Bitcoin Developer Speaks Out: “The Reason for the Declines Isn’t Quantum! Look at Ethereum!”

Quantum risk in Bitcoin has recently resurfaced, with claims that quantum concerns are behind the recent declines.

However, a Bitcoin Core developer disagreed, saying that quantum computing fears were not behind the recent BTC drop.

Speaking on renowned journalist Laura Shin’s Unchained podcast, Bitcoin Core developer Matt Corallo stated that the recent drop in Bitcoin was not caused by quantum computing.

He added that he did not agree with the assessment that quantum risk was the reason for the current price drop.

He argued that if the threat stemming from quantum computing were the real reason, Ethereum should show a significant increase against Bitcoin.

“If this were true, Ethereum should have significantly increased in value relative to Bitcoin.”

While some Bitcoin users accuse blockchain developers of not moving fast enough to make the network resilient to quantum effects, the Ethereum Foundation states that it is taking measures to be prepared.

At this point, the Ethereum Foundation recently announced its 2026 roadmap. It stated its goals include faster transactions, smarter wallets, better cross-chain interoperability, and quantum-resilient security.

In response to these ideas, Corallo, while acknowledging that quantum computing could be a potential long-term risk, argued that market participants were overestimating quantum risk when searching for the reason behind short-term declines.
