Concerns about the risk posed by quantum computing to Bitcoin's BTC $87,856.22 security have weighed on its market value and capital flows, according to crypto industry leaders.

Cypherpunk and Blockstream co‑founder Adam Back pointed out that the technology is still at a "ridiculously early" stage and said real threats are at least ten years away.

Even if some of Bitcoin's encryption were compromised, Back said its overall security does not depend on a single system.

Nic Carter, a partner at Castle Island Ventures, disagrees with developers who do not take quantum threats seriously.

Carter has described their attitude as "extremely bearish" and believes the lack of concern shown by developers is already affecting how investors value Bitcoin.

Craig Warmke of the Bitcoin Policy Institute explained that concerns about quantum technology have led some large investors to spread their money rather than put it all into Bitcoin.

Warmke criticized some technical voices for dismissing quantum fears by arguing that such dismissals only make investors more worried. He also said that many non-technical stakeholders misunderstand the conversation, which only makes the issue worse.

Both Carter and Warmke recommend making clear backup plans to ease investor concerns. Carter stressed that as companies and countries invest more in quantum research and artificial intelligence accelerates progress, it is even more important to be ready.
