Grayscale has downplayed concerns that quantum computing could disrupt Bitcoin or the broader cryptocurrency market in the near term, saying such risks are unlikely to affect prices or valuations in 2026.
In its latest “2026 Digital Asset Outlook” report, the asset manager acknowledged that quantum computing poses a long-term challenge to blockchain cryptography but emphasized that the technology is still far from being powerful enough to threaten Bitcoin’s security in the next few years.
According to Grayscale, a so-called “cryptographically relevant” quantum computer, capable of breaking Bitcoin’s public-key cryptography and forging digital signatures to steal assets, is widely considered unlikely to emerge before 2030 at the earliest.
As a result, the firm believes quantum-related fears should not be a major factor in crypto market pricing over the next year.
Bitcoin relies on elliptic curve cryptography to secure wallets and validate transactions. While quantum computers could theoretically break this encryption, current quantum systems lack the scale, stability, and error correction required to perform such attacks.
Grayscale noted that even under optimistic assumptions, meaningful cryptographic threats remain several years away.
The report added that most public blockchains will eventually need to transition to post-quantum cryptography to remain secure in a future where quantum computing becomes more advanced.
However, these upgrades are expected to occur gradually and well before quantum computers become capable of undermining existing blockchain security.
Grayscale also highlighted that the crypto ecosystem has historically demonstrated an ability to adapt to technological challenges through coordinated software upgrades and protocol changes.
Bitcoin, in particular, has undergone multiple major upgrades over its history without disrupting the network or investor confidence.
While quantum computing remains an important long-term consideration for blockchain developers and researchers, Grayscale concluded that it does not represent a near-term investment risk.
For now, macroeconomic factors, regulatory developments, institutional adoption, and network fundamentals are likely to play a far greater role in shaping Bitcoin’s price performance and overall crypto market valuations in 2026.
