# Solo Bitcoin mining odds: expected time is not a deadline A solo miner’s chance of finding a block is approximately its share of effective network hash rate under comparable operating conditions. Expected block counts describe an average across repeated possibilities; they do not schedule a win. A miner can find a block quickly or operate much longer than the expected wait without one. Network conditions, downtime and valid-block propagation also affect practical results.

Because one EH/s equals one million TH/s, the network rate is 1,000,000,000 TH/s. The miner’s share is one ten-millionth. At an assumed network average of 144 blocks per day, the expected count is 0.0000144 blocks per day. The reciprocal is about 69,444 days, or 190.3 years using 365 days per year, if every assumption stayed fixed. Evidence: [Bitcoin Mining Pools: 101](https://f2pool.io/mining/insights/20200318-mining-pools-101/) ## Expected waiting time is not a countdown Using a constant-rate Poisson approximation, that hypothetical miner has probability 1 − exp(−0.0000144) of at least one block in a day, approximately 0.00144%. The model assumes steady effective hash share and independent successful hash attempts. Waiting through an unsuccessful day does not make the next day owe the miner a block. The model’s expected wait can be long even though an early success remains possible.

A solo service may supply infrastructure while still leaving the miner exposed to solo reward variance. Do not project the illustrative 190-year average as a real forecast. Difficulty, network hash rate, equipment reliability and operating strategy change; a claimed lucky outcome is not evidence that everyone can reproduce it.

No. Under the constant-rate model, elapsed unsuccessful work does not create a scheduled future success. The expected value describes the distribution, not a deadline. Evidence: [Bitcoin: A Peer-to-Peer Electronic Cash System](https://bitcoin.org/bitcoin.pdf) ### Does a pool increase my machine’s physical hash rate? Joining a pool does not create additional calculations in the same hardware. It combines work and changes how rewards are shared and their variance.
