Simply put
- Grayscale indicated that quantum computing is not expected to influence cryptocurrency prices by 2026, despite ongoing security concerns.
- The firm believes most blockchain technologies will eventually need updates for post-quantum cryptography.
- Grayscale provided estimates suggesting that a quantum system likely won’t be able to crack Bitcoin encryption until at least 2030.
Investment firm Grayscale has published a report arguing that fears surrounding quantum computers potentially compromising Bitcoin’s security are unlikely to affect the cryptocurrency market in 2026. They downplayed the immediate risks associated with this technology.
In their 2026 Digital Asset Outlook, Grayscale referred to quantum computing as a “red herring” for the upcoming year. They noted that while this technology poses long-term challenges for crypto, it isn’t anticipated to have a short-term impact on market prices.
“We believe that research and preparation for post-quantum cryptography will progress, but this issue is not expected to influence valuations next year,” Grayscale analysts commented.
The report concurs with cryptographers who have historically warned that powerful quantum computers could undermine the public-key cryptography securing Bitcoin and other blockchain systems.
Experts have suggested that in such a scenario, it might be possible for an attacker to derive a private key from public information.
“A quantum computer could forge the digital signatures currently used by Bitcoin,” explained Justin Thaler, a research partner at Andreessen Horowitz and an associate professor at Georgetown University. “Therefore, someone with a quantum computer could potentially authorize a transaction that cleans out your Bitcoin account without your approval, which is understandably concerning.”
Grayscale’s report emphasizes that while research into post-quantum cryptography will advance—potentially even quickly—the emergence of a quantum computer capable of decrypting Bitcoin likely won’t occur until at least 2030.
Given this timeline, Grayscale believes the associated risks of quantum computing won’t influence cryptocurrency prices in 2026.
Grayscale has a vested interest in diminishing fears about quantum computing as it broadens its reach in the crypto market to both retail and institutional investors. This includes a new series of exchange-traded products featuring assets like Dogecoin, XRP, and Chainlink.
The perspectives reflected in Grayscale’s report align with those of many blockchain developers concerning timelines discussed in DARPA’s quantum theory. According to their research, quantum computers relevant to cryptography aren’t an immediate threat and will remain several years away.
