Solo mining:
your real odds of finding a block.

Enter your hash rate. 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 halving. Next halving ~2028.

FOR CONTEXT

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 hashrate 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 mempool.space/mining before quoting odds.
