Following a modest recovery in August, publicly traded mining firms CleanSpark and BitFuFu encountered a drop in Bitcoin output during September, whereas Canaan maintained a steady generation rate.
CleanSpark extracted 529 BTC throughout September, marking a decrease of nearly 11% compared to August’s 593 BTC. BitFuFu yielded 167 BTC, representing a 4% reduction from the 174 BTC achieved the month before, while Canaan generated 44 BTC, matching its exact August figure.
CleanSpark
At the close of September, CleanSpark possessed 13,530 BTC, dropping from the 13,703 BTC recorded at August’s finish. The company reported selling 2 BTC through spot market transactions alongside another 700 BTC via call option executions at a mean sale value of $72,928 per coin.
Furthermore, CleanSpark stated it will discontinue monthly mining updates in favor of transitioning toward quarterly financial reporting.
This shift aligns with its growing focus on expanding its data center operations. Last week, CleanSpark finalized a $2.276 billion senior secured note offering aimed at funding the development of its Sandersville, Georgia, data center campus, which is projected to yield roughly $6.6 billion in revenue.
CleanSpark stock CleanSpark, Inc. (CLSK) exchanges hands at $8.76 on Thursday, bringing its year-to-date losses to over 24%.
BitFuFu
BitFuFu’s September downturn occurred even though its proprietary mining output grew by over 11% to reach 98 BTC, up from August’s 88 BTC. Conversely, its cloud mining output fell by nearly 20%, shifting from 86 BTC down to 69 BTC.
The firm’s bitcoin reserves saw a minor bump, moving from 1,373 BTC up to 1,388 BTC.
Additionally, the enterprise revealed complications regarding its planned acquisition of an 80 MW bitcoin mining facility in Ethiopia, which arose from conflicts between the facility manager and local electricity providers. BitFuFu has already allocated $4.1 million into the arrangement and installed roughly 13,700 Bitmain Antminer S19 units at the location.
The organization is presently evaluating various alternatives, including completely walking away from the agreement to salvage a portion of its capital.
BitFuFu shares (FUFU) trade at $1.27 on Thursday, reflecting a year-to-date decline exceeding 54%.
Canaan
Canaan’s bitcoin production remained static at 44 BTC throughout September, thereby concluding a three-month sequence of continuous decreases.
The corporation’s bitcoin treasury climbed to 1,875 BTC, up from the 1,868 BTC held during August.
On Thursday, Canaan also disclosed that its 8 MW Nordic heating initiative has become fully operational, utilizing thermal energy from its hardware to warm approximately 2,800 residential homes. The company is additionally engaged in designing a comparable heat-recycling venture in Canada.
Shares of Canaan Canaan Inc. (CAN) are priced at $0.25 on Thursday, marking a year-to-date decrease of more than 68%.
