According to a Feb. 5, 2026 Bloomberg interview, the Nobel laureate said Bitcoin lacks fundamentals and compared its age to the first iPhone, underscoring skepticism toward cryptocurrency (digital asset class) built on blockchain (distributed ledger technology).
In a Feb. 5, 2026 interview with Bloomberg, Nobel laureate Paul Krugman warned that cryptocurrency (digital asset class) built on blockchain (distributed ledger technology) faces a 'Fimbulwinter'—a metaphor for a severe, prolonged winter. He argued that Bitcoin lacks fundamentals and is not 'future tech,' adding it is merely younger than the first iPhone. The critique reflects a longstanding view that, without traditional valuation anchors such as cash flows or intrinsic value, Bitcoin’s pricing is driven largely by sentiment and adoption. His comments add to the ongoing debate over the durability of digital assets during market downturns.
