Canadian billionaire Frank Giustra has warned that Bitcoin (BTC) faces existential dangers from quantum computing and synthetic intelligence (AI).
In an X submit on March 8, the analyst mentioned the cryptocurrency can be lucky to outlive the following 5 years.
Giustra made the comment in response to a video clip that includes Block co-founder Jack Dorsey and Technique government chairman Michael Saylor.
Centuries? They are going to be fortunate to outlive AI and Quantum computing within the subsequent 5 years.

The clip, shared by Bitcoin infrastructure supplier Maestro, reveals Saylor emphasizing Bitcoin’s self-custody functionality, which he mentioned offers it moral and ethical superiority over most digital securities and helps projections that the community might endure for a century.
Dorsey echoed the view, highlighting Bitcoin’s gradual and predictable improve course of in contrast with faster-moving options like Ethereum (ETH), and expressing confidence that this strategy might permit it to perform as an internet-native foreign money serving billions for many years.
Notably, the 2 consultants agreed that the asset might hold rising in worth for hundreds of years.
Giustra dismissed the declare, saying centuries-long sturdiness is unrealistic given accelerating technological threats, and added that Bitcoin might be fortunate to outlive AI and quantum computing inside 5 years.
The mining financier and longtime gold advocate has incessantly criticized Bitcoin as a speculative asset slightly than a dependable retailer of worth, arguing its clear blockchain might make it extra weak to authorities seizure than bodily gold.
His foremost concern is quantum computing’s potential to undermine Bitcoin’s safety via algorithms comparable to Shor’s, which might derive personal keys from uncovered public keys and compromise elliptic curve–based mostly signatures.
Roughly 25% of Bitcoin’s provide, together with older or dormant addresses, could possibly be weak if sufficiently highly effective quantum computer systems emerge.
Progress in quantum computing
Current advances in quantum {hardware} have intensified the talk. As an illustration, firms comparable to Google, IBM, Quantinuum, and PsiQuantum have reported progress in qubit counts, gate constancy, and error-corrected techniques, whereas PsiQuantum has accelerated building of large-scale services.
Nevertheless, most consultants say a quantum laptop able to threatening Bitcoin stays years away. Some researchers, together with BIP-360 co-author Ethan Heilman, estimate Bitcoin has about seven years to attain significant quantum resistance if upgrades start quickly, given the coordination and adoption required throughout the community.
Builders have already begun addressing the chance. As an illustration, in February 2026, BIP 360, titled Pay-to-Merkle-Root, was printed within the Bitcoin Enchancment Proposals repository for assessment.
The proposal introduces a brand new output kind that hides weak public keys, just like Taproot, whereas eradicating quantum-exposed keypath spends.
It has not been activated and would probably require further proposals and years of group consensus.
Business estimates, together with from Citi Institute, place the chance of widespread public-key breakage at 19% to 34% by 2034, rising additional by 2044.
Most cybersecurity and blockchain consultants emphasize preparation slightly than predicting imminent failure, whereas authorities plans, comparable to U.S. timelines to transition important infrastructure to quantum-safe techniques between 2030 and 2035, replicate related warning.
