Could you please elaborate on who holds the title of the largest
Bitcoin miner in the United States? I'm curious to know which company or entity dominates this space and what sets them apart from their competitors. Additionally, I'm interested in understanding the scale of their operations, their mining facilities' locations, and any notable achievements or milestones they've reached in the field of Bitcoin mining. Lastly, I'd like to know if there's any significant competition or challenges they face in maintaining their leading position.
