Bitcoin developers are researching address types that use quantum-resistant signatures. Once those are created, you should be able to simply move your coins to such an address to mitigate the quantum computer threat in the future.
If Bitcoin developer finally come up the solutions to this problem, then most of the wallet we using will be uninstalled, and more new wallets will be created as well?
I'm just thinking this maybe these quantum resistance addresses will be supplied to every wallets out there?
How would it done?
I do think they would just get updated with the ability for such addresses and to manually move your BTC there.
