Expert Comment
“Congratulations to miner bc1q~9sj3… A miner of this size has about a 1 in 2,800 chance of solving a block every day, or once every 8 years on average.” – Dr. CK (@Solo_CK), Solo CK Admin
Winner’s Setup
Used Solo CK, a service enabling solo mining with a 2% fee (avoids cost of a high-end mining rig). This contrasts sharply with massive mining pools.
Context: Becoming Solo Harder
- Total Bitcoin network hash rate currently estimated at ~881 EH/s
- User’s hash rate represents just 0.00026% of network
- Industrialization of mining: Warehouses full of powerful ASIC machines dominate
- Solo mining odds ≈ lottery odds; most successful solos are one-off events
Modern Bitcoin mining favors large operations due to steadily increasing network difficulty. Most miners participate in pools to share rewards (like Foundry USA’s >300k BTC total rewards). Solo mining successes, particularly significant ones, are exceptionally uncommon.
