The story so far

Jeremy Grantham, a billionaire investor and representative of GMO, has dismissed Bitcoin as a 'useless, speculative mechanism.' Grantham claims the cryptocurrency has no practical use and expects it to quietly disappear over the coming years and decades. Coverage from CNBC, Decrypt, Bitcoin Magazine, and Mint emphasizes Grantham's view that the asset will fade into irrelevance, with Mint noting these comments coincide with Bitcoin slipping below $60,000.

Forbes has also addressed the prediction, suggesting the forecast has one significant problem. Future attention will likely focus on the validity of Grantham's claims as the asset interacts with the $60,000 price level and whether further critiques of the mechanism's practical utility emerge.
