According to Deep Tide TechFlow, Nobel Prize-winning economist Paul Krugman stated in his blog that stablecoins have no significant useful functions and merely facilitate criminal activities, similar to 'pre-war banks' of the 19th century. He warned that stablecoins could evade regulation, posing a risk of financial crises.
Nic Carter, co-founder of Coin Metrics, refuted that Krugman's view is 'extremely incorrect', arguing that over 100 million stablecoin users worldwide demonstrate their practical utility. Paul Fusaro, president of Bitwise Asset Management, also supports Carter's perspective.
