Highlights
- A Bitcoin miner 'Solo CK' mined the 899826th BTC block, earning $330k in rewards.
- The individual made 3.151 BTC by mining this block and spent 0.026 BTC in transaction fees.

Collective traders or organizations now dominate the Bitcoin mining industry, but a few solo miners like CK end up defying the odds at times, winning against these groups. A Solo BTC miner, CK, recently succeeded in mining the 899,826th block and made nearly $330K in one such event. How? Let’s discuss.
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.
