[Despite a more than 10% drop in mining difficulty, CleanSpark, BitFuFu, and Canaan's Bitcoin production in June still declined month-over-month] According to a report by Jinse Finance on July 15, operational data disclosed by publicly listed Bitcoin mining companies CleanSpark, BitFuFu, and Canaan showed that all three companies experienced a decline in Bitcoin production in June compared to May. Specifically, CleanSpark produced 614 BTC in June, down from 671 BTC in May; BitFuFu produced 125 BTC, down from 177 BTC the previous month; and Canaan produced 64 BTC, down from 90 BTC the previous month. The report noted that the reasons for the production decline varied among the three companies. CleanSpark's average operational hash rate in June dropped from 46 EH/s to approximately 43 EH/s; BitFuFu's total hash rate fell from 19.5 EH/s to 15 EH/s, primarily due to a decrease in hosted hash rate, although its self-owned hash rate increased to 3.5 EH/s; Canaan attributed part of its production decline to power grid maintenance at some mining facilities. It is worth noting that the production decline occurred after Bitcoin mining difficulty was adjusted downward by over 10% in mid-June, reaching its lowest level since 2026.
