Sean Farrell, the Senior Vice President of Operations, stated that this is due to high network transaction fees and the availability of over 95% of the 5 EH/s self-mining capacity.

Bitcoin mining company Canaan is looking for new funding after experiencing a decline in revenue and profits. In its Q3 2023 earnings report, the company announced plans to sell $148 million in equity through an at-the-market offering. Canaan also recently agreed to issue up to 125,000 preferred stock at $1,000 each to an undisclosed institutional investor for a total of $125 million. The decline in revenue is attributed to a decrease in the number of Bitcoin mined and a fall in the number of ASIC mining rigs sold, as well as increased pricing competition and a softening in purchasing power. Canaan expects its Q4 revenue to remain unchanged due to challenging market conditions.

The aim was to lobby US lawmakers to eliminate environmental "misconceptions", steer policy narratives away from negative environmental claims, and see mining as beneficial to the economy and security. Perianne Boring, CEO of the Chamber of Digital Commerce, said: "The core message we conveyed to congressional offices today is that bitcoin mining is helping to achieve and advance US energy security and national security."
