A solo Bitcoin miner achieved a remarkable feat on Friday, netting 3.146 BTC, valued at approximately $266,000, after successfully solving block 924,569 using only a fraction of the computational power commonly required to win a block reward.
This miner operated with a hash rate of about 1.2 terahashes per second (TH/s), a minuscule figure in a landscape dominated by large-scale operations that produce exahashes (one quintillion hashes per second).
CKpool’s founder, Con Kolivas, took to X to celebrate the fortunate miner, emphasizing the rarity of such an event. He estimated that the odds of winning at the miner’s reported hash rate are approximately 1.2 million to one per day.
The miner received a total of 3.125 Bitcoin (BTC) from the block reward, along with an additional 0.021 BTC in transaction fees, culminating in slightly more than 3.146 BTC, as per onchain data.

More Wins for Solo Bitcoin Miners in 2025
Despite the dominance of industrial miners, the year 2025 has proven to be highly successful for independent miners. According to Mempool Space, 13 blocks mined independently through CKpool have been recorded this year, averaging just over one each month.
In the previous month, a solo miner earned a reward of $347,455 by independently solving block 920,440, accumulating 3.125 BTC along with transaction fees entirely by themselves.
This July, another miner with merely 2.3 petahashes of power secured a complete block reward. Earlier wins were also noted in June, March, and back in February.
Shift Towards AI Among Bitcoin Miners
Major mining operations are increasingly exploring new revenue opportunities beyond traditional Bitcoin mining, particularly following the recent halving that has compressed their profit margins.
CleanSpark has already initiated a pivot towards AI-centric data center infrastructure, seeing its stock surge by 13% following the announcement in October. Additionally, TeraWulf is planning to raise $500 million through a convertible note offering to support the construction of a new data center campus in Abernathy, Texas.
