
|---|---|---|
| 1 Bitmain S19k Pro ($2,520) | ~3 years | 120 TH/s, excluding electricity |
| $25,200 in miners (10 units) | ~1 year | Assumes constant difficulty |
| $8.8 million (3,500 units) | 1 day | Professional-scale operation |

Challenges in Bitcoin Mining
Rising Competition
- Increasing Network Hashrate: Growth over the past 5 years raises mining difficulty.
- 2024 Halving Event: Block rewards will drop from 6.25 BTC to 3.125 BTC, slashing profitability.
Hardware Requirements
- ASIC Dominance: Consumer GPUs cannot compete with specialized miners like the S19k Pro.
- Economic Viability: Solo mining resembles a lottery; pools mitigate risk but require substantial investment.
Alternatives to Mining Bitcoin

- Running a Bitcoin Node: Supports network decentralization without mining.
- Direct Purchase: Often more cost-effective than mining for small-scale investors.
FAQs
How long does it take to mine 1 Bitcoin solo?
Theoretically 10 minutes, but probabilistically years for individual miners. Solo mining 1 BTC requires extraordinary luck due to high network difficulty.
How many Bitcoins remain unmined?
Approximately 1.54 million BTC (out of 21 million total supply) are left to mine as of 2024.
Can a gaming PC mine 1 Bitcoin?
Practically no. Even with 24/7 operation, a GPU miner would take decades due to insufficient hashrate (~0.000001% chance per block).
Is Bitcoin mining profitable in 2024?
For large-scale operations with low electricity costs, yes. Small miners likely operate at a loss after accounting for hardware and energy expenses.
Key Takeaways
- Bitcoin mining demands specialized hardware and massive energy inputs.
- Mining pools improve reward consistency but dilute individual payouts.
- Halving events and rising difficulty intensify competition over time.
- For most, buying Bitcoin outright proves more efficient than mining.
