Solo Mining: Unique Opportunities for Individuals
Despite the high competition from large players in the cryptocurrency market, instances of successful solo mining prove that even individual miners have a chance to earn substantial profits.
“The solo miner was able to mine a Bitcoin block and received a reward of 3.151 BTC (over $330,000 at the current exchange rate), according to mempool.space”.
The Solo CK pool supports such participants by providing them the opportunity to independently process blocks and receive the full reward.
Trends Among Large Companies: Growth and Challenges
At the same time, there is notable activity from large companies in the market. The Chinese company Cango, which was involved in auto financing last year, has fully transitioned to Bitcoin mining as of April 2025. In just two months, the company mined 954.5 BTC, valued at over $100 million at the time of writing. In April, Cango mined 470 BTC, and in May, another 484.5 BTC. This shift in focus was made possible after selling its auto sector in China for $352 million. Overall, since the beginning of the year, Cango has already received 1541 BTC.
American MARA Holdings also set a record: in May, the company mined 950 BTC, which is 35% more than in the previous month. MARA processed 282 blocks — the highest result since the halving. The average daily production was 30.7 BTC. Meanwhile, MARA did not sell any Bitcoin, accumulating reserves of 49,179 BTC.
However, April marked a month of record Bitcoin sales for public miners since the end of 2022. According to TheMinerMag, they sold 115% of all mined Bitcoin, which is related to a decrease in mining profitability: the price per 1 PH/s fell to $55.
Operational successes do not always correlate with financial results. In the first quarter of 2025, MARA Holdings and Hut 8 reported losses of $533 million and $134 million, respectively. The reasons were changes in cryptocurrency accounting rules and a 60% drop in revenues. Riot Platforms, despite doubling its revenue, ended the quarter with a loss of $296.4 million but continues to actively develop its artificial intelligence segment.
