Citi warns Bitcoin faces outsized quantum threat as computing advances

Citi has warned that Bitcoin faces an outsized threat from quantum computing as breakthroughs in the technology accelerate. The bank said the timeline for risks to crypto and broader internet infrastructure is being compressed, with Bitcoin seen as particularly exposed due to its reliance on elliptic curve cryptography.

For cryptocurrency traders, the quantum threat is a long-term structural risk that could undermine the security of Bitcoin's blockchain. If quantum computers become powerful enough to break the cryptographic keys that secure transactions, the entire network could be compromised. This has implications for the value proposition of Bitcoin as a store of value, as its security is a key pillar. While the timeline remains uncertain, the acceleration of quantum advances means the risk is no longer purely theoretical. Traders should monitor developments in quantum computing and any responses from the crypto community, such as potential protocol upgrades to quantum-resistant cryptography.

Looking ahead, the key events to watch include further announcements from major tech companies and research institutions on quantum milestones. The crypto community may also begin discussing quantum-resistant upgrades more seriously. Any concrete timeline for a quantum threat could trigger volatility in Bitcoin and other proof-of-work coins. Additionally, regulatory bodies may start assessing the systemic risk, which could influence policy. Traders should stay informed on both quantum computing breakthroughs and the crypto ecosystem's preparedness.
