Solo Miner Wins $350K Block Reward Against 1-in-36,000 Odds

• A solo Bitcoin miner solved block 913,593, earning $350,000 in rewards.
• The miner's 200 TH/s represented just 0.00002% of Bitcoin’s global hashrate.

On September 8, 2025 (UTC), multiple sources, including The Block and CoinGape, reported that a solo Bitcoin miner achieved an extraordinary milestone by solving block 913,593. This miner, using only 200 terahashes per second (TH/s) of hashpower, earned a total reward of approximately $350,000. The reward comprised 3.125 BTC in block subsidy and approximately 0.004 BTC in transaction fees.

The miner utilized CKpool, a solo-mining software that allows individual miners to compete for block rewards without joining a collective mining pool. Despite the miner's minimal contribution of just 0.00002% to the Bitcoin network's hashrate, the achievement highlights the inherent lottery-like nature of Bitcoin mining. With the Bitcoin network operating at over one zetahash per second, the odds of a miner with 200 TH/s solving a block are estimated to be one in 36,000 each day.

This event demonstrates the increasing difficulty of mining given the immense computational power of the Bitcoin network. It also underscores the rarity of such occurrences, as a solo miner achieving this feat is statistically expected only once every 100 years. Most smaller miners typically join mining pools to secure more consistent income, making this success an exceptional outlier in the ecosystem.

As of September 8, 2025, 17:09 UTC, Bitcoin (BTC) is trading at $112,264.64, with a 0.97% increase in 24-hour trading volume, according to CoinMarketCap.
