The Bitcoin remarks land as BTC trades close to $60,500, down sharply from its late-2025 peak above $126,000. US spot Bitcoin ETF information outflows of $6.35 billion over 30 days by means of mid-June, reflecting cooling institutional demand.
Earlier, Coinbase CEO’s Bitcoin outlook has additionally flagged AI infrastructure prices as a variable reshaping crypto capital flows.
Grantham just isn’t alone in his skepticism. Peter Schiff has made comparable bearish arguments, contending that Bitcoin holds no intrinsic worth.
Whether or not Bitcoin’s present worth holds key assist in Q3 2026 will take a look at each camps. Grantham predicted the decline would come steadily, over years and even a long time, not suddenly.
