- A Solo CK Pool miner earned 3.151 BTC, worth $330K, on June 5, 2025.
- Block 899826 mined via Solo CK, the 300th on the platform.
A miner using the Solo CK Pool accomplished the extraordinary task of mining block 899826 on June 5, 2025. This was a remarkable occurrence. The reward given to the miner was 3.151 BTC and was worth $330,386 at the time of mining. While Bitcoin mining is a difficult thing to do independently, this achievement shows the potential upside of solo-style mining via platforms like Solo CK.
The total weight of this block is 3.99 MWU and the total size is 1.66 MB and it was mined at 04:48:18 UTC. The miner was also rewarded 0.026 BTC in transaction fees in addition to the block reward.
The Challenges of Solo Bitcoin Mining
Because it requires so much computing power, mining a Bitcoin block independently is an enormous accomplishment. According to information obtained from Blockchain.com, the hash rate of the Bitcoin network, which is a measurement of the overall computing power, reached 614 EH/s at the beginning of 2025

Solo CK Pool is the mining platform that enabled the successful miner to mine independently of large mining pools but still within a pool structure. This is a milestone for the service and Solo CK reported this as the 300th block mined through its platform.
The event took place on June 5, 2025, at 04:48:18 UTC, as the timestamp of the block shows. Block’s health was 100%, meaning that it had been successfully added to the Bitcoin blockchain without any problems.
Rewards and Significance of the Win
After Bitcoin’s halving schedule, the miner received a total subsidy of 3.125 BTC, the miner’s mining reward for mining a block in 2025. To this was added 3.151 BTC in fees, for a total of 0.026 BTC. At the mining time, this was about $330,386 at Bitcoin’s dollar value.
This win is more evidence of the draw of solo-style mining, in which miners receive the entire block reward themselves without splitting it with others, even though they are connected to a specialized pool like Solo CK. However, the process is highly competitive. The Bitcoin Wiki explains that the Bitcoin network generates new blocks on average every 10 minutes. There is a slim probability of success if a solo miner is competing against thousands of miners globally.
Solo CK Pool, the platform on which this win occurred, charges a service fee but allows miners to retain the full block reward. This structure appeals to those willing to deal with the high-risk, high-reward nature of solo-style mining.
The fee structure of the block had a median price of two Satoshis per vB, which is equal to $0.29 every transaction. This charge was placed inside the framework of the block’s system. In this low fee environment miner’s get more of the reward from the subsidy rather than from fees.
However, if this miner’s success is anything to go by, solo-style mining through pools like Solo CK is a challenge but not an impossible feat for those determined to take it on. The $330,386 payout is clear evidence of the financial upside that can result when you beat the odds.
