How soon could quantum computers threaten Bitcoin?
The exact timeline is uncertain, but several estimates suggest that sufficiently powerful quantum computers could emerge within 5-10 years, potentially making Bitcoin's encryption breakable. Citi's note accelerates the dialog around this mid-term risk.
What can Bitcoin do to mitigate quantum risk?
Bitcoin could adopt post-quantum cryptographic algorithms, but this would require a hard fork and consensus among developers and miners. Such upgrades are complex and not yet prioritized, leaving Bitcoin vulnerable in the medium term.
Should institutional investors sell Bitcoin because of quantum risk?
The Citi note is a warning, not an immediate sell signal. Institutional investors should monitor quantum developments and consider hedging by increasing exposure to quantum-resistant assets like Ethereum, but a wholesale exit is premature given the uncertain timeline.
