Isn’t bitcoin already quantum-proof, though?
Some people say it is, but sometimes you reveal your public key and then you are breakable if there is a computer which is strong enough. There’s a tiny time window where I will send my public key along with the transaction I want to inject into the system, 10-20 minutes or so, and if it stays here too long maybe a quantum computer can crack them before they are on the chain.

the idea is never use same wallet more than once. and use newer wallets P2SH ie. address starting with 3 i.e. multisig and you will be safe
