Vitalik Buterin Backs Bitcoin
Vitalik Buterin rejects investor forecast that artificial intelligence could undermine Bitcoin security.

Key Points
1
Liron Shapira assigned a 50% probability to his forecast, arguing that Bitcoin could lose more than half its value through a loss of user confidence even before any cryptographic flaw was actually exploited.
2
Buterin framed the main near-term challenge as managing the transition to increasingly capable AI attackers and defenders, rather than a permanent failure of Bitcoin’s cryptography.
3
Buterin separately pointed to rapid advances in succinct proofs, or SNARKs, and fully homomorphic encryption, saying that the availability of many hard problems gives cryptography new ways to recover as older assumptions weaken.
4
The articles note that a practical break of SHA-256 would have implications far beyond Bitcoin, potentially threatening widely used security systems in banking, military communications and the broader internet.
5
AI was described as a potential defensive tool as well as an attack tool: defenders could use it to review code, test patches and detect suspicious activity affecting nodes, wallets, mining pools and communications infrastructure.
Ethereum co-founder Vitalik Buterin has rejected investor Liron Shapira's prediction that artificial intelligence could crash Bitcoin's price by more than 50% within two years. Coin Codex reported that Buterin dismissed concerns about AI undermining Bitcoin's security, instead arguing that most attacks would target peripheral systems like mining pools and node software—issues that software updates could fix without changing Bitcoin's core rules.
Buterin doubled down on his confidence by revealing that roughly 90% of his net worth is positioned against such a collapse, mostly through Ethereum holdings. CoinGabbar noted that Buterin assessed the risk of AI breaking Bitcoin's cryptographic hash function as extremely low, while acknowledging that the transition to more capable AI attackers and defenders presents real challenges ahead.
Shapira's 50% Probability Bet on Bitcoin Failure
Liron Shapira, a commentator on the Doom Debates podcast, assigned a 50% probability to his forecast that Bitcoin could lose more than half its value within two years. The News Crypto reported that Shapira argued a price collapse could happen even before any actual cryptographic flaw was discovered—simply through loss of user confidence as AI capabilities advanced.
Why Bitcoin's Core Security Likely Survives AI Threats
Buterin framed the real challenge differently. Kucoin explained that he identified peripheral infrastructure—not Bitcoin's core cryptography—as the main vulnerability to AI attacks. Software patches could address compromised node software, mining pools, and network systems without needing to change Bitcoin's fundamental rules or proof-of-work mechanism.
Buterin also highlighted rapid advances in mathematical tools like succinct proofs (SNARKs) and fully homomorphic encryption. Crypto News reported that he argued the availability of many hard problems means cryptography has new ways to recover if older security assumptions weaken over time.
AI as Both Weapon and Defender Against Attacks
The debate highlighted that artificial intelligence could work both ways in Bitcoin's security ecosystem. The News Crypto noted that defenders could use AI to review code, test security patches, and detect suspicious activity targeting nodes, wallets, and mining pools. This dual-use nature means improved AI could strengthen Bitcoin's defenses just as much as it might threaten them.
The Broader Stakes Beyond Bitcoin
A practical break of SHA-256 (Bitcoin's hash function) would have massive implications far beyond cryptocurrency. Ethereum Founder noted that such a breakthrough would threaten security systems used across banking, military communications, and the broader internet. This context suggests that Bitcoin's cryptography is part of global infrastructure millions of people depend on daily.
