On July 3, 2025, a solo miner with a computing power of about 2.3 PH/s successfully found block number 903,883 in the Bitcoin network. For this, he received a payout of 3.173 BTC, which at the exchange rate of that time was about $340,000. This block included 3949 transactions, and the processing was carried out by the Solo CK Pool.
CKPool analyst Con Kolivas explained that the probability that a miner with such a hashrate will find a block in one day is about 1 in 2800. Thus, on average, such an event occurs only once every eight years for this equipment. However, successful solo mining is not uncommon: for example, in June 2025, another solo miner mined a block and received about 3.151 BTC in reward.
Also in March 2025, a miner with a hashrate of 3.3 TH/s mined a block and received about 3.15 BTC — equivalent to about $244,500 at the time.
Despite the dominance of large mining pools, such examples show that individual miners with sufficiently powerful equipment still have a real chance of making a significant profit. Bitcoin mining remains an attractive activity, even for those working alone, although the probability of successfully mining a block is low and requires significant computing resources.
Overall, Bitcoin block mining is a key process that ensures the operation of the network and the security of transactions. The results of solo miners are a reminder that decentralization still remains, despite the growth of large mining centers and the emergence of new technologies.
Thus, the successful extraction of a block by an individual miner is a rare but important event that inspires many enthusiasts and emphasizes that unexpected successes are still possible in mining.
