Solo Bitcoin Miner Earns $349,028 With 2.3 PH/s Hash Power

A solo Bitcoin miner made headlines on July 3, 2025, by successfully mining block 903,883, earning a substantial reward of approximately $349,028. This achievement was particularly noteworthy because the miner used only 2.3 petahashes per second (PH/s) of hash power, a fraction of the processing power typically required to compete in the Bitcoin mining landscape. The miner's success was facilitated through CKpool, a mining pool designed to support individual miners rather than large-scale operations.

The odds of such a win were staggeringly low, estimated at around 1 in 375,300, making this event a rare occurrence in the Bitcoin mining community. The reward for mining block 903,883 consisted of 3.173 BTC, which, at the time, was valued at approximately $108,400 per coin. This payout included the standard block reward of 3.125 BTC plus an additional 0.048 BTC in transaction fees, totaling 3.173 BTC.

This event highlights the decentralized nature of the Bitcoin network, where even small-scale miners can occasionally achieve significant rewards. The success of the solo miner in mining block 903,883 serves as a reminder that, despite the dominance of large mining operations, the network remains open to individual participants. This decentralization is a key aspect of the Bitcoin ecosystem, allowing for a more inclusive and diverse mining community.

The miner's achievement is reminiscent of previous solo mining successes. In June 2025, another miner solved block 899,826 and earned over $330,000 in reward. A few months earlier, in February 2025, block 883,181 was mined solo, producing an approximate $300,000 return. These events further demonstrate that although the chances are minimal, solo mining success is still possible.

The overall situation with cryptocurrencies is quite encouraging as well. This has been positively affected by the current adoption of digital assets, such as the policy trends, such as the Trump-friendly crypto bill. People are watching such trends as single victories and institutional changes that create reformation in the market.
