Grantham Slams Bitcoin as 'Useless' Amid Predictions of Gradual Decline

Billionaire investor Jeremy Grantham has called Bitcoin 'useless' and predicted it will eventually 'dwindle away… not with a bang, but a whimper', arguing that interest in the cryptocurrency will slowly fade rather than collapse overnight.

In an interview, Grantham said that Bitcoin's extreme volatility makes it an unreliable store of value. He pointed to its roughly 52% decline from its October 2025 all-time high of $126,080, and noted that gold delivered solid gains over the same period.

Grantham questioned Bitcoin's real-world utility, arguing that it has failed to become a widely used payment method. 'People don't use it to make serious trades, they don't use it to buy their dinner and pay at the supermarket,' he said.
