Vitalik Buterin bets 90 percent of his fortune on conviction that artificial intelligence poses no threat to cryptocurrency security

Ethereum co-founder Vitalik Buterin has directly challenged predictions that artificial intelligence will crater cryptocurrency values, arguing that blockchain networks can withstand AI-driven security threats. His confidence extends to betting roughly 90 percent of his personal net worth on the proposition through his cryptocurrency holdings.

• Buterin rejected Silicon Valley investor Liron Shapiro’s estimate of a 50% probability that Bitcoin falls over 50% within two years due to AI threats.
• Buterin assigned very low probability to scenarios where AI breaks Bitcoin’s hashing functions or proof-of-work system fundamentally.
• Bitcoin swap provider Boltz suspended operations in August after months of automated, AI-assisted attacks overwhelmed its small development team’s ability to patch vulnerabilities.

• 50% Shapiro’s estimated probability of Bitcoin declining more than fifty percent in two years
• 90% Buterin’s cryptocurrency holdings as percentage of his total net worth
• $100M Anthropic’s committed usage credits to Project Glasswing defensive initiative
• 100+ Organizations including Google, Microsoft, OpenAI signing open letter on AI cyberattack risks

The debate over artificial intelligence’s threat to cryptocurrency security has moved from theoretical concern to direct disagreement between two prominent voices in technology. Ethereum co-founder Vitalik Buterin has expressed optimism that AI will not trigger catastrophic losses in Bitcoin’s value, directly contradicting predictions from Silicon Valley investor and AI-risk commentator Liron Shapiro. Shapiro estimated a 50% probability that Bitcoin would fall more than 50% within the next two years, grounding his thesis in concerns that AI could undermine the security guarantees investors believe protect the network.

The disagreement reflects a fundamental uncertainty within both the cryptocurrency and artificial intelligence communities about how rapidly defensive and offensive capabilities will evolve. Proponents of cryptocurrency have long emphasized the security properties of decentralized consensus mechanisms and cryptographic algorithms that underpin blockchain networks. Critics increasingly worry that advances in AI could accelerate the discovery and exploitation of vulnerabilities across the broader cryptocurrency ecosystem, even if Bitcoin’s core protocol remains technically sound.

Buterin’s confidence rests on Blockchain resilience and fixable vulnerabilities

Buterin rejects Shapiro’s bearish case and argues that Bitcoin should weather security failures that do not require social consensus to resolve, such as attacks on clients, mining pools, and supporting infrastructure.

The Ethereum co-founder assigned very low probability to scenarios in which AI produces a fundamental break in Bitcoin’s hashing functions or proof-of-work system. He indicated that he would ordinarily place a monetary wager on such disagreements but noted that his existing cryptocurrency holdings effectively constitute such a bet. Buterin estimated his crypto holdings amount to roughly 90% of his net worth, suggesting his personal financial commitment reflects confidence in major blockchain networks’ ability to resist AI-driven threats.

This distinction between threats to Bitcoin’s core protocol versus threats to supporting infrastructure has become central to debates about cryptocurrency’s AI vulnerability. Bitcoin’s proof-of-work security model depends on cryptographic hash functions like SHA-256, which have resisted attacks despite decades of scrutiny. Even significant advances in quantum computing or artificial intelligence are widely expected to require either fundamental breakthroughs in mathematics or prohibitively expensive computational resources to break these algorithms, though debate continues about the exact timeframes and requirements.

My basic reasons are that I am quite optimistic about cybersecurity in the long term and I see the primary problem as being getting the transition.

Vitalik Buterin, Ethereum co-founder

Buterin expects most AI-driven security failures to remain fixable and believes that defensive capabilities will eventually benefit from the same technological advances that attackers are leveraging. This optimism reflects confidence within parts of the cryptocurrency community that blockchain networks possess inherent resilience through their decentralized nature and transparent consensus mechanisms. The ability to deploy protocol upgrades through decentralized governance, while slow and sometimes contentious, does provide Bitcoin and other major networks with repair mechanisms unavailable to centralized systems.

