Vitalik Buterin says crypto exchanges are preparing for “bunker mode” as October hacks hit $6.48 billion

Ethereum co-founder Vitalik Buterin says market participants are increasingly treating the next two years as a survival exercise, not a growth contest. For crypto exchanges and other high-risk payment operators, that usually means tightening infrastructure, reducing attack surface, and assuming the obvious target is now the wallet, the UI, or the centralized layer sitting in the middle.

1. Buterin said more people in the crypto market now understand that their main responsibility over the next two years is “not to win, but to survive.” In his words, this means entering “bunker mode,” and he expects Binance and other large market participants to do the same.
2. He also pointed to a shift in the type of attacks hitting the industry. According to Buterin, attacks on smart contracts have decreased, while recent major incidents have mainly affected user interfaces and centralized infrastructure components. His takeaway was straightforward: the underlying base of projects is more protected than before, so attention should move to the weakest links in the ecosystem.
3. For DeFi, Buterin argued that security needs to come first. He said users care more about avoiding total loss of funds than about chasing a small yield difference. The areas he sees as most promising are “high-performance DeFi” and privacy technologies.
4. He also said artificial intelligence is accelerating Ethereum development, claiming that tasks that would have taken about 20 years five years ago can now be done much faster. On quantum resistance, Buterin said code for quantum-resistant wallets has already been developed and formally verified. His basic recommendation for storing funds: use multisig (multi-signature) setups.
5. The timing matters. In October, the crypto industry suffered 56 major hacker attacks with total losses of a record $6.48 billion, according to PeckShield. That was up 745% from September’s $766.49 million, and about 97% of October losses came from the hack of Binance, the world’s largest crypto exchange.

For PSPs, acquirers, and banks touching crypto flows, the practical reading is not subtle: large platforms are talking openly about defense, not expansion, and the main failure points are moving away from the smart contract layer toward infrastructure and access points that sit closer to users and operations.
