Billionaire venture capitalist Tim Draper has dismissed concerns that quantum computers pose an immediate threat to Bitcoin (BTC), and argued that traditional banking systems are far more vulnerable. The longtime Bitcoin supporter said he considers his BTC holdings safer than the dollars sitting in his bank account. Draper also predicted that Bitcoin will eventually become more relevant than the U.S. dollar as adoption continues to expand.

Draper Says Quantum Threat Is Bigger for Banks

Specifically, in an X post on June 9, Draper referred to an earlier interview in which he was responding to questions about quantum computing.

He reiterated his argument that financial institutions would be targeted long before quantum machines become capable of threatening Bitcoin’s underlying infrastructure. As he said at the time:

“Quantum, etc., will hack the banks long before it can touch the blockchain.”

The billionaire investor went a step further, claiming that even if a major security incident affected Bitcoin, the network could recover through a rollback to a previously secure block. Such a move would require general consensus across the Bitcoin ecosystem and would likely only be considered in an extreme emergency.

Draper’s comments arrive amid growing discussion about the long-term impact of quantum computing on digital assets. Researchers have warned that sufficiently powerful fault-tolerant quantum computers could eventually derive private keys from exposed public keys, potentially putting some Bitcoin holdings at risk.

However, the timeline remains highly debated. Most experts believe practical attacks against Bitcoin remain years away, if not decades.

Debate Over Bitcoin’s Quantum Readiness Continues

Not everyone shares Draper’s view that banks face the larger challenge.

In late 2025, Casa Chief Security Officer Jameson Lopp warned that migrating Bitcoin to quantum-resistant cryptography could take years and require coordination across the network. Lopp estimated that public keys of around 4 million BTC are already out there, which makes them potential targets if a sufficiently advanced quantum computer ever came to the scene.

Lopp also argued that banks may be able to respond faster than decentralized networks because they can implement upgrades through centralized decision-making processes rather than requiring wide community consensus.

Despite those concerns, Draper remains bullish on Bitcoin’s future. He explained that he believes the cryptocurrency is currently progressing through its traditional four-year market cycle and expects new highs to emerge over time. As he said in the interview:

“It moves up before the halvings and usually reaches new highs. At some point, I expect Bitcoin to eclipse the dollar as the dollar becomes less relevant.”

The comments are consistent with the investor’s long-standing optimism toward Bitcoin. Draper has repeatedly forecast six-figure and even seven-figure BTC prices over the years and remains one of the most prominent venture capitalists backing the asset.

His remarks add another voice to the ongoing debate over whether quantum computing represents an existential threat to Bitcoin or simply another technological challenge the network will eventually adapt to.
