Major Bitcoin mining companies, holding over $8 billion in BTC, are accelerating their Bitcoin sales as prices have fallen more than 40% from the October high of approximately $126,000. Unlike previous downturns where sales primarily covered operational costs, proceeds from current sales are being redirected towards transitioning into AI data center businesses. MARA Holdings is considering selling part of its nearly $4 billion Bitcoin reserves as part of its new strategy. CleanSpark and Riot Platforms are advancing their AI transition through executive changes, while Bitdeer has completely liquidated its Bitcoin holdings.
