Venture capital investor Tim Draper argues that the threat posed by quantum computing to Bitcoin is exaggerated. According to Draper, the real vulnerability in the near term lies not with cryptocurrencies, but with the traditional banking system and fiat currencies. The billionaire investor said he feels his Bitcoin holdings are safer than his dollar assets held in banks.
Shifting the quantum debate to banks
Draper suggests that quantum technology could target banking infrastructure long before it poses a problem for blockchains. He also notes that if a security issue were to arise on the Bitcoin network, the community could respond with a hard fork to revert to the last secure block. Of course, such a step would require strong consensus among miners and node operators.
Mini Glossary: A hard fork is a backward-incompatible change to a blockchain protocol. ECDSA-256 refers to the cryptographic method used for signature verification in Bitcoin; quantum risk in this context concerns the theoretical possibility of private keys being cracked.
Draper believes quantum systems will threaten banks long before they can reach blockchains, which is why he considers his Bitcoin safer than dollars in traditional banks.
His comments have once again sparked debate on Bitcoin’s resilience in the face of quantum computing developments. The discussion is particularly focused on public key security and how the network could react in emergency scenarios, with experts offering divergent views.
Draper’s Bitcoin journey and his long-standing projection
Tim Draper is one of Silicon Valley’s most prominent venture capitalists and has been a vocal proponent of Bitcoin for years. He began investing when Bitcoin traded at around $4, though hardware issues led to a delay in his mining activities until the price had already reached $30. Draper lost his entire Bitcoin stash during the infamous Mt. Gox collapse, but undeterred, he acquired about 30,000 Bitcoin for roughly $632 each in a 2014 U.S. Marshals auction.
Draper has long predicted that Bitcoin will overtake the U.S. dollar. He envisions a future where taxes are managed by smart contracts and companies hold their treasuries entirely in Bitcoin. His best-known prediction is that Bitcoin will reach $250,000.
Draper first made his $250,000 Bitcoin prediction in 2018, setting a 2022 timeline; he recently revised this target to 2025 and, as of early 2026, now believes Bitcoin could hit that mark within the next 18 months.
The original target was based on expectations of rapid price appreciation as mainstream adoption accelerated. However, the 2022 bear market and FTX’s collapse forced a reset of that timeline. Draper later attributed his adjusted outlook to the regulatory crackdown in the U.S., moving his forecast to 2025.
Ongoing technical debate on quantum risk
Despite Draper’s optimism, there is no industry consensus about how exposed Bitcoin is to quantum threats. A March 2026 Google Quantum AI paper estimates that breaking Bitcoin’s ECDSA-256 signature scheme could soon require fewer than 500,000 physical qubits—a twentyfold reduction compared to 2019 projections.
| Subject | Data |
|---|---|
| Draper’s current Bitcoin target | $250,000 |
| Timeframe for target | 18 months |
| Google Quantum AI threshold | Less than 500,000 physical qubits |
| Change since 2019 | 20 fold decrease |
Meanwhile, proposals like BIP 360—which seek to develop quantum-resistant address structures—are being discussed as part of the broader effort to strengthen the network’s long-term security.
