Cardano's Hoskinson says Bitcoin's quantum fix is a hard fork that can't save Satoshi's coins

[David74]

Charles Hoskinson argues that Bitcoin's proposed quantum defence would effectively need a hard fork and still would not protect very old coins. The interesting part is not just the technical claim, but the governance problem it points to. If quantum risk becomes urgent, Bitcoin may have to choose between purity, security and ownership rights.

Freezing old coins would be a huge line to cross.

Bitcoin governance was always going to struggle with a problem this big.

Hoskinson may be right on the hard fork point, even if people dislike the messenger.

Quantum risk still feels distant, but migration planning cannot wait forever.
