Solo Miner Claims $376K Block Reward on 933 EH/s Network
A lone Bitcoin miner working through the Solo CK pool successfully mined block 907,283 on Saturday. This miner earned the full 3.125 BTC block reward worth $373,000 alongside $3,436 in transaction fees. Achieving this on a network with a hashrate nearing 933.61 exahash per second stands as an increasingly rare feat in today’s industrial-scale mining landscape.
Bitcoin’s mining difficulty recently hit a record high of 127.62 trillion on July 25, making it extremely challenging for solo miners to compete against corporate mining giants.
Pattern of Solo Miner Success in 2025
Despite these challenges, 2025 has already seen several notable wins by solo miners. Earlier this year, a solo miner earned $300,000 in February by solving block 883,181, and another earned $350,000 in July using just 2.3 petahashes of power. In June, a solo miner temporarily boosted their hashrate to 259 petahashes per second, likely via rented capacity, to solve block 899,826 worth $330,000.
Con Kolivas of CKpool estimates these victories happen roughly once every several years given the daily odds. These solo miner wins illustrate that despite being improbable, solo mining remains viable for those willing to persist.
Industrial Mining Faces Increasing Pressure
The broader mining industry is under pressure as rising operational costs and diminishing profits squeeze margins. In June, multiple Texas miners throttled energy use to dodge peak-hour tariffs, causing temporary dips in block production.
Major mining firms like Marathon Digital and Riot Platforms are diversifying into AI data centers and specialized computing to offset mining downturns.
In 2025 alone, Bitcoin’s difficulty surged by 32.24%, with a three-year cumulative increase over 410%. The next difficulty adjustment on August 7 may push this higher by another 6.83%, favoring industrial-scale miners with cheap energy and advanced hardware.
Despite these trends, the latest solo miner victory proves Bitcoin’s decentralized design still allows individuals to participate meaningfully.
