Harvard economist Kenneth Rogoff, who once predicted Bitcoin would collapse to $100 rather than rise to $100,000, has acknowledged his error as Bitcoin now trades above $100K. He admitted underestimating Bitcoin’s resilience, particularly its entrenched role in the underground economy, which has sustained demand and provided a price floor. Rogoff argued regulators were too lax, failing to impose stricter rules when crypto adoption surged. He highlighted conflicts of interest, noting many regulators themselves hold significant crypto. While conceding misjudgments, Rogoff still warns that unchecked speculation and insufficient oversight could amplify risks within the global financial system.
