Vitalik Buterin

What did Vitalik say about Ethereum recently?

In the first week of October 2026, Vitalik warned that artificial intelligence could one day crack some of the math that keeps crypto wallets safe. He said people don't need to panic right now, but the threat is real enough to start preparing. He also shared that about 90% of his own net worth is still in cryptocurrency, calling that an implicit bet that digital security will hold up over time.

What does he actually mean?

He's saying Ethereum's long-term safety depends on upgrading its locks before smarter AI learns to pick them. He's not running for the exits himself, but he's openly naming the danger.

Why does this matter for regular people?

If you hold ETH, the person who helped create it is flagging a specific technical risk while still keeping his own money in it. That mix of caution and commitment tells you where his head is: watchful, not alarmed.
