What if Bitcoin’s biggest black swan weren’t a war, regulation, or a financial crisis, but quantum computing?

There’s a scenario that deserves attention: access to old Bitcoin wallets that have been inactive for more than a decade, including some attributed to Satoshi Nakamoto. According to research published by Glassnode in May 2026, around 6.04 million BTC (30.2% of the issued supply) could be potentially exposed to future quantum attacks.

Imagine if one day a single BTC were moved from one of those wallets. The market could panic. And whoever managed to access those funds could take advantage of the situation by opening short positions before a potential crash, profiting on both sides.

The question is: Is Bitcoin prepared to face this scenario? Is there a contingency plan, a migration to quantum-resistant cryptography, or any solution for coins whose owners have lost their keys or are no longer around?

I’m not saying it will happen, but are we building the Bitcoin of the future, or are we relying too much on the future being unable to break it? What would the real plan B be?.
