Bitcoin's biggest vulnerability isn't quantum computing.
It's governance.
Bitcoin's greatest feature, its resistance to change is slowly become its biggest flaw.
To protect against quantum threats, Bitcoin would need a protocol level fork. Likely changing signature schemes entirely.
But Bitcoin doesn't do forks easily. The community fought for years over block size. Imagine the war over quantum resistance.
By the time the threat is "imminent enough" for consensus, it might already be too late. The Lindy effect works until it doesn't.
Meanwhile, Ethereum? Solana? Privacy coins? New chains?
They ship upgrades. They iterate. They've already made quantum resistance part of the roadmap discussion not as an emergency, but as infrastructure.
Bitcoin's immutability is its core selling point as a store of value.
But a store of value that can't adapt to an existential cryptographic threat... isn't one.
If quantum becomes a credible near term risk, capital doesn't wait for Bitcoin governance to figure itself out. It flows to whichever chain solved the problem yesterday.
The most adaptable store of value wins.
