Secure yourself with 5 steps:

1. Use a modern HD wallet. Any current hardware or standard software wallet generates a fresh address per receive – that alone puts you in the safe column.

2. Never reuse an address you have spent from. Spending reveals the public key forever; anything left behind sits in the exposed pile.

3. If you hold coins on old or reused addresses, move them once to a freshly generated modern address. That single transaction takes them out of the harvest-now-decrypt-later pool.

4. Watch for the upgrade, not the headlines. The milestone that matters is a quantum-resistant address type going live (BIP-360 or a successor) – adopt it when it ships. Chip announcements with bigger qubit counts are not the signal.

5. Do not panic-sell on quantum news. The threat is a solvable, years-away engineering problem the ecosystem is already working on – a reason for hygiene, not for exit.
