Would moving Bitcoin from Taproot to SegWit make it permanently quantum-safe?

No. It can change at-rest key exposure characteristics, but regular spending and future attacks still require an eventual protocol-level migration.

The answer

No. It can change at-rest key exposure characteristics, but regular spending and future attacks still require an eventual protocol-level migration.

What to do next

Do not move coins solely on an unverified quantum scare; assess fees, key exposure and wallet compatibility.
