A solo Bitcoin miner using CKPool’s solo service found block 943,411 on Thursday and collected roughly $210,000, receiving 3.139 BTC in subsidy and transaction fees, according to block explorer mempool.space.
Solo mining has become rare. Bennet’s solo-block tracker shows solo pools discovered just 20 Bitcoin blocks over the past 12 months, totaling 62.96 BTC — about one solo win every 18.7 days on average. The longest dry spell between solo wins was 58 days; the previous solo discovery came on Feb. 28.
The payout arrives amid heightened competition across the mining network. Network difficulty, which measures how hard it is to find a block, recently registered its steepest adjustment since February, dropping roughly 7.7% before rebounding about 3.87% within 24 hours. Those swings reflect a temporarily weaker hashrate and briefly improved odds for miners, but overall difficulty remains near historic highs, so an individual solo miner’s chance of success is still extremely small.
Difficulty has climbed by orders of magnitude over the past decade, punctuated only by short-lived declines when operators power down unprofitable machines or repurpose rigs for other workloads such as artificial intelligence. As difficulty and input costs rise, the economics of mining increasingly favor large, well-capitalized operations over hobbyists.
Publicly listed miners are responding by reshaping balance sheets and fleet strategies rather than relying on one-off luck. Riot Platforms, for example, sold 3,778 BTC during the first quarter of 2026, joining other firms that have recently liquidated Bitcoin holdings, including MARA Holdings, Genius Group and Nakamoto Holdings.
Against that institutional backdrop, the CKPool solo win is a reminder that individuals can still occasionally beat the odds. The publisher encouraged readers to verify information independently and consult its editorial policy for more details.