AI-Assisted attacks already targeting Cryptocurrency infrastructure

Recent incidents demonstrate that the threat Shapiro identified is already materializing, though not through direct attacks on Bitcoin’s core cryptography.

Bitcoin swap provider Boltz suspended operations indefinitely in August after months of automated, AI-assisted probing led to several contained exploits. The attacks accelerated faster than Boltz’s small development team could investigate and patch vulnerabilities. While the company’s non-custodial architecture protected customer funds, Boltz absorbed losses from the exploits and concluded it could no longer operate safely.

The Boltz incident illustrated how AI could pressure the infrastructure surrounding Bitcoin without compromising proof-of-work or breaking the network’s underlying cryptography. Attackers used automation to repeatedly search for weaknesses faster than defenders could respond. The incident raises questions about whether smaller cryptocurrency services and infrastructure providers can maintain adequate security as AI-powered attack tools become more sophisticated and accessible. Boltz’s experience demonstrates that even well-designed systems built by security-conscious developers can struggle against relentless automated probing.

Deddy David, chief executive of blockchain security firm Cyvers, warned that financial exposure from AI-powered cryptocurrency attacks could eventually reach hundreds of millions or billions of dollars, extending across wallets, bridges, exchanges, smart contracts, and the software used to operate blockchain networks. These systems provide attackers with considerably more potential entry points than Bitcoin’s core consensus mechanism itself. The fragmented nature of cryptocurrency infrastructure, with hundreds of separate applications and service providers, creates what security researchers call an asymmetric attack surface where defenders must protect every component while attackers need exploit only one.

Defensive initiatives mobilizing across technology and finance sectors

The technology industry is increasingly mobilizing to ensure that defensive AI develops at least as quickly as offensive capabilities. Anthropic restricted public access to its Claude Mythos model due to its ability to autonomously discover and weaponize software vulnerabilities. The company instead directed those capabilities toward defenders through Project Glasswing, an initiative involving technology companies and financial institutions including Amazon Web Services, Google, Microsoft, and JPMorgan Chase.

Anthropic committed as much as $100 million in usage credits to Project Glasswing, which uses Mythos Preview to identify and repair vulnerabilities in critical systems before malicious attackers can exploit them.

More than 100 organizations, including Google, Microsoft, Anthropic, OpenAI, Capital One, Mastercard, Visa, Adobe, Oracle, and IBM, signed an open letter warning governments and companies that AI-enabled cyberattacks are likely to become substantially more widespread and sophisticated within months. The signatories argued that existing cybersecurity practices will not be sufficient as AI systems become more capable, particularly across historically under-resourced critical infrastructure. Cryptocurrency faces a similar defensive challenge with an additional complication: many crypto systems hold immediately transferable financial assets and operate continuously on publicly visible infrastructure, creating asymmetric risk during the period before defensive tools catch up with offensive capabilities.

The mobilization of defensive resources reflects recognition across multiple industries that AI-powered security threats represent a qualitative shift in how cyberattacks might develop. Unlike previous waves of automated attacks that relied on known exploits, AI systems can discover previously unknown vulnerabilities at speeds that outpace traditional patching cycles. This creates a window of vulnerability that cryptocurrency infrastructure, with its decentralized and heterogeneous nature, may struggle to manage effectively across all participants simultaneously.

Whether Buterin’s optimism about the trajectory of cybersecurity defenses proves justified will likely shape cryptocurrency’s regulatory treatment and institutional adoption in coming years. Regulators watching for signs that AI-powered attacks are causing systemic damage to crypto infrastructure may restrict exposure for regulated entities, potentially triggering the very confidence collapse Shapiro predicts. The resolution of this debate will influence not only cryptocurrency’s future but also broader questions about how financial systems can maintain resilience as AI capabilities accelerate.
