Solo miners still have chances for significant profits

Industry dynamics: major players and financial results
The Chinese company Cango, which recently shifted its focus from auto lending to Bitcoin mining, is demonstrating rapid growth. By April 2025, the company began active mining and managed to extract 954.5 BTC in just two months — more than $100 million at the current exchange rate. In April, Cango mined 470 BTC, and in May another 484.5 BTC. The transition to mining became possible after selling its main business assets in China for $352 million. Overall, in 2025, the company has already mined 1541 BTC.
American MARA Holdings also set a record by mining 950 BTC in May — 35% more than in the previous month. The company managed to process 282 blocks, marking the best performance since the last halving. The average daily production was 30.7 BTC. MARA Holdings did not sell its Bitcoins, and currently, the company’s reserves amount to 49,179 BTC.
At the same time, in April, public miners sold a record volume of Bitcoins since the end of 2022 — 115% of all mined, which is explained by the decline in industry profitability: the price for 1 PH/s dropped to $55.
Financial reports for the first quarter of 2025 indicate a challenging situation in the industry. MARA Holdings reported losses of $533 million, while Hut 8 reported $134 million. MARA attributed its losses to changes in cryptocurrency accounting rules, while Hut 8 cited a 60% drop in revenues.
In contrast, Riot Platforms doubled its quarterly revenues but ended the reporting period with a net loss of $296.4 million. The company continues to develop its artificial intelligence segment despite financial losses.
