Most Bitcoin wallets remain safe as quantum risks stay distant, while developers actively build mitigation solutions.
Quantum computing risks are once again in focus as Bitcoin’s long-term security comes under review. While fears of broken encryption persist, new research suggests the threat is not immediate or evenly distributed. Most wallets remain secure, with risk tied to specific exposure conditions. At the same time, developers and industry participants are already working on solutions to address future vulnerabilities.
Limited Wallet Exposure Keeps Bitcoin Safe Despite Rising Quantum Concerns
Galaxy Digital research analyst Will Owens said quantum threats remain largely theoretical at present. In a report released Thursday, he explained that advanced quantum systems could derive private keys from public keys. Such a process could allow attackers to impersonate users, forge signatures, and steal coins.
However, Owens stressed that not all wallets face the same level of risk. Most Bitcoin wallets remain safe under current conditions. Exposure occurs only when public keys are visible on-chain. As such, this creates two main risk categories. These are wallets with already-exposed public keys and those that reveal public keys during transaction spending.

if there’s even a chance that’s true, the bitcoin community should work to prepare and mitigate

The debate around quantum computing and crypto security has persisted for years. Many in the community see it as a long-term inflection point. Advanced machines capable of breaking encryption could expose user data and compromise funds.
Still, critics argue that such technology remains decades away from real-world use. Traditional financial systems may also face similar threats to those faced by Bitcoin.
Meanwhile, development activity around quantum resistance has picked up. Owens addressed claims that Bitcoin Core developers are ignoring the issue. Some critics have pointed out that proposals like the BIP 360 soft fork are stalled.
Yet Owens said the pace of related proposals has increased since late 2025. He noted that developer work now spans multiple approaches to the problem. These proposals are not abstract ideas.
Instead, they are being built, reviewed, and debated by experienced contributors within the Bitcoin ecosystem. This growing body of work suggests the issue is receiving serious attention.
Bitcoin Prepares for Quantum Future as Industry Pushes Mitigation Strategies
Other industry participants have also suggested mitigation steps. Bitcoin analyst Willy Woo said in November that holding funds in SegWit wallets over time may reduce risk exposure. Such approaches aim to limit the frequency with which public keys become visible.
Even so, governance remains a major hurdle as Bitcoin operates without a central authority to enforce changes. Any shift toward post-quantum security would require broad agreement across the network. Miners, developers, exchanges, and users would all need to align on proposed updates.
Owens said this structure could complicate implementation. However, he also pointed to shared incentives across the network. An external and technical threat like quantum computing affects all participants. Each group has a direct interest in maintaining Bitcoin’s security over time.
For investors, current risks remain limited but not irrelevant. Quantum threats are recognized, and active work is underway. Progress in both research and development suggests the ecosystem is preparing for future challenges.
