Ethereum co-founder Vitalik Buterin has pushed back against claims that advances in artificial intelligence could cause Bitcoin to lose more than 50% of its value by undermining the network’s security. In remarks reported on September 7, 2026, Buterin said he does not consider the scenario likely and added that approximately 90% of his net worth is effectively positioned against such an outcome.
Buterin also voiced optimism about Bitcoin’s long-term cybersecurity development, arguing that the network can handle cybersecurity threats that do not require social consensus. The comments counter recurring concerns that AI systems could weaken cryptographic algorithms or otherwise compromise Bitcoin’s proof-of-work security. His remarks come amid broader debates about how emerging technologies could impact cryptography and blockchain networks.
Market observers noted that Bitcoin is currently navigating resistance levels around $64,000 to $65,000. Buterin’s comments may reinforce trader confidence in Bitcoin’s stability, though broader cryptocurrency market conditions remain mixed. The discussion highlights ongoing attention to AI, cryptography, and blockchain security as both sectors continue to evolve.
