Story: Citi Says Bitcoin Faces a Bigger Quantum Computing Threat Than Ethereum

Why Bitcoin's Governance Is the Problem. Bitcoin's decentralization is its whole pitch. No single entity controls it.

What This Means for Crypto Security Broadly. The quantum threat isn't unique to Bitcoin or Ethereum.

Citi just put out a warning. Bitcoin, the world's largest cryptocurrency by market cap, is more exposed to quantum computing risks than Ethereum — and the reason isn't purely…

The bank's analysis points to governance as the real dividing line. Bitcoin's decentralized model, famously resistant to top-down control, could slow down the network's ability…

Quantum computing isn't a tomorrow problem anymore.

The basic risk is well understood at this point. Modern blockchains rely on elliptic curve cryptography to secure wallets and validate transactions.

7 / 15

Bitcoin's decentralization is its whole pitch. No single entity controls it. Changes to the protocol require broad consensus across developers, miners, and node operators — a…

There's no official timeline from Bitcoin's developers on how they plan to address quantum threats. No detailed roadmap. No clear upgrade path.

Ethereum's governance, by contrast, has shown it can move. The network executed the Merge — one of the most complex protocol upgrades in crypto history — without breaking.

10 / 15

Citi's read is basically that Ethereum's flexibility gives it a meaningful edge. Faster consensus means faster implementation of quantum-resistant solutions.

The quantum threat isn't unique to Bitcoin or Ethereum. Every blockchain that relies on current cryptographic standards faces some version of this problem.

13 / 15

And Bitcoin's decentralization, which made it revolutionary, could be its weak point here. Prolonged decision-making processes have stalled Bitcoin upgrades before.

14 / 15

That's not to say it can't happen. But "can't happen" and "won't happen in time" are two different problems.

15 / 15

Ethereum holders probably aren't sleeping easy either. Quantum computing advancing faster than expected is a risk for the whole space.
