A solo Bitcoin miner operating with a minimal amount of computing power has earned approximately $210,000 after successfully validating block 943,411 on April 2. The reward totaled 3.139 BTC and included both the standard block subsidy and transaction fees collected from that block. The miner’s hashrate stood at around 230 terahash per second, representing just 0.00002% of Bitcoin’s total estimated network hashrate of approximately 1 zettahash per second.
Bitcoin mining works by having participants race to solve complex cryptographic puzzles using computational power, with the winner earning the right to add a new block to the blockchain and claim the associated reward. What began as an activity accessible to individuals using standard computer processors has evolved into an industry dominated by large mining pools equipped with vast arrays of specialized ASIC hardware. Solo miners still participate, but their chances of winning any given block are extremely slim.
CKpool developer Con Kolivas noted on social media that a miner of this size faces roughly a 1-in-28,000 chance of finding a block on any given day. To illustrate the scale of the disparity, major industrial operations such as Riot Platforms run approximately 30 exahashes of hashrate — around 130,000 times greater than the solo miner’s output. Despite those odds, the miner succeeded in what Kolivas described as the 312th solo block solved through the platform.
The miner used solo.ckpool.org, an anonymous solo mining service that has been operating since 2014. The platform allows miners to retain their full block rewards, minus a 2% fee, without joining a traditional pooled mining arrangement. Its long-running history has made it a go-to option for individual miners attempting to compete against larger operations.
The solo miner’s windfall arrives at a time when large-scale Bitcoin mining companies are offloading significant portions of their holdings. Riot Platforms sold approximately $250 million worth of BTC last week, while MARA Holdings sold $1.1 billion in Bitcoin late last month. Both companies appear to be redirecting resources toward artificial intelligence infrastructure.
Solo mining victories, while rare, have occurred with some regularity in recent months. In December, a solo miner claimed a $282,000 block reward in a comparable outcome. That was followed in January by two separate miners each winning block rewards of roughly $300,000 within days of one another. In February, another miner earned $200,000 after spending just $75 renting hash power. These results suggest that while the odds remain long, solo miners continue to find occasional success against much larger competitors.
