Bitcoin’s long-term security is facing fresh scrutiny as senior financial leaders warn about the potential impact of quantum computing. The latest warning comes from UBS CEO Sergio Ermotti, who raised concerns at the World Economic Forum in Davos.
Ermotti said the effect of quantum computing on the safety of cryptocurrencies still needs to be proven. His comments place him alongside other high-profile figures, including Ray Dalio and BlackRock executives, who have also flagged the issue.
Christopher Wood of Jefferies recently removed Bitcoin from his long-term pension portfolio. He cited the growing risk that advanced quantum computers could weaken Bitcoin’s role as a reliable store of value.
At the center of the concern is Bitcoin’s encryption system. Today’s computers would take trillions of years to break it, but powerful quantum machines could do so much faster, potentially allowing attackers to steal coins from vulnerable wallets.
Some research suggests the risk could be significant. Studies referenced by industry analysts estimate that 20% to 50% of all Bitcoin could be exposed in a successful quantum attack, representing hundreds of billions of dollars.
Crypto investors say institutions are worried but mostly staying quiet. Many are waiting to see whether Bitcoin developers move quickly to upgrade the network before making public statements.
Developers remain divided on how urgent the threat is. While some push for rapid changes, others argue that the danger is still theoretical and years away.
For now, the debate continues. As quantum technology advances, pressure is building on Bitcoin’s developers to prove the network can adapt and remain secure over the long term.
