A Solo Bitcoin Miner Defies the Odds: Mines Block 910,440 and Earns a $371,000 Reward
A solo Bitcoin miner has successfully mined block 910,440 through the Solo CK pool, earning a block reward of 3.137 BTC—approximately $371,000 at current market prices. This remarkable achievement stands out in today’s high-difficulty Bitcoin network and serves as a reminder of the crypto world’s blend of luck and skill.
The block included a total of 4,913 transactions, with accumulated transaction fees amounting to $1,455. While this figure is modest compared to the block reward, it highlights the ongoing activity and transaction frequency on the Bitcoin network.
Solo Mining: Probability and Challenges
Samuel Li, CTO of ASICKey, notes that for a solo miner with 1 petahash of hash rate, the odds of successfully mining a block within any given 10-minute window are only about 1 in 650,000. Even so, 2025 has already seen several instances of solo miners claiming block rewards, including notable successes in February and July.
Li emphasizes, “Despite modern mining rigs offering higher hash rates and lower energy consumption, solo mining still relies heavily on luck. Without tens of petahashes in play, long-term profitability is nearly impossible to predict.”
This perspective reveals the core reality of Bitcoin mining—a dual contest of hash power and luck. With network difficulty nearing an all-time high of 129 trillion, a solo miner finding a block is almost like winning the lottery.
Network Difficulty and Mining Industry Trends
As Bitcoin’s network difficulty continues to rise, professional mining companies are expanding into new areas such as artificial intelligence and high-performance computing to maintain profitability. For solo miners, while occasional “lucky strikes” do happen, joining a mining pool remains the key strategy for risk diversification and stable returns over the long term.
It’s also worth noting that modern mining rigs focus not just on hash rate, but on energy efficiency. Low-power, high-hash-rate devices are especially valuable when electricity costs are high. This is one reason why major mining firms invest heavily in developing proprietary ASIC chips.
Highlights for Solo Miners in 2025
Several successful solo mining cases this year have demonstrated that, even in a high-difficulty environment, a “fortunate few” can still claim substantial rewards. Solo mining is not only a technical challenge—it’s also a high-risk, high-reward digital lottery.
- February: A solo miner earned a block reward of 2.85 BTC
- July: Another miner received 3.02 BTC
- November: The latest success—block 910,440 with a reward of 3.137 BTC
These cases have inspired solo miners and sparked widespread discussion in the crypto community about mining strategies and network difficulty.
Takeaways for Miners
- Patience and luck go hand in hand: The key to solo mining success lies in sustained effort and understanding network fluctuations.
- Focus on efficiency and costs: Higher hash rates mean greater electricity and equipment depreciation costs, so managing expenses is crucial.
- Diversify risk: Even solo miners can reduce overall risk by joining mining pools or adopting multi-asset crypto strategies.
Conclusion
The solo miner’s success in mining block 910,440 is a vivid illustration of “low probability, high reward.” The $371,000 block reward is not just a symbol of wealth—it reflects the ongoing vitality of the Bitcoin network and the diverse ecosystem of miners.
Looking ahead, as network difficulty continues to climb and hash rate becomes more concentrated, whether solo miners can keep hitting “lucky streaks” will be a focal point for the entire Bitcoin community.
