A solo Bitcoin miner experienced an extraordinary stroke of luck on Friday, successfully mining block 924,569 and earning a reward of 3.146 BTC, valued at approximately $266,000. This remarkable achievement was accomplished with a hash rate of only about 1.2 terahashes per second (TH/s), a minuscule fraction of the computational power typically required in the highly competitive industrial mining landscape.
The miner, believed to be utilizing a hobby-grade machine, defied the odds in an industry characterized by industrial-scale operations that generate exahashes (one quintillion hashes per second). Con Kolivas, the creator of CKpool, announced the improbable win on X, congratulating the "extremely lucky" miner and estimating the daily odds of such an event at the miner's reported hash rate to be around 1.2 million to one.
Onchain data confirms that the miner's total reward consisted of 3.125 Bitcoin (BTC) from the block subsidy, augmented by 0.021 BTC in transaction fees, bringing the grand total to just over 3.146 BTC.
Increased Solo Mining Success in 2025
Despite the dominance of industrial mining operations, 2025 has proven to be a significant year for solo Bitcoin miners. According to Mempool Space, 13 solo-mined blocks have been discovered through CKpool this year, averaging slightly more than one per month.
This recent win follows a trend of solo mining successes. In the previous month, a solo Bitcoin miner secured a reward of $347,455 by independently solving block 920,440, earning 3.125 BTC plus fees entirely on their own. Earlier in July, another miner with a hash rate of just 2.3 petahashes claimed a full block reward. Similar victories for solo miners were also recorded in June, March, and February of this year.
Bitcoin Miners Explore AI Opportunities
In response to tightening margins following the latest halving event, major Bitcoin miners are actively seeking new revenue streams beyond traditional mining operations.
CleanSpark has already initiated a strategic pivot towards AI-focused data center infrastructure. This expansion reportedly led to a 13% surge in its stock price shortly after the initiative was first announced in October.
TeraWulf is also pursuing new ventures, planning to raise $500 million through a convertible note offering. These funds are intended to support the development of a new data center campus located in Abernathy, Texas.
