Mark Carney, who served as Governor of the Bank of England before his political career, has been quite critical of Bitcoin's fundamentals. According to his public statements, he raised serious concerns about BTC's viability as a value store, questioning whether it actually holds value effectively. Beyond that critique, he also highlighted efficiency problems—suggesting the network isn't as operationally efficient as advocates might claim.

That said, his skepticism on Bitcoin didn't extend to the broader blockchain technology. Carney acknowledged blockchain itself shows genuine promise, distinguishing between the asset class concerns and the underlying technological potential. His take reflects a common perspective among traditional finance figures: reservations about Bitcoin as an investment, but recognition that distributed ledger technology carries significant implications for the future.
