Solo Bitcoin Miner With 70 TH/s Wins Full Block Against 1-in-100,000 Odds

A solo Bitcoin
BTCUSD
miner has beaten extraordinary odds to successfully mine a solo block. The miner earned roughly 3.128 BTC, worth about $222,000, including subsidy and transaction fees.Wu Blockchain reported that the Bitcoin miner was operating at an estimated hashrate of just 70 terahashes per second (TH/s). That hash power represented approximately 0.0000074% of Bitcoin’s total network hashrate, which sat at over 940 EH/s on April 9.
At that scale, the probability of mining a block on any given day is estimated at around 1 in 100,000, translating to a statistical expectation of roughly one successful block every 300 years.

For context, major publicly listed miners operate at tens of exahashes per second, dwarfing the 70 TH/s rig. Thus, that scale gap illustrates how improbable the outcome was.
Meanwhile, the rare win comes amid shifting mining conditions. Global Bitcoin hashrate declined to around 1,004 EH/s in the second quarter of 2026, down from approximately 1,066 EH/s in the previous quarter.
The drop has been largely attributed to weaker mining profitability, which has forced less efficient machines offline.
At the same time, the mining industry is undergoing a structural shift. Many operators are increasingly diversifying into artificial intelligence and high-performance computing workloads.
“Based on recent company announcements, listed miners could derive as much as 70% of their revenues from AI by the end of this year, up from roughly 30% today. What began as a marginal diversification strategy is increasingly becoming the core business,” CoinShares noted.
While such solo mining successes remain exceedingly rare, they serve as a reminder that Bitcoin’s decentralized design still allows for unexpected wins, even in an increasingly competitive space.
