Michael Saylor, in an interview with Natalie Brunell, challenged the notion that assets must generate cash flow to hold value. He compared Bitcoin to widely accepted assets like diamonds, gold, and land, which also do not produce cash flow. Saylor emphasized that the key attributes of a currency are liquidity and marketability, not cash flow. He highlighted the irony of Vanguard's CEO labeling Bitcoin as "uninvestable," despite Vanguard being the largest shareholder in his company. Saylor argued that understanding Bitcoin requires focusing on its monetary essence and liquidity structure rather than cash flow metrics.
