Citi: Ethereum Better Positioned Than Bitcoin to Survive Quantum Computing Threat by 2030!

A Citi analysis flagged in a widely circulated post warns that Bitcoin faces a steeper quantum computing risk than Ethereum by 2030 — and the core issue isn't cryptographic, it's governance. Ethereum's more agile upgrade mechanism gives it a credible path to adopting quantum-resistant cryptography before the threat materialises, while Bitcoin's conservative, consensus-heavy governance model makes rapid protocol changes structurally harder to execute.

The quantum threat to public-key cryptography is not imminent, but the 2030 horizon is close enough that institutional analysts are beginning to factor it into long-term positioning. Citi's framing puts the spotlight on Bitcoin's ability to coordinate a network-wide upgrade at speed — a question the community has debated for years without resolution.

For Ethereum holders, the read is constructive: the network's track record of executing…
