Solo mining:
your real odds of finding a block.
Enter your hash ratehash rateA measure of how much computing power the world is putting into running Bitcoin. The higher this number, the harder and more expensive it would be for any attacker to overpower the network.Full definition. See your honest probability of winning the block-reward lottery per day, per year, and over a lifetime. The math is exactly like a lottery, except the odds don't change.
Default: 6.59 TH/s (roughly 4x Bitaxe Gamma Duo).
Exahashes per second. 1 EH/s = 1,000,000 TH/s.
3.125 BTC after the April 2024 halvinghalvingThe event every four years where Bitcoin's new supply per block is cut in half, slowing the rate of new Bitcoin entering circulation.Full definition. Next halving ~2028.
Think of this as a lottery ticket that never expires. Most solo miners never find a block. Some find one in their first week.
What this tool assumes
- Solo-mining probability of finding a block depends on your hashratehashrateThe total computational power a miner or the entire Bitcoin network applies to finding blocks, measured in hashes per second. More hashrate means more security but also more competition for block rewards.Full definition share of total network hashrate.
- Payout is lumpy; expected value is identical to pool mining minus pool fees.
Network hash rate changes daily. Verify current figure at mempoolmempoolThe waiting area for Bitcoin transactions that have been broadcast to the network but not yet confirmed in a block.Full definition.space/mining before quoting odds.
