Question for the Bitcoin Pros:
1. Say i send 1000 sats from an KYC Exchange to the first address of my wallet.
2. Then i clear that address. I send 800 sats back to the exchange and pay 200 sats fe...
Your walletโs list of addresses is generated by your xpub (extended public key).
If that xpub (and all of its addresses) have been leaked, then any address you use will be linkable (with some effort) to that initial KYCโd transaction.
I donโt believe you can infer an xpub from a wallet address (although I could definitely be wrong about that, so #asknostr), but your watching wallet software (and I maybe even the node you broadcast transactions to?) can see your xpub/addresses.
So if you use Ledger Live, for example, then Ledger does know all of your addresses. It would take coordination between Ledger and the exchange to dox all of your addresses, but itโs possible in a way that doesnโt exist when you have a separate, KYC-free wallet. (Highly recommend).
The other difficulty (which I think youโre covered in when emptying a wallet) involves change addresses. You can end up accidentally doxxing your stack if you โshareโ a wallet because of how UTXOs are managed.
Itโs 1000% better to have separate wallets, separate stacks, to never need to worry about this.
