CleanSpark, BitFuFu, and Canaan See Month-on-Month Decline in Bitcoin Production for June, Despite Over 10% Drop in Mining Difficulty

According to Odaily, publicly listed bitcoin mining companies CleanSpark, BitFuFu, and Canaan have disclosed their June operational data, revealing that all three companies experienced a decline in bitcoin production compared to May. Specifically, CleanSpark mined 614 BTC in June, down from 671 BTC in May; BitFuFu mined 125 BTC, down from 177 BTC the previous month; and Canaan mined 64 BTC, down from 90 BTC in the prior month. CleanSpark’s average operational hashrate in June fell from 46 EH/s to approximately 43 EH/s; BitFuFu’s total hashrate dropped from 19.5 EH/s to 15 EH/s, while its proprietary hashrate rose to 3.5 EH/s. Canaan attributed part of the production decline to grid maintenance at some of its mining sites. This production downturn occurred after Bitcoin mining difficulty was reduced by over 10% in mid-June, reaching a new low for 2026.
