Peter Schiff claims Michael Saylor is running out of cash.

Veteran gold bug and longtime Bitcoin critic Peter Schiff has taken another swing at MicroStrategy's Michael Saylor, claiming the executive is "running out of cash" and questioning what assets he will liquidate next to sustain the company's aggressive Bitcoin accumulation strategy.

Schiff's comment is the latest in a long-running public feud between the two figures, who represent opposing ends of the hard-money debate. Saylor has repeatedly leveraged equity offerings and convertible notes to fund BTC purchases, a strategy critics argue is structurally fragile if Bitcoin's price corrects sharply or capital markets tighten.

As of now, MicroStrategy has not responded publicly to Schiff's latest remarks.
