But we saved everything 🙂.

Cardone has addressed large asset movements in previous commentary. He recently highlighted Saylor’s sale of 32 BTC out of more than 843,000, noting the sale represented only a small fraction of total holdings. In a separate post, Cardone stated that the recent Bitcoin selloff driven by AI adoption was not tied to underlying business fundamentals.
