Bitcoin Miner Solo CK Made $330k with Mining a Single Block

According to the crypto analyst Bitcoin Historian’s X post, a solo crypto miner known as ‘Solo CK’ has received 3.151 BTC in reward after mining the Bitcoin block 899,826 on June 5, 2025, at 4:48:18 a.m. UTC.

Using the CKpool, the individual made a 3.125 BTC, equivalent to $330k at the current Bitcoin price, which is down significantly from its earlier ATH milestone of $111.7k. Moreover, he paid nearly $2,761 (0.026 BTC) in transaction fees for mining this 1.66MB block.

Although it seems like a common practice, experts believe that a solo miner mining the entire block is equivalent to winning the lottery. This is because the individual has to compete with global mining platforms and farms with their own horsepower against the massive 600+ EH/s network hashrate.

Solo BTC Miner Winning Against Neighboring Block Validators

The solo miner mined the 899,826th block, carrying 3,680 transactions, whereas the large pools like Foundry USA mined the neighboring blocks 899,825 and 899,827. This win is more significant because the Bitcoin miner had a very low hashrate.

Comparison of the neighboring blocks is as follows:

Block Miner Fee Reward Transaction Avg Fee Rate
899827 Foundry USA 0.025 BTC 3,872 ~1 sat/vB
899826 Solo CK 0.026 BTC 3,680 ~2 sat/vB
899825 Foundry USA 0.015 BTC 1,902 ~1 sat/vB

Although this is a major win, the community remains skeptical of the win. Some call it a jackpot, while others doubt the miner’s computing power. Besides this, it’s not that of a rare event, as many such incidents have also been noted in the past, but it’s highly challenging and difficult.
