Grayscale, one of the world’s largest digital asset managers, has downplayed fears that quantum computers could pose an immediate threat to Bitcoin’s security.
In its latest 2026 Digital Asset Outlook, the company cautioned that quantum computing remains a long-term technology challenge in the crypto sector. Still, the firm stated that the risk is unlikely to impact cryptocurrency markets in the coming year. The report went even further, calling quantum computing a “red herring” for 2026.
Grayscale also highlighted that specific physical factors, regulatory changes, institutional adoption growth, and capital flows will influence crypto markets. Those, the firm said, are the dynamics that will drive market performance in 2026 — not unfounded fears about technology that lies ahead in the future.
Grayscale downplays quantum risk in the short term
Grayscale maintains that even a quantum computer capable of breaking Bitcoin’s cryptography will not be built for at least another 10 years, until 2030 at the earliest. Analysts, meanwhile, said that research into post-quantum cryptography will continue — and probably accelerate in pace — but that this should not have an immediate impact on the price of cryptocurrency.
Positioning quantum computing as a future challenge, rather than an immediate threat, is part of Grayscale’s plan to reassure investors of its commitment to sustaining the market’s momentum in the digital asset sector.
Grayscale stated in its report that research and preparedness for post-quantum cryptography will continue, but it is unlikely to impact market valuations over the next 12 months. The firm emphasized that quantum computing remains a long-term concern rather than a near-term driver for crypto markets.
Grayscale’s position is particularly interesting as it becomes increasingly active in both retail and institutional spaces. The firm has introduced a variety of exchange-traded products tied to cryptocurrencies, including Dogecoin, XRP, and Chainlink, over the past year, which has enabled it to strengthen its coverage within the digital asset space.
Cryptographers have long warned that, in theory, a quantum computer could break the security of public-key cryptography, which underpins Bitcoin and all other forms of blockchain technology. This would, in turn, enable attackers to calculate private keys from public information and forge digital signatures.
Justin Thaler, a research fellow at Andreessen Horowitz and an associate professor at Georgetown University, warned that a powerful quantum computer could compromise Bitcoin’s security. He said such a machine could forge the digital signatures Bitcoin uses today, potentially allowing someone to authorize transactions without the owner’s consent and effectively steal funds.
However, many experts emphasize that this is decades away. Researchers have noted that cryptographically significant quantum computers are not yet in sight, and migration paths can be taken to upgrade Bitcoin’s cryptography before it becomes seriously threatened.
Markets and custodians brace for Quantum risks
The outlook from Grayscale is reassuring to investors, suggesting that the situation on Wall Street will return to normal. The firm makes this clear, reassuring those in the crypto markets that quantum computing is a concern for years to come, not now.
This is important because Grayscale’s reports and products set the tone for both large institutional participants and retail traders.
In the meantime, experts recommend that major custodians and exchanges remain vigilant. Institutions that hold a large amount of Bitcoin may face higher operational risk if quantum cryptography is a concern.
