This is enough reason for people who care about privacy to avoid using wallets without coin control features. Imagine having your 10BTC Non-KYC coins wrecked by 0.000001 KYC coins in a dusting attack with no coin control to freeze the dust coins.
Many still don't understand how Dangerous dusting attack could be.
I think this shouldn’t even be about coin control alone, people should also prioritize the use of different addresses for a different transaction. Aside the usual dust attacks that one isn’t aware off. For someone having 10 bitcoin or even 1 bitcoin giving out same address to actually receive more bitcoin will only expose one privacy. For me to avoid all this tainted transactions been infected. It is advisable to mostly use different address for new transactions most especially coins from total strangers.
Using a total different address wouldn’t expose the holdings of the address. Most at times if a tainted UTXO is sent to an address it is not always this tainted UXTO that’s flagged but the entire address and coins coming from the address whether a tainted UTXO or not the address is flagged, but with a different address you can avoid mixing the coins better when on different addresses
