Harvard professor and ex imf chief economist offers excuses for misjudging bitcoin a decade ago

Overview

  • Rogoff acknowledged on X that his 2018 view—Bitcoin was more likely to sink to $100 than reach $100,000—was wrong, with the token now trading around $113,000 after highs near $124,000.
  • He said he was “far too optimistic” about the United States adopting what he called sensible crypto rules, pointing to recent measures such as the GENIUS Act and CLARITY Act.
  • The economist added that he underestimated Bitcoin’s use in the global underground economy and noted that top officials openly hold large crypto positions, referencing President Trump’s crypto ventures.
  • Crypto advocates including Anthony Pompliano and Saifedean Ammous criticized Rogoff’s explanation, and a Bitcoin Magazine op‑ed framed his post as a defensive rationalization.
  • Coverage recapped that Rogoff had cast Bitcoin as chiefly for illicit activity in 2018, a stance at odds with the market’s subsequent multiyear recovery to six‑figure prices.
