MARA Holdings, a US-based Bitcoin mining firm and the second-largest public Bitcoin holder, now holds 52,850 Bitcoin worth over $6 billion, trailing only Strategy in corporate Bitcoin treasury holdings.

The milestone positions MARA as a key player in the growing trend of public companies adopting Bitcoin as a treasury reserve asset. MARA has emphasized its role in national digital economy infrastructure through both mining operations and strategic Bitcoin purchases.

Recent US Treasury guidance has clarified tax treatments for digital assets, benefiting Bitcoin holders like MARA by excluding certain unrealized gains from corporate minimum taxes.

MARA is pursuing sustainable energy initiatives, including wind-powered mining operations in Texas and Europe, to support its Bitcoin treasury growth strategy.
