Artificial intelligence is creating new opportunities across the technology sector, but its rapid development is also raising questions about the future security of cryptocurrencies. Experts are now debating whether increasingly capable AI systems could discover mathematical techniques that weaken the cryptographic mechanisms protecting Bitcoin and other digital assets.
According to a report published by BanksNews.am on October 9, 2026, analysts associated with blockchain analytics firm Glassnode estimate that more than 21% of Bitcoin may face potential vulnerability related to developments in AI-assisted cryptanalysis.
The discussion has attracted different reactions from prominent figures in the crypto industry. While some experts believe the possibility deserves serious preparation, others argue that there is currently no convincing evidence that AI has broken the cryptographic foundations protecting Bitcoin wallets.
Why Is AI Raising Concerns About Bitcoin Security?
Bitcoin relies on cryptographic techniques to protect wallets and authorize transactions. These mechanisms help ensure that only someone possessing the appropriate private key can authorize the transfer of funds.
One of the central concerns involves elliptic-curve cryptography, which underpins widely used digital signature systems. These systems are designed so that deriving a private key from its corresponding public key is computationally impractical with currently known methods.
However, advances in artificial intelligence could potentially accelerate mathematical research and help identify new approaches to difficult computational problems.
Ethereum researcher Justin Drake has warned that AI-assisted mathematical discoveries could challenge assumptions underlying existing cryptographic systems sooner than some experts expect. In a worst-case scenario, he suggested that a breakthrough could occur within months rather than years.
This is a warning about a possible future development, not confirmation that Bitcoin's cryptography has already been compromised.
Why Could More Than 20% of Bitcoin Be at Risk?
The concern highlighted in the report relates to Bitcoin holdings whose public keys have already been exposed on the blockchain.
Public keys are part of the cryptographic system that allows networks to verify transactions. Their visibility is not, by itself, a security failure. The security model depends on the computational difficulty of deriving the corresponding private key.
If a practical method were discovered to overcome that difficulty, coins associated with exposed public keys could face increased risks.
The Glassnode-related estimate cited by BanksNews.am places the potentially affected share above 21% of Bitcoin. This figure should not be interpreted as meaning that those coins have been stolen or that an AI system can currently access them.
Instead, it reflects concerns about how a hypothetical cryptographic breakthrough could affect certain Bitcoin holdings.
The actual level of risk would depend on the nature of any breakthrough, the cryptographic systems involved, and the ability of Bitcoin developers and users to respond.
Experts Disagree About the Severity of the Threat
The discussion has revealed different perspectives within the cryptocurrency industry.
Justin Drake Calls for Preparation
Justin Drake has encouraged the blockchain industry to begin preparing for a scenario in which existing cryptographic protections could become vulnerable.
His recommendation includes planning for a controlled migration of funds to new addresses whose public keys have not previously been exposed on the blockchain.
The broader argument is that preparing security upgrades in advance could give cryptocurrency networks more time to respond if a serious vulnerability were discovered.
Coinbase's Yehuda Lindell Questions the Warning
Yehuda Lindell, a cryptography expert associated with Coinbase, has challenged the warning, arguing that there is no clear evidence that the long-standing mathematical assumptions behind elliptic-curve cryptography have been broken.
His position highlights an important distinction: advances in AI and mathematics do not automatically translate into a practical method for recovering cryptocurrency private keys.
Haseeb Qureshi Supports a Cautious Approach
Haseeb Qureshi of the investment firm Dragonfly has expressed support for taking the possibility seriously.
From this perspective, preparing for a potential weakness can be reasonable even before a practical attack has been demonstrated, particularly when the consequences could affect substantial amounts of digital assets.
The disagreement illustrates the challenge facing the industry: how to prepare for emerging technological risks without creating unnecessary panic.
Does This Mean Bitcoin Is No Longer Safe?
No confirmed AI breakthrough has demonstrated that Bitcoin's underlying cryptographic protections can currently be defeated in the manner described by these warnings.
It is important to distinguish between a theoretical risk, a possible future development, and an existing, exploitable vulnerability.
Bitcoin's security depends on cryptographic algorithms, software implementations, private-key management, and the ability of its development community to respond to new threats.
Even if AI-assisted mathematical research advances rapidly, a practical attack against widely used cryptographic systems would require more than general improvements in AI capabilities.
At the same time, the discussion reinforces the importance of ongoing security research and long-term planning across the cryptocurrency ecosystem.
Users should avoid making rushed transfers based solely on alarming headlines. Moving assets incorrectly can create its own risks, including sending funds to the wrong address or losing access to a wallet.
How Can Cryptocurrency Holders Protect Their Assets?
Although the specific AI-related threat remains uncertain, users can take practical steps to strengthen their general cryptocurrency security.
Use Secure Wallets
Choose reputable wallets and keep their software updated. Understand how your wallet manages private keys and recovery phrases.
Protect Your Recovery Phrase
Never share your seed phrase or private keys with anyone. Store recovery information securely and be cautious of websites, messages, or applications requesting access to your wallet.
Verify Every Transaction
Before sending cryptocurrency, check the recipient's address, the asset, and the blockchain network. Cryptocurrency transfers are generally irreversible.
Follow Reliable Security Updates
Monitor announcements from established blockchain projects, wallet developers, and recognized security researchers. If a genuine vulnerability is confirmed, follow verified guidance rather than relying on unverified social media claims.
Avoid Panic-Driven Decisions
The possibility of a future vulnerability does not automatically mean immediate action is necessary. Before moving funds or changing wallet arrangements, understand the technical risks and verify any recommended procedure.
What Could This Mean for the Future of Cryptocurrency?
The debate around AI and Bitcoin highlights a broader challenge for the digital asset industry: cryptographic systems must remain resilient as computing technologies evolve.
Developers may need to investigate new security approaches, evaluate migration strategies, and prepare contingency plans for potential cryptographic weaknesses.
These discussions are not limited to Bitcoin. Other blockchain networks also rely on cryptographic methods to protect wallets, validate transactions, and maintain network security.
The pace of AI development makes continued research important, but the outcome remains uncertain. The industry's response will depend on evidence, technical testing, and the ability to implement secure changes without exposing users to additional risks.
Conclusion
Artificial intelligence has intensified discussions about the long-term security of Bitcoin and other cryptocurrencies. A report cited by BanksNews.am highlights an estimate that more than 21% of Bitcoin could face potential vulnerability if future advances undermine the cryptographic assumptions protecting certain holdings.
However, experts disagree about the likelihood and timing of such a development. Some recommend preparing for potential risks, while others emphasize that there is currently no clear evidence that Bitcoin's underlying cryptography has been broken by AI.
For cryptocurrency holders, the most practical approach is to maintain strong wallet security, follow verified technical updates, and avoid making rushed decisions based on speculation.
