Key Takeaways:
- A solo miner with just 2.3 PH/s hash power mined Bitcoin block #903883, earning 3.173 BTC (~$349,028).
- The odds of a miner of this size solving a block are roughly 1 in 2,800 per day.
- The block was mined via Solo CK and included nearly 4,000 transactions across 1.57 MB.
A solo Bitcoin miner has achieved a remarkable feat by successfully mining block #903883 on July 4, 2025, using only 2.3 petahashes per second (PH/s) of hash power.
The miner, operating through Solo CK = a platform for individual miners = earned 3.173 BTC, worth approximately $349,028 at the time.
BREAKING: A SOLO MINER JUST MINED AN ENTIRE #BITCOIN BLOCK WORTH OVER $350,000

This included the 3.125 BTC block subsidy and 0.048 BTC in transaction fees.
Bitcoin historian Pete Rizzo highlighted the rarity of this event, estimating the odds at roughly 1 in 2,800 daily -or once every eight years – for a miner of this scale.
The block contained nearly 4,000 transactions and measured 1.57 MB in size.
While the miner’s exact hardware setup is unknown, it’s believed they used multiple older ASIC machines to reach their hash rate.
For comparison, smaller hobbyist miners operate at only a few terahashes per second, making such wins nearly impossible.
Typically, mining a block monthly would require 166,000 TH/s – far beyond the reach of most individuals.
This success story adds to a small but growing number of solo mining wins, showing that despite overwhelming odds and industrial-scale competition, solo miners can still occasionally strike gold with relatively modest setups.
