The quantum threat to crypto isn't coming "someday" — security researchers just warned that AI is actively compressing that timeline, and most of the market is still pricing it at zero.
Here's what matters: it's not just that quantum computers will eventually crack current cryptographic standards. It's that AI-assisted quantum research is making the breakeven window shorter than anyone modeled three years ago.
Some chains are already building ahead of this.
$ADA has made post-quantum cryptography a governance priority.
$ETH researchers are publishing on quantum-safe signature schemes.
$BTC faces the hardest path — protocol-level upgrades require broad consensus on a chain that resists change by design.
Most cycles, security infrastructure gets priced in after an incident, not before. That's the window.
This isn't a prediction that quantum breaks crypto next year. It's a reminder that value accrues to chains that solve problems before they become crises.
While everyone is watching the 74K recovery and the May 29 expiry, the researchers are watching something else entirely. The chains building post-quantum defenses now will look very different in hindsight.
