Prominent cryptocurrency critic and gold advocate Peter Schiff has renewed his attacks on MicroStrategy Executive Chairman Michael Saylor, arguing that Saylor's most ambitious Bitcoin price predictions are falling apart under basic mathematical scrutiny.
Schiff specifically targeted Saylor's bold 2025 forecast that Bitcoin would reach $1 million per coin if Strategy succeeded in accumulating 5% of the total circulating supply. Strategy currently holds 3.9% of all Bitcoin in existence. However, Schiff contends that the law of diminishing returns is already severely undermining the firm's buying power and its ability to move the market.
"If buying the next 231,666 BTC has the same impact on Bitcoin's price as buying the last 231,666, Bitcoin will be below $60,000 when MSTR finally hits 5%," Schiff argued on X (formerly Twitter).
Schiff went further, alleging that U.S. financial regulators have been "bought and paid for with crypto money" as a way of explaining why authorities have not yet launched an investigation into Strategy's operations.
He also pointed to a stark shift in investor sentiment around the company's debt instruments. "In February 2021, Saylor raised money for $MSTR to buy Bitcoin by issuing 0% convertible senior notes. Investors wanted to participate in Bitcoin's upside by owning MSTR," Schiff noted. "Now he is forced to pay 11.5%, as investors don't want Bitcoin's limited upside. They just want the yield."
The Yield Debt Trap
Over the past week, Schiff has been sounding alarms that MicroStrategy is sliding into a dangerous financial "death spiral" driven by its growing dependence on high-yield preferred shares. He also pushed back against bullish arguments that Bitcoin only needs to appreciate by 2% annually to cover the cost of servicing that yield, pointing out that this assumption requires the company to stop issuing new debt.
"But Saylor is actually increasing issuance," Schiff warned. "The more STRC MSTR sells, the more BTC must rise to cover the yield."
Yet Another Massive Purchase
Saylor, for his part, appears entirely unmoved by the mounting warnings. Strategy recently acquired an additional 3,273 BTC for approximately $255 million, at a latest purchasing price of $77,906 per coin. The Virginia-based business intelligence firm now holds a total of 818,334 BTC on its balance sheet.
Why it matters
The shift in convertible note terms — from 0% interest in 2021 to 11.5% today — signals a measurable change in how debt markets are pricing Strategy's Bitcoin-backed financing, regardless of Bitcoin's current price level.
Schiff's core mathematical argument hinges on the law of diminishing returns: as Strategy's share of total supply grows, each additional purchase has less marginal price impact, which matters for evaluating whether accumulation targets can drive the price outcomes Saylor has projected.
The internal tension between issuing more yield-bearing instruments to fund purchases and needing Bitcoin appreciation to service that yield creates a feedback loop that investors in Strategy's preferred shares and convertible notes may want to model independently.
