If you believe the headlines, quantum computing is a pretty big threat. Maybe not today, but in a decade or three.

I'm aware that we can switch to quantum-resistant cryptography like Lamport one-time signatures, but there is an equally large problem that's gone unaddressed: What do we do about the several million BTC that will remain vulnerable because they are still in ECDSA-secured pubkeys/pubkey hashes? Like the Satoshi coins......do we destroy them?

If not, millions of coins will get stolen and dumped on the markets for years and years. Being a HODLer sounds like a nightmare in that case!
