Tiny Bitcoin Miner Hits Jackpot: Solves $349K Block Solo with 2.3 PH/s
In a stunning twist of blockchain luck, a solo Bitcoin miner operating with just 2.3 petahash per second (PH/s) of hash power has mined a full block—earning close to $350,000 in rewards. The block, numbered 903,883, was confirmed on July 3 through CKpool’s solo mining service.

Statistically, the odds of finding a block at that level of hash rate are about 1 in 375,000, making this an extraordinary win. According to CKpool developer Con Kolivas, such a miner typically lands one block every 8 years, or has a 1 in 2,800 chance each day.
The reward, totaling 3.173 BTC, was confirmed on Mempool.space, combining both the standard block subsidy and accumulated transaction fees.
While most miners rely on large-scale pools to earn small but steady rewards, solo miners like this take a riskier route for the full bounty. Despite the odds, this is the third such solo success in 2025—proving that even low-powered setups can hit big.
Bitcoin researcher Pete Rizzo commented on the miner’s remarkable win, calling it a case of “beating incredible odds.” It’s believed that the setup used older ASIC miners to reach the modest hash rate.
In a market dominated by massive mining operations, rare solo victories like these continue to inspire individuals willing to gamble on luck—and sometimes win big.
