Back rejects freezing or protocol changes, arguing the threat will trigger a market event rather than a developer decision, and that immutability and personal wallet security should prevail.

The security debate intensifies amid Google's quantum breakthrough, heightening expectations about Q-Day when quantum computers could break Bitcoin keys.

Woo warns that those 4 million BTC could be flooded back into circulation if quantum computers break private keys, exerting price pressure.

Adam Back and Willy Woo debate how to address the risk posed by inactive funds as Q-Day approaches.

Current quantum capabilities are still far from breaking Bitcoin keys, but concern about Q-Day and its potential impact on prices and security is rising.

Back emphasizes personal responsibility for wallet security, warning that users who lose keys will be rugged by the market anyway, with developers not preemptively intervening.

As the quantum threat grows more real, the market will recognize the primacy of immutability and personal responsibility, rather than a rug-pull-style intervention by developers.

Attention centers on roughly 4 million inactive Bitcoins in older addresses that could be vulnerable once quantum access becomes possible.

The discussion centers on Bitcoin’s broader security, decentralization, and whether protocol changes should address post-quantum risks or rely on market dynamics, framing the debate around user responsibility for wallet security rather than node or protocol interventions.

Back argues that those who fail to secure their wallets are already exposed, and any centralized rescue or freezing of funds would be a rug pull that undermines decentralization.

Willy Woo advocates freezing the affected coins to prevent movement and to upgrade wallets to quantum-resistant standards, noting it would alter monetary policy and property rights but protect holders.

Woo outlines two options: freeze vulnerable coins by changing monetary policy or leave them as is and risk a price collapse if hackers access them; he favors freezing as a form of upgrading wallets to quantum resistance.
