Imagine that you have a more secure network than the bitcoin network. Yes, it is e.cash - XEC - bitcoinABC. It provides a PoW hash system with avalanche pre-consensus. It confirms transactions with staked XECs in nodes. It is not just PoS - it is PoW+PoS= built together. A separate security confirmation. And I want to say - that with a wallet like electrumABC wallet - with cashfusion (internal common currency system) and one-time addresses + avalanche pre-cons. confirmation. IT IS the world's first quantum-proof wallet (even without a quantum-proof code).
1. if you use cashfusion (the same is true for BCH wallets) - then the quantum computer will not specifically find your address anymore, where your values ββare. (In case of a KYC-AML leak, your addresses will not be public)
2 if you use one-time addresses (by default) - the public key of your addresses will not be leaked.
3. if you use the tor option - which the wallet proxy offers - then neither the quantum government nor quantum crooks can find your ISP and IP addresses. No connection.
4. as always - your seed phrases must be in a safe place - must not be leaked.
