Well, see, that's the great thing. If you post an address for Monero, it doesn't matter because of the functionality Monero has to hide the sender, the receiver, and the amount received or sent.

You can't see amounts and addresses on-chain

Monero stealth addresses make it so every Monero user is equally likely to have been the receiver

It also uses pedersen commitments so its amount privacy is quantum computer proof

Addresses are also quantum computer proof *if* an adversary doesn't have access to the original address - meaning if you privately DM shortwave your Monero address on something like SimpleX (which uses quantum-resistant encryption), mail them it, or show them your address in person, that is also safe from an extreme scenario like quantum computers.

That's why it's so great. Don't take my word for it though. I encourage you to fact check me on all this.
