In the hyper-competitive world of bitcoin mining, where industrial-scale operations dominate, a lone miner has defied the odds. This August 2025, an independent miner using the Solo CK pool solved block #910,440, netting a staggering $365,000 in Bitcoin. This rare victory highlights the enduring allure—and immense risk—of solo mining in an era of corporate giants.

How Did a Solo Miner Beat the Odds?

Bitcoin mining has evolved from a hobbyist activity to a high-stakes industrial operation. What once could be done on a home computer now requires specialized hardware and massive energy consumption. Yet, against all odds, an independent miner using the Solo CK pool—a platform designed for solo miners—recently solved block #910,440. The reward? Approximately $365,000, comprising the standard 3.125 BTC block subsidy and an additional 0.012 BTC from transaction fees. The block contained 4,913 transactions, generating around $1,455 in fees.

Why Is This Victory So Rare?

Con Kolivas, the administrator of CKpool, noted that this was only the 305th solo block solved since the service’s inception. The miner was operating at roughly 9 petahashes per second (PH/s), giving them a daily chance of just 1 in 800 to solve a block. To put this in perspective, large mining farms operate at exahash levels (1,000 PH/s), making solo mining akin to winning the lottery. The Bitcoin network’s difficulty, currently at a staggering 129 trillion, further underscores the improbability of such a feat.

The Allure and Risk of Solo Mining

Solo mining offers a tantalizing prospect: keeping the entire block reward without sharing fees with a pool. However, the odds are astronomically low. For context, the same miner could have earned a steady income by joining a pool but chose the high-risk, high-reward path. This gamble paid off spectacularly, but it’s a reminder that for every success story, countless others mine for years without a single block.

Historical Context: Other Solo Mining Wins in 2025

This isn’t the first solo mining triumph this year. In February, another miner claimed the full 3.125 BTC reward. On July 4, a block worth 3.173 BTC (~$350,000) was solved, followed by another on July 27 worth ~$373,000. These wins, though rare, prove that solo miners aren’t entirely out of the game—yet.

What Does This Mean for the Future of Mining?

As mining difficulty rises and industrial players dominate, solo mining becomes increasingly quixotic. Large firms are now leveraging AI and high-performance computing to stay ahead, repurposing their infrastructure for other ventures. For the little guy, victories like this are a mix of inspiration and cautionary tale. As one Reddit user put it, “Solo mining is like playing the lottery—except the ticket costs thousands in hardware and electricity.”

FAQs About Solo Bitcoin Mining

How rare is solo mining success?

Extremely rare. The Solo CK pool has seen only 305 solo blocks since its creation, with odds often worse than 1 in 800 daily for individual miners.

What’s the biggest solo mining reward in 2025?

As of August 2025, the largest solo reward was ~$373,000 (3.173 BTC) on July 27.

Is solo mining profitable?

For most, no. The high upfront costs and low success probability make it a gamble. Pool mining offers steadier, albeit smaller, returns.
