Michael Saylor’s Strategy, the largest corporate holder of bitcoin, reported that it would register a $5.9 billion unrealized loss on its digital assets in the first quarter, as a result of the decline in the OG crypto currency — about 18% year to date — and the company’s adoption of new accounting rules that took effect at year-end. In an SEC filing, Strategy said it expects the loss on its bitcoin holdings will result in a net loss for the quarter that ended in March. That would be the company’s fifth straight quarterly loss.
