Vitalik Buterin: chance of attack on Bitcoin PoW small

Ethereum co-founder Vitalik Buterin has responded to the claim that Bitcoin could lose more than 50% of its value within two years because AI undermines the network’s security. He does not share that concern. Buterin is actually positive about long-term cybersecurity and expects Bitcoin to handle most problems well, provided they do not require broad social consensus.

In short:

• Vitalik Buterin is optimistic about Bitcoin’s long-term cybersecurity.
• He expects network-level attacks to be absorbed by upgrading clients and mining pools.
• He estimates the chance of hashing or proof-of-work actually being cracked as minimal.

Buterin responds to AI security concerns around Bitcoin

The discussion revolves around whether AI poses a real threat to Bitcoin’s cryptographic security. In that debate, Buterin takes an optimistic position. In his view, network-level problems, such as attacks involving clients or mining pools, fall into the category of matters that can be resolved without broader social coordination.

Buterin says he sees the biggest challenge in the transition period towards better security, not in the system itself. He calls the chance that hashing or the proof-of-work mechanism is actually cracked small. Earlier, he already wrote about his expectations regarding efficient cryptography by 2030.

Buterin puts his money where his mouth is

The Ethereum co-founder adds, with a wink, that he does not formally need to make a bet because he already has one running. Roughly 90% of his wealth is in crypto, which he says means he already holds the position that Bitcoin and Ethereum will remain safe.

Bitcoin is currently trading around $79K, down slightly by 0.4% over the past 24 hours. The price is therefore close to a level that analysts consider technically important. Whether Buterin’s remarks will influence market sentiment remains unclear for now.
